INTRODUCTION
The HD2103.1 and HD2103.2 are portable instruments with a large LCD display. They are designed for use in the fields of air conditioning, heating, ventilation and environmental comfort. They use hot-wire or vane probes to measure air speed, flow rate, and temperature inside pipelines and vents. Temperature only is measured by immersion, penetration or air contact probes. The temperature sensor used can be chosen from the Pt100, Pt1000 or Ni1000. The probes are fitted with the SICRAM module, with the factory calibration settings already being memorized inside.
The HD2103.2 instrument is a data logger. It memorizes up to 38,000 samples which can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The memorization interval, printing, and baud rate can be configured using the menu. The HD2103.1 and HD2103.2 models are fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer. The Max, Min and Avg function calculate the maximum, minimum or average values. Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off that can also be disabled. The instruments have IP66 protection degree.
This manual describes the HD2103.1 and HD2103.2 models: if not otherwise specified, the description is intended to be applicable to both models.

KEYBOARD AND MENU DESCRIPTION
Foreword The instrument keyboard is composed of single-function keys, like the MENU key, and doublefunction keys such as the ON-OFF/Auto-OFF key. In the double-keys, the function in the upper part is the “main function”, while the one in the bottom part is the “secondary function”. When the instrument is in standard measurement mode, the main function is active. In the menu or in conjunction with the FUNC key, the secondary function is enabled. The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the wrong key is pressed. Each key specific function is described in detail below.

ON-OFF/Auto-OFF key
The instrument is turned on and off using the ON/OFF key. The turning on enables all display segments for a few seconds, starts an auto-test including the detection of the probe connected to the input, and sets the instrument ready for normal measurement.

mm kµ

mcimn 23s

MIN

During turning on, should no probes be connected, the message “NOPRBE SER_NUM” is displayed in the line of symbols for a few seconds, and in the main line a series of dashes appears while the ERR message replaces the temperature. When the probe is inserted into a functioning instrument, the “NEW_PROB_DET” (New probe detected) message appears: as the probe’s data are captured upon turning the instrument on, it is necessary to turn the instrument off and on again. Replace the probes when the instrument is off.

Automatic turning off

The instrument has an AutoPowerOff function that automatically turns the instrument off after about 8 minutes if no key is pressed during the intervening time. The AutoPowerOff function can be disabled by holding the HOLD key pressed down when turning the instrument on: the battery symbol will blink to remind the user that the instrument can only be turned off by pressing the <ON/OFF> key.

V2.4

The automatic turning off function is disabled when external power is used. On the other hand, it cannot be disabled when the batteries are discharged.

FUNC/ENTER key
During normal measurement this enables the display and logging of the maximum (MAX), minimum (MIN) and average (AVG) value of the measurements captured by the probe connected to the instrument, updating them with the acquisition of new samples. The acquisition frequency is once a second. The calculation is performed on the variable appearing on the display upon pressure of the FUNC key: by changing the variable or unit of measurement, the Max, Min and Avg values are cleared. The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even after exiting the calculation function. To reset the previous values and restart with a new measurement session, press FUNC until the message “FUNC CLR” appears, then use the arrows to select YES and confirm using ENTER.
In the menu, the ENTER key confirms the current parameter and then goes to the next one. Pressed together with the UNIT/DuctCalc key, enables the flow rate calculation (please see the UNIT key description).
Attention: the data captured using the Record function cannot be transferred to the PC.

HOLD/ key
It increases the current parameter when used in the menu; when used in measurement mode, it freezes the measurement in progress, and upon application of pressure on the key, the message HOLD appears in the upper side of the display. To return to the current measurement, press the key again. Upon turning on the instrument, the AutoPowerOff function can be disabled by holding the HOLD key down (please see the ON-OFF key description). During calculation of the flow rate (Duct Calc), pressing this key adds a new sample.

UNIT/DuctCalc key

In measurement mode, it allows selection of the unit of measurement of the main input quantity (shown in the central line of the display). By repeatedly pressing the function key, the different units of measurement are shown in sequence:

· wind speed: m/s – km/h – ft/min – mph (miles/hour) – knots

· calculated flow rate: l/s (litres/s) – m3/s – m3/min – m3/h – ft3/s – ft3/min

· the apparent temperature WCT (wind chill equivalent temperature)

The WCT parameter represents the apparent temperature in presence of cold wind and is determined up to an actual temperature of 10°C. Above this limit the display shows an error (ERR).

This setting changes the information displayed and the immediate print of data (SERIAL key). The data recorded using the LOG function (HD2103.2) and those sent to the printer or PC through the serial port using the SERIAL function (HD2103.1 and HD2103.2), keep the chosen unit of measurement and display it.

Spatial averaging calculation

Simultaneously pressing the FUNC and UNIT keys starts the spatial averaging calculation, using the unit of measurement selected with the UNIT key. It is possible to calculate the spatial averaging, of the wind speed or flow rate i.e. across a section of a duct. Please see the paragraph dedicated to wind speed measurement on page 14.

°C/°F – ESC key
Changes the unit of measurement for the temperature between Centigrade or Fahrenheit. When used in the menu, it clears or cancels the active function. It allows exiting the spatial averaging calculation (Duct Calc).

REL/ key
In measurement mode, it displays the difference between the current value and that measured on pressing the key for both measurements – main and secondary. The REL message appears on the display; press the key again to return to the current measurement. When used in the menu, it decreases the current variable value.

MENU Key

The first menu item is accessed by initially pressing on the MENU key; press ENTER to go to the following items. To modify the item displayed, use the arrow keys ( and ). The current value is confirmed by pressing the ENTER key and the display moves on to the next parameter, the setting is cancelled by pressing the ESC key. To exit the menu, press the MENU key at any time.
The menu items are listed in this order:

Probe type: the message “>>>_PRBE_TYPE” is scrolled in the comment line. The main line in the center of the display shows the type of probe connected to the instrument. The following probes can be connected to the input: · hot- wire probes complete with SICRAM module · vane probes complete with SICRAM module

· temperature probes Pt100 complete with SICRAM module · direct 4-wire Pt100 probes complete with TP47 module · 2-wire Pt1000 probes complete with TP47 module · 2-wire Ni1000 probes complete with TP47 module
Upon turning on the instrument automatically detects the probes fitted with SICRAM module: the Probe Type menu item is configured by the instrument and cannot be modified by the user.
Upon turning on, the direct 4-wire Pt100, the Pt1000 and Ni1000 temperature probes display the message “NO_PRBE_SER_NUM”. In this case the probe type must be entered manually. Select Probe type using the MENU key and then select the type of probe used with the arrow keys; confirm using ENTER.
2) SECT m2 – SECT inch2: this parameter defines a duct’s section area for flow rate calculation. It is expressed in m2 or inch2. To change the unit of measurement, press UNIT. Use the arrows and confirm with ENTER. Please see the paragraph dedicated to wind speed measurement on page 14.
3) AVG TIME SECS: time interval according to which the moving average is calculated, in seconds, during measurement of the flow. The value ranges from 1 (no average) to 99 seconds. Please see the paragraph dedicated to wind speed measurement on page 14.
4) Management of memorized data (only HD2103.2): the message “>>>_LOG_DUMP_or_ERAS” (Transfer data or erase) is scrolled in the comment line. The center figure reports the number of free memory pages (FREE). All memory data are permanently erased by pressing SERIAL/EraseLOG. By pressing LOG/DumpLOG, the data transfer of the logged data on the serial port is started: the “BAUD-RATE” must have previously been set to the maximum value (please see the menu items described below and the paragraph “STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER” on page 34).
5) Sleep_Mode_LOG (Automatic turning off during recording) (only HD2103.2): this function controls the instrument’s automatic turning off during logging, occurring between the capture of a sample and the next one. When the interval is lower than 60 seconds, the instrument will always remain on. With intervals greater than or equal to 60 seconds, it is possible to turn off the instrument between loggings: it will turn on at the moment of sampling and will turn off immediately afterwards, thus increasing the battery life. Using the arrows select YES and confirm using ENTER in order to enable the automatic turning off, select NO and confirm to disable it and keep the instrument on continuously. Note: even if Sleep_Mode_LOG=YES is selected, the instrument does not turn off for less than one minute intervals.
6) Print and log interval: sets the interval in seconds between two loggings or data transfers to the serial port. The interval can be set at 0, 1s, 5s, 10s, 15s, 30s, 60s (1min), 120s (2min), 300s (5min), 600s (10min), 900s (15min), 1200s (20min), 1800s (30min) and 3600s (1hour). If the value 0 is set, SERIAL works on command: the sending of data to the serial port is performed each time the key is pressed. Recording (LOG) is performed with one second intervals even if the interval is set to 0. With an interval from 1 to 3600s, continuous data transfer is started when the SERIAL key is pressed. To end the recording (LOG) and continuous data transfer operations (SERIAL with an interval greater than 0), press the same key again.

Use the arrows to set the current minute plus one, and as soon as that minute is reached press UNIT: this synchronizes the time to the second. Press ENTER to go onto the next item.
BAUD_RATE: indicates the frequency used for the serial communication with the PC. Values from 1200 to 38400 baud. Use the arrows to modify this parameter and confirm using ENTER. The communication between instrument and PC (or serial port printer) only works if the instrument and PC baud rates are the same. If the USB connection is used this parameter value is automatically set (please see the details on page 34).

LOG/DumpLOG key – only HD2103.2
In measurement mode, this function starts and stops the logging of a data block to be saved in the instrument’s internal memory. The data logging frequency is set in the “Print and log interval” menu parameter. The data logged between a start and subsequent stop represent a block. When the logging function is on, the LOG indication is on the display, the battery symbol blinks and a beep is issued each time a logging occurs; when using an external power supply the battery symbol does not appear. To end the logging, press LOG.
The HD2103.2 can turn off during logging between one capture and the next: the function is controlled by the Sleep_Mode_LOG parameter. When the logging interval is less than one minute, the logging instrument remains on; with an interval of at least one minute, it turns off between one capture and the next if the parameter Sleep_Mode_LOG=YES.

Dump LOG – only HD2103.2

Press the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on the LOG key: the transfer of the data contained in the instrument internal memory via the serial port is started. Please see the paragraph dedicated to data transfer on page 34.

V2.4

THE PROBES
The instrument works with hot-wire, vane and temperature probes fitted with the SICRAM module. It works also with temperature probes with 4-wire Pt100, 2-wire Pt1000 or Ni1000 sensors.
Some probes are fitted with SICRAM module that acts as an interface between the sensor on the probe and the instrument. There is a microprocessor circuit with a permanent memory inside the module that enables the data logger to recognize the type of probe connected and to read its calibration information.
The temperature probes without SICRAM module are not automatically detected by the instrument and must be set up in the Probe type menu item (please see the description of the menu on page 10).
The probe is detected during turn on, and this cannot be performed when the instrument is already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it off and on.

WIND SPEED MEASUREMENT
The AP471 and AP472 series probes measure the incident wind speed and flow rate; some also measure air temperature. The hot-wire measurement principle is used for the AP471 series and the vane principle for the AP472 series. On request, the probes of the AP471 and AP472 series can be fitted with a telescopic rod that eases measurements in areas difficult to reach (for example vents). The typical applications are wind speed and flow rate checks in air conditioning, heating and cooling systems, or environmental comfort determination, etc. Hot-wire probes are usually employed for precise measurements with low-medium wind speeds (up to 10 m/s), the vane probes with speeds from 5 to 50m/s. In addition, the measured fluid temperature must be considered: the probes measure air flows at 80°C maximum temperature.
The measurements provided by the instrument using the probes are: wind speed, flow rate, and air temperature.
Connecting the probe and turning the instrument on, it is possible to choose the unit of measurement for the value displayed in the main line by using the UNIT key. The following units are available:
· for wind speed: m/s – km/h – ft/min – mph (miles/hour) – knots; · for air temperature: °C and °F; · for flow rate: l/s (litres/s) – m3/s – m3/min – m3/h – ft3/s – ft3/min.
Also the WCT apparent temperature in the presence of air flows is calculated.

Flow rate measurement
The flow rate measurement requires knowledge of the duct or vent area orthogonal to the flow: the menu items indicated by “SECT m2” and “SECT INC2” define the section area m2 or inch2. To set the area value, select the “SECT m2” menu item, and using the arrows, set the desired value. Confirm the selection by pressing the ENTER key.

HD2103

– 14 –

V2.4

To set the measurement in inch2, select the “SECT m2” menu item, and using the UNIT key, change the unit of measurement from m2 to inch2. Proceed to enter the data using the arrows: confirm with ENTER.
The area comprised must be between 0.0001m2 (1cm2) and 1.9999m2.
After input of the duct’s section area, select the unit of measurement for the flow rate by using the UNIT key: l/s – m3/s – m3/min – m3/h – ft3/s – ft3/min. The display shows the calculated flow rate on the section set with the parameters “SECT m2” and “SECT INC2″.
To obtain the correct flow rate measurement, the fact that the air speed is not constant on the section but varies from point to point needs to be considered, therefore an average speed over the entire section is required. Furthermore, the speed varies through time at the same point. This is particularly true when the surface considered is wide or when turbulence is generated, near a grid or diffuser. The anemometers provide some solutions in order to obtain correct measurements even in presence of these disturbance phenomena.

Spatial averaging (Duct Calc function) It is always best to perform the measurements at different points and consider the average value as the valid data. Using the Duct Calc function (sub-function of the UNIT key), the HD2103.1 and HD2103.2 anemometers can capture more than one measurement and supply the maximum, average, and minimum value. In particular, the average value (AVG) is the most important as it supplies the average speed, and therefore the calculated flow rate along the entire section and not on a single measurement point.
Procedure: Using the UNIT key, select the speed or flow rate unit of measurement for which you wish to obtain the average, maximum, and minimum. Enable the calculation function by pressing simultaneously the DUCT CALC and FUNC keys: the central line of the display shows the instantaneous value of the selected variable (speed or calculated flow rate) while the lower line figure indicates the number of times the measurement has been logged. The measurement can be interrupted and there are no time limits to abide by between two subsequent measurements. The captured values are not erased, so it is possible to get some samples, turn the instrument off and later turn it back on again to proceed with the logging of more samples without losing the measurements already carried out. The maximum number of samples is 99. To reset the calculation, press FUNC until the message ” CLR FUNC ” appears, then use the arrows to select YES and confirm using ENTER. Position the probe in the first measurement point and press HOLD/ to capture the first point value. Repeat the same procedure with all the other points that you feel it is necessary to capture, by pressing HOLD/ each time: the indicator will provide the total number of acquired samples. After recording the first sample or at the end of the capture, press FUNC/ENTER. The MAX, MIN and average values of the chosen quantity, that is, the speed or calculated flow rate on the entire section will be displayed, according to the variable selected at the beginning of the measurement. To end the function, press ESC. Generally, the greater the number of captured measurements (maximum 99) the greater the accuracy of the result obtained.

HD2103

– 15 –

V2.4

Moving average The Duct Calc function provides a spatial averaging of the captured values and therefore compensates the speed differences between one point and another in the duct section. There is also another source of errors due to the variation of the flow in time: that is, the flow is not constant but increases or decreases in the same point. To compensate for this second source of instability, it is possible to get a temporal moving average of the last n measurements capture: with n>1, the displayed value will not be the single captured value but the continuously updated current average of the last n measurements. To set the “n” value, use the AVG TIME SECS menu function: by using the arrows select the desired n value and confirm with ENTER. “n” can be set from 1 (no average) to 99.
Note: the presence of grids or diffusers with tilting fins introduces errors in the measurement of the flow due to the existing turbulence. These are generated because part of the flow, when meeting the obstacle (fin), is slowed down when the rest of the flow proceeds at maximum speed. In this case, to obtain a correct measurement, it is better to temporarily insert a duct after the grid with a length at least double that of the grid’s diagonal and perform the measurements at its end. The area considered for the flow rate calculation will be that of the provisional duct placed between the grid and the probe.

AP471S1 – AP471S2 – AP471S3 – AP471S4 HOT-WIRE WIND SPEED MEASUREMENT PROBES COMPLETE WITH SICRAM MODULE
The AP471S1 and AP471S3 probes measure incident air flows up to 40m/s. The AP471S2, AP471S4 probes are fitted with an omnidirectional sensor allowing measurement of speeds up to 5m/s in any direction of the air flow incident on the probe. The AP471S4 probe is fitted with support base and sensor protection. The wind speed measurement is compensated for according to temperature within the range of 0…+80°C. The probes AP471S1, AP471S2, and AP471S3 measure the environment temperature in the range of -25°C…+80°C; AP471S4 in the range 0°C…+80°C. The AP472S… modules are calibrated in the factory; no calibration is required by the user.
AP471 S1

AP471S4 HD2103

AP471 S3

The AP471S1, S2 and S3 probes are fitted with a cylindrical protection screen that can slide longitudinally over a groove. The screen has two end-of-travel positions that block it in measurement condition (completely low) or rest condition (completely high). To reduce the space occupied when not used, the AP471S4 is supplied with a protection cylinder that can be screwed on the probe’s head.

Proceed with measurement following the instructions provided in this chapter.

Care and maintenance of the probes
The speed sensor of the AP471S… probes is heated and, in the presence of gas vapours, could trigger a fire or explosion. Do not use the probe in the presence of inflammable gases. Ensure that no gas or explosive vapor leakage is present in the measurement spaces. The probe is very delicate and should be handled with extreme care. Even a simple collision, especially of the omnidirectional probes that have an uncovered sensor, could render the probe unusable. After measurement, the sensor set on the probe head must be protected with the supplied metallic screen or threaded cylinder. During use, the AP471S4 omnidirectional probe must be protected with the special metallic grid. During transportation, the sensor must be closed into a cylinder screwed on the end part of the probe. Do not let fingers touch the sensors. Use only alcohol to clean the probe.

AP472S1 – AP472S2 VANE WIND SPEED MEASUREMENT PROBES COMPLETE WITH SICRAM MODULE
The AP472S1 and AP472S2 vane probes measure the incident wind speed and flow rate. The probe AP472S1 measures also the temperature using a thermocouple of type K. On request, they can be fitted with a telescopic rod that eases measurements in areas difficult to reach (for example vents). The probes’ speed and temperature measurement ranges are outlined in the table below:

AP472S1 AP472S2

Speed (m/s) 0.6…25 0.5…20

Temperature (°C)
-25…+80 -25…+80 (working temperature)

—-

Diameter (mm) 100
60

Greater diameters are suitable for flow measurements in the presence of turbulence with mediumlow air speeds (i.e. at the exit of the ducts). Lower diameters are suitable in applications where the probe surface must be much slower than the duct cross section within which the measurement is carried out, i.e. ventilation ducts.

Calibration
The AP472S1 and AP472S2 probes are calibrated in the factory; no calibration is required by the user.

Operation
Where present, extend the telescopic rod to the necessary length paying attention to the cable so that it can slide freely and without strain. Introduce the probe in the air flow being measured, maintaining the arrow at the top of the probe parallel to the flow as indicated in the following figure.

HD2103

V2.4

The probe should be maintained orthogonal to the flow and not tilted in relation to it

OK

NO

The probe is correctly positioned in relation to the air-flow when the value measured is the maximum possible. Proceed with measurement following the instructions provided in this chapter.

Care and maintenance of the probes
The probe performance, mainly at low speeds, largely depends on the very slow friction of the vane on its own axis. In order not to compromise this characteristic, it is recommended that forcing is avoided, as well as blocking or rotating the vane with the fingers, and if possible, avoid inserting it in air flows that could spoil the probe.

To mount the telescopic rod on the probes, unscrew the handle (3) holding the probe body still in the point (1). Screw the rod end on the screw (2). The handle (3) is screwed on the telescopic rod.

WCT index
With particularly cold climatic conditions, the effect of wind speed on the perceived temperature is not negligible: i.e. a temperature of -16°C in presence of wind at 30km/h produces on the human body the same sensation of a -37°C temperature in absence of wind.
When measuring the apparent temperature, the WCT parameter (wind chill equivalent temperature) represents the apparent temperature in presence of cold wind and is determined up to an actual temperature of +10°C; above this limit the display shows an error (ERR). The WCT value is displayed in the main line; the secondary line shows the actual temperature.

DIRECT INPUT Pt100, Pt1000 AND Ni1000 TEMPERATURE PROBES
The instrument accepts the input of Platinum temperature probes with resistances of 100 and 1000, as well as Nickel temperature probes with a 1000 resistance. The Pt100 are connected to 4 wires, the Pt1000 and Ni1000 to 2 wires, with the excitation current chosen minimizing the sensor self-heating effects. All probes with SICRAM module are calibrated in the factory, the 2 or 4-wire probes with direct input are checked for conformity with class A tolerance according to norm IEC751 – BS1904 DIN43760. For the temperature probes without SICRAM module (Pt100 4 wires, Pt1000 and Ni1000) the model configuration is required (please see the description of the Probe Type menu on page 10).
The °C or °F unit of measurement can be chosen for display, printing and logging using the °C/°FESC key.
The probe is detected during turn on, and this cannot be performed when the instrument is already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it off and on.
How to measure The response time for the measurement of the temperature in air is greatly reduced if the air is moving. If the air is still, stir the probe. Please remember that the response times in any case are longer than those for liquid measurements.
The temperature measurement by immersion is carried out by inserting the probe in the liquid for at least 60mm; the sensor is housed in the end part of the probe.
In the temperature measurement by penetration the probe tip must be inserted to a depth of at least 60mm, the sensor is housed in the end part of the probe. When measuring the temperature on frozen blocks it is convenient to use a mechanical tool to bore a cavity in which to insert the tip probe.
In order to perform a correct contact measurement, the measurement surface must be even and smooth, and the probe must be perpendicular to the measurement plane. So as to obtain the correct measurement, the insertion of a drop of oil or heat-conductive paste is useful (do not use water or solvents). This method also improves the response time.
Instructions to connect the TP47 connector for 4 wire Pt100, Pt1000 and Ni1000 probes All Delta Ohm probes are provided with a connector. The HD2103.1 and HD2103.2 instruments also work with 4-wire direct Pt100, Pt1000 and Ni1000 probes manufactured by other producers; the TP47 connector is used for the instrument connection to which the probe’s wires should be welded.

The instructions to connect the Platinum or Nickel probe to the module are provided below. The module is supplied complete with fairlead and gasket for 5mm maximum diameter cables.

WARNINGS AND OPERATING INSTRUCTIONS
1. Do not expose the probes to gases or liquids that could corrode the material of the sensor or the probe itself. Clean the probe carefully after each measurement.
2. Do not bend the probe connectors or force them upward or downward.
3. Do not bend or force the contacts when inserting the probe connector into the instrument.
4. Do not bend, deform or drop the probes, as this could cause irreparable damage.
5. Always select the most suitable probe for your application.
6. Do not use probes in presence of corrosive gases or liquids. The sensor container is made of AISI 316 stainless steel, while the contact probe container is made of AISI 316 stainless steel plus silver. Avoid contact between the probe surface and any sticky surface or substance that could corrode or damage it.
7. Above 400°C and below 40°C, avoid violent blows or thermal shocks to Platinum temperature probes as this could cause irreparable damage.
8. To obtain reliable temperature measurements, temperature variations that are too rapid must be avoided.
9. Temperature probes for surface measurements (contact probes) must be held perpendicular against the surface. Apply oil or heat-conductive paste between the surface and the probe in order to improve contact and reduce reading time. Whatever you do, do not use water or solvent for this purpose. A contact measurement is always very hard to perform. It has high levels of uncertainty and depends on the ability of the operator.
10. Temperature measurements on non-metal surfaces usually require a great deal of time due to the low heat conductivity of non-metal materials.
11. Probes are not insulated from their external casing; be very careful not to come into contact with live parts (above 48V). This could be extremely dangerous for the instrument as well as for the operator, who could be electrocuted.
12. Avoid taking measurements in presence of high frequency sources, microwave ovens or large magnetic fields; results may not be very reliable.
13. Clean the probe carefully after use.
14. The instrument is water resistant and IP66, but should not be immersed in water without closing the free connectors using caps. The probe connectors must be fitted with sealing gaskets. Should the instrument fall into the water, check for any water infiltration. Gently handle the instrument in such a way as to prevent any water infiltration from the connectors’ side.

STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER
The HD2103.1 and HD2103.2 instruments can be connected to a personal computer via an RS232C serial port or USB 2.0 port, and exchange data and information through the DeltaLog9 software running in a Windows operating environment. Both models can send in real time input measured values directly to a PC, through the PRINT function; the HD2103.2 can also store the values measured by using the Logging function (LOG key) in its internal memory. If necessary, the data stored in the memory can be transferred to a PC later.

THE LOGGING FUNCTION – ONLY FOR HD2103.2
The Logging function allows the recording up to 38,000 measurements registered by the probe connected to the input. The time interval between two consecutive measurements can be set from 1 second to 1 hour. The logging starts by pressing the LOG key and ends by pressing the same key again: the data memorized in this way form a continuous block of data.
See the description of the menu item on page 10.
If the automatic turning off option between two recordings (menu >> Sleep_Mode_LOG) is enabled, upon pressing the LOG key the instrument logs the first data and turns off (the LOG ON indication periodically appears on the display to indicate that the Logging function is active). 15 seconds before the next logging instant, it turns on again to capture the new sample, and then turns off.
The data stored in the memory can be transferred to a PC using the DUMP LOG command: MENU >> LOG. During data transfer the display shows the message DUMP; to stop the data transfer press ESC on the instrument or on the PC.
CLEARING THE MEMORY – ONLY FOR HD2103.2
To clear the memory, use the Erase Log function (MENU >> SERIAL). The instrument starts clearing the internal memory; at the end of the operation, it goes back to normal display.
NOTES: · Data transfer does not cause the memory to be erased; the operation can be repeated as many
times as required. · The logged data remain in the memory apart from the batteries charge conditions. · In order to print the data to a parallel interface printer, you must use a parallel-serial adaptor (not
supplied). · The direct connection between instrument and printer via a USB connector does not work. · Some keys are disabled during logging. The following keys work: HOLD, FUNC (Max-Min-
Avg) and SERIAL. · Pressing the HOLD, REL and FUNC keys has no effect on the logged data if these keys are
pressed after starting the recording, otherwise the following is valid. · The recording started with the display in HOLD mode proceeds normally with the actual
measured values (that is, not in “HOLD” mode). Only the display is frozen to the values present when the HOLD key was pressed. · The same is true for the Max-Min-Avg function. · If the logging is started when the display is in REL mode, the relative values are logged. · It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the same time.

HD2103

V2.4

THE PRINT FUNCTION
The PRINT function sends the measurements taken in real time by the instrument inputs directly to a PC or a printer. Print data units of measurements are the same as those used on the display. The function is started by pressing SERIAL. The time interval between two consecutive prints can be set from 1 second to 1 hour (please see the Print and log interval menu item on page 10). If the print interval is equal to 0, by pressing SERIAL the single data is sent to the connected device. If the print interval is higher than 0, the data transfer continues until the operator stops it by pressing SERIAL again.
The PRINT function works with a standard serial communication program (e.g. Hyperterminal) only through the RS232 serial port of the instrument, using the cable HD2110CSNM or the cable C.206.
Connect the HD40.1 printer using cable HD2110CSNM.
NOTES:
· The print out is formatted across 24 columns. · Some keys are disabled during serial transmission. The following keys work: ON/OFF, HOLD,
FUNC (Max-Min-Avg) and LOG. · Pressing the HOLD, REL and FUNC keys has no effect on the printed data if these keys are
pressed after starting the printing, otherwise the following is valid. · The transfer started with the display in HOLD mode proceeds normally with the actual
measured values (that is, not in “HOLD” mode). Only the display is frozen to the values present when the HOLD key was pressed. · The same is true for the Max-Min-Avg function. · If the serial transfer is started when the display is in REL mode, the relative values are transferred. · It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the same time.
