DESCRIPTION OF THE FUNCTIONS

The keyboard of the RTD Thermometer Model HD2307.0 is composed of double- function keys. The function on the key is the “main function”, while the one above the key is the “secondary function”. When the instrument is in standard measurement mode, the main function is active. In the menu, the secondary function is enabled; press the DATA+UNIT keys together to open the menu. 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 and AUTO-OFF

This key has two functions:

• ON/OFF: press this key to turn the instrument on and off.
  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.

• AUTO/OFF: the AutoPowerOff function can be disabled by simultaneously pressing this key and the “HOLD” key when turning the instrument on. During turning on, should no probes be connected, the “NO_PRBE_SER_NUM” message is displayed in the line for 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 data are captured upon turning the instrument on, it is necessary to turn it off and on again.
  Caution! Replace the probes when the instrument is off.

Disabling of the 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. Press simultaneously the ON/OFF key and the HOLD key to disable this function. In this case, remember to turn the instrument off using the ON/OFF key: disabling of the automatic turning off is shown by the blinking battery symbol.

DATA/ENTER key

The DATA key is used for the following functions:

• DATA: during normal measurement, by pressing this key once the maximum (MAX) value of the measurements captured by the probe connected to the instrument is displayed, updating it with the acquisition of new samples;

  • by pressing this key again the minimum (MIN) value is displayed;
  • by pressing this key a third time the average (AVG) value is displayed.
    The acquisition frequency is once a second. The MAX, MIN and AVG values remain in the memory until the instrument is on, even after exiting the DATA display function. When the instrument is off, the previously memorized data are cleared. Upon turning on, the instrument automatically starts memorizing the MAX, MIN and AVG values. To reset the previous values and start with a new measurement session, press CLR until the FUNC_CLRD message appears.

• ENTER: once the MENU has been opened with the DATA+UNIT keys, the DATA key will perform the ENTER function and the MENU can be browsed and the displayed parameter confirmed.

THE PROGRAMMING MENU

To access to the menu press simultaneously the following keys:

The items to be set are listed in this order:

1. Probe type: the “RTD_PRBE_TYPE” message is displayed 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:

   • temperature probes Pt100 complete with SICRAM module

   • direct 4-wire Pt100 probes complete with TP47 module

   • direct 3-wire Pt100 probes complete with TP47 module

   • 2 or 4-wire Pt1000 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 as AUTO and cannot be modified by the user.
     Upon turning on the direct 4 wire Pt100, direct 3 wire Pt100, and 2 wire Pt1000 temperature probes display the “NO_PRBE_SER_NUM” ( no serial number of the connected probe) message; in this case the probe type must be entered manually. Select Probe type using the MENU key and then select the type of probe with the arrow keys; confirm using ENTER.

   • use the UP BUTTON  and DOWN BUTTON arrows (respectively located above the HOLD and REL keys) to modify the type of probe;

   • press DATA/ENTER to confirm the modification;
   • press CLR/ESC to cancel the modification;
   • to exit the menu, press the UNIT/MENU key again.

PROBES AND MEASUREMENTS

The instrument works with temperature probes fitted with SICRAM module (with a Platinum Pt100 sensor with 100Ω resistance) or with direct 4 wire Pt100, 3 wire Pt100, or 2 wire Pt1000 sensor. The excitation current was chosen in order to minimize the sensor self-heating effects. The SICRAM module 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 instrument to recognize the type of probe connected and to read its calibration information. The probes with SICRAM module are automatically detected, while the direct probes must be set up in the Probe type menu item (please see chapter ‘The programming menu’). 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.

TEMPERATURE MEASUREMENT

In all versions the temperature sensor is housed in the end part of the probe. 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. The response times 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 60 mm; 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 60 mm, the sensor is housed in the end part of the probe.

NOTE:
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 between the surface and the probe is useful (do not use water or solvents). This method also improves the response time. The °C or °F unit of measurement can be chosen using the UNIT/MENU key.

CALIBRATION OF THE PROBE

To calibrate the probes correctly, a knowledge of and abiding by the physical phenomena on which the measurement is based is fundamental: this is the reason why it is recommended to abide by what is reported below carefully, and only to perform new calibrations if technically proficient and using the suitable equipment. The sensor is calibrated in the factory and the Callendar Van Dusen parameters are recorded in the SICRAM module. The probes with direct input are checked for conformity with class A tolerance according to norm IEC751 – BS1904 – DIN43760. The instrument is provided with the FACT (factory) calibration. The user is also able to perform a USER calibration of instrument+probe. The calibration information is saved in the instrument memory and not in the probe. The same correction is applied to any probe connected to the input: therefore, the “USER calibration” should only be used with the probe used for calibration and not with other probes. To pass from the user to the factory calibration and back, proceed as follows:

• press simultaneously UNIT/MENU and DATA/ENTER to open the menu:
• press ENTER until the menu item “CAL_MODE” is selected.
• use the UP BUTTON and  DOWN BUTTON  arrows (respectively located above the HOLD and REL keys) to select the type of calibration;
• confirm by pressing DATA/ENTER.

CALIBRATION SEQUENCE – INSTRUMENT ON LINE WITH THE PROBE(S):
The calibration can be carried out on one or two points that should differ by at least 10°C and be included in the probe functioning range.

1. Insert the probe into a thermostatic bath, the temperature of which is precisely known from a reading taken on a sample reference thermometer. Wait for the measurement to stabilize.
2. Press contemporarily UNIT/MENU and DATA/ENTER.
3. Press DATA/ENTER.
4. Use the UP BUTTON and DOWN BUTTON arrows (respectively located above the HOLD and REL keys) to select the USER calibration;
5. Confirm with DATA/ENTER.
6. The “SEL_MEAS_1/2” message is displayed in the comment line.
7. Use the UP BUTTON and DOWN BUTTON arrows to select “1” (first calibration point).

20. To exit the procedure, select “0” using the UP BUTTON and DOWN BUTTON arrows and press ENTER.

CONNECTING THE TP47 CONNECTOR FOR THE 3 AND 4 WIRE PT100 AND 2 OR 4- WIRE PT1000 PROBES:
Where present, extend the telescopic rod to the necessary length paying attention to the cable so that All probes produced by Delta OHM are provided with a connector. The Platinum Thermometer Model HD2307.0 also work with direct 3 and 4-wire Pt100 and 2 or 4-wire Pt1000 probes manufactured by other producers; for the instrument, connection is prescribed the TP47 connector to which the probe’s wires should be welded.

The instructions to connect the Platinum probe to the TP47 module are provided below. The TP47 module is supplied complete with fairlead and gasket for 5 mm maximum diameter cables. Do the following to open the module and connect a probe:

1. unscrew the fairlead;

2. extract the gasket;

3. remove the label using a cutter;

4. unscrew the ring on the opposite side as illustrated in the figure:

5. open the two module shells: the printed circuit to which the probe must be connected is housed inside. On the left there are the 1…4 points on which the sensor wires must be welded. The JP1…JP4 jumpers are in the center of the board. These must be closed with a tin bead for some type of sensors:
   Caution! Before welding, pass the probe cable through the fairlead and gasket.

6. Weld the wires as shown in the table:
   Ensure the welds are clean and perfect.

7. Once the welding operation is complete, close the two shells;

8. Insert the gasket in the module;

9. Screw the fairlead and the ring.

10. At the other end of the module, enter the ring with the O-Ring as indicated in the picture.

11. Make sure the cable is not twisted while you are screwing the fairlead. Now the probe is ready.

DIRECT CONNECTION OF 4 WIRE PT100 SENSORS

4 wire Pt100 sensors can be soldered directly to the pins of the flying female connector without making use of the TP47 board. The 4 wires of the Pt100 sensors have to be soldered as indicated in the figure on the left. In order to use this type of probe it is necessary to set up the menu item “Probe Type”. The P100 probe is recognized upon turning on the instrument: connect the probe when the instrument is switched off and then turn it on.

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 the temperature 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 from AISI 316 stainless steel plus silver. Avoid contact between the probe surface and any sticky surface or product 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 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. The sensor is not insulated from its 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 IP67, but should not be immersed in water. 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.
