GENERAL CHARACTERISTICS

The HD2304.0 Manometer – Thermometer is a portable instrument that allows
measurement of absolute, relative and differential pressure, and temperature.

The PP471 electronic module is used to measure the pressure. The module works as an interface between the instrument and the TP704 and TP705 series Delta Ohm probes.
The temperature is detected using immersion, penetration, contact or air Pt100 probes with SICRAM module, or direct 4 wire Pt100 probes.

The probes are fitted with the SICRAM automatic detection module, with the factory
calibration settings already being memorized inside.

The units of measurement for the measurable quantities are:

Pa (Pascal)
hPa (hectopascal)
kPa (kilopascal)
mbar (millibar)
bar (bar)
atm (atmosphere)
mmHg (millimeter of mercury)
mmH2O (millimeter of water)
kgf/cm² (kilogram-force/square centimeter)
PSI
inch Hg (inch of mercury)
inchH2O (inch of water)
°C/°F

Using the MAX, MIN and AVG function of this instrument respectively obtains the
maximum, minimum or average values.

Other available functions are:

the relative measurement REL;
the HOLD function;
the automatic turning off which can also be disabled.

DESCRIPTION OF THE FUNCTIONS

The keyboard of the HD2304.0 Manometer – Thermometer 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.
Once the Settings Menu has been opened, by pressing simultaneously the DATA+UNIT keys, 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 and AUTO/OFF key**

This key has two functions:

ON/OFF: to turn the instrument on press ON, to turn it off press 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. The following is displayed:

AUTO/OFF: the Auto Power Off 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, while the “ERR”
message is shown in the central part of the display. When the probe is inserted into a
functioning instrument, the “NEW_PROB_DET” (New probe detected) message
appears, while the “ERR” message is shown in the central part of the display, and a
sequence of “beeps” is simultaneously issued. 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 Auto Power Off 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.

CLR/ESC key

The CLR key has two functions:

CLEAR (CLR): allows to reset the maximum (MAX), minimum (MIN) and
average (AVG) value of the captured measurements;
ESC: once the MENU has been opened with the DATA+UNIT keys, the CLR
key will allow to cancel the parameters set using the and arrows.

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 and 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 calculation 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
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. During electrode calibration, it allows to
decrease the nominal buffer value.

HOLD/ key

The HOLD key is used for the following functions:

• HOLD: by pressing this key the current measurement is frozen and the “HOLD”
message will appear in the upper left-hand corner of the display. To return to
the current measurement, press the key again.
• : once the MENU has been opened with the DATA+MENU key, the key will
allow to increase the value of the selected parameter.

Pressed together with the ON/OFF key, during turn on, the Auto Power Off function is disabled (see the description of the ON/OFF key).

UNIT/MENU key

The following probes can be connected to the input:

TP704 and TP705 pressure probes combined with the PP471 module: the type of probe (i.e. if the PP471 module and the TP704-2BAI probe (2 bar absolute) are connected) is shown in the central part of the display. In the main line “2” is displayed, which indicates the sensor’s bottom scale. The unit of measurement “bAr” and the sensor characteristic “Abs” (absolute) are displayed alternately in the secondary line;
temperature probes “Pt100” complete with SICRAM module: the “Auto”
message is displayed in the central part of the display;
direct 4 wire “Pt100” temperature probes: in this case, the “100Pt_4u”
message is displayed.

NOTE: Upon turning on the instrument automatically detects the probes fitted with
SICRAM module: the type of probe is configured by the instrument and cannot be
modified by the user.
If direct 4 wire “Pt100” probes that are not manufactured by “Delta OHM” are
connected to the instrument, the NO_PRBE_SER_NUM message is displayed .

use the and arrows (respectively located above the HOLD and REL keys) to
modify the displayed value;
press DATA/ENTER to confirm the modification and go onto the next item;
press CLR/ESC to cancel the modification;
to exit the menu, press the UNIT/MENU key again.

PROBES AND MEASUREMENTS

The instrument measures absolute, relative and differential pressure using the PP471
SICRAM module and the TP704 and TP705 series probes. It also measures the
temperature with a Pt100 sensor with SICRAM module or with direct 4 wire Pt100
probes.
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 are 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.
The probes fitted with SICRAM module are calibrated in the factory; no calibration is
required by the user.

PP471 MODULE FOR PRESSURE MEASUREMENT

The PP471 module acts as an interface between the TP704 and TP705 series Delta
OHM probes and the instrument. The TP704 series pressure probes have a 1/4″ BSP
threaded male connection, and must be screwed into the system using the necessary
sealing gaskets. The TP705 series have two Ø5 connections where the suitable tubes
are inserted in order to perform the desired measurement.

Caution! Please pay careful attention to the joint pressure sealing; use suitable
gaskets and joints. The threaded connection is protected by a plastic cap. Put it back
after use as it protects the pressure cell from foreign bodies.

IMPORTANT! Ensure the probe’s bottom scale is higher than the pressure that will be measured. In case this value is unknown, start by using higher capacity probes.

For every pressure probe a range of overload pressure and a burst pressure are declared: pressures in the range of overload pressure don’t cause the break of the sensor but the declared accuracy can be overcome. Pressure over the stated burst pressure may break the sensor. The application of higher pressures than the overload pressure limit, although lower than the burst pressure, may produce permanent damage to the probe (e.g. offset shift). Never exceed the stated burst pressure (see Technical Characteristics of the probes at page xx)

Upon turning on the instrument automatically detects the PP471 module. The probe’s
type (absolute, relative or differential) and bottom scale value are detected even
when the instrument is on (see chapter 3).
To change the instantaneous or peak value unit of measurement, press UNIT. The
following units of measurement are available:
Pa, hPa, kPa, mbar, bar, atm, mmHg, mmH2O, kgf/cm2, PSI, inch Hg, inchH2O.
Some units of measurement require a degree of multiplication:

the “-3” symbol indicates the displayed value must be divided by 1,000;
the “3” and “6” symbols indicate the displayed value must be multiplied
respectively by 1,000 or by 1,000,000.

The instrument does not automatically detect the probes which are not fitted with
SICRAM module.

Pt100 TEMPERATURE PROBES

The instrument accepts the input of platinum temperature probes with resistances of
100Ω (Pt100).
The Pt100 sensors are connected to 4 wires; the excitation current was chosen in
order to minimize the sensor self-heating effects.
All probes with module are calibrated in the factory; no calibration is usually required
by the user.
The °C or °F unit of measurement can be chosen using the UNIT key.

TEMPERATURE MEASUREMENT

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 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.

CONNECTING THE TP47 CONNECTOR

All probes produced by Delta Ohm are provided with a connector.
The HD2304 also work with direct 4 wire Pt100 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:

unscrew the fairlead;
extract the gasket;
remove the label using a cutter;
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.

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” as described at page 10.

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

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. Some pressure probe models are suitable for measurement of non-corrosive gases or air and dry and not liquid only: check the membrane compatibility with the plant fluid.
Do not bend the probe connectors or force them upward or downward. Do not bend or force the contacts when inserting the probe connector into the instrument.
Do not bend, deform or drop the probes, as this could cause irreparable damage.
Always select the most suitable probe for your application.
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.
Above 400°C and below –40°C, avoid violent blows or thermal shocks to Platinum temperature probes as this could cause irreparable damage.
To obtain reliable measurements, temperature variations that are too rapid must be avoided.
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.
Temperature measurements on non-metal surfaces usually require a great deal of
time due to the low heat conductivity of non-metal materials.
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.
Avoid taking measurements in presence of high frequency sources, microwave
ovens or large magnetic fields; results may not be very reliable.
Clean the probe carefully after use. Clean the probe pressure chamber carefully.
Avoid deposits or incrustations left by the fluid coming into contact with the
membrane, as with time this could cause measurement errors.
Avoid inserting nails or spikes into the pressure chamber as the membrane could be unintentionally torn.
In order to fix the probes, use a suitable fixed wrench, and possibly sealing gaskets.
Great attention must be paid while installing the probes in containers and tubes under pressure. Also pay attention to the probes’ bottom scale. In addition to the irreparable damage, it can even cause serious physical damage to both the operator and things. Before the probe a stop valve should always be present. Ensure that the plant is not subject to abnormal or unexpected depressed fluid fluctuations.
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.

WARRANTY
Delta OHM is required to respond to the “factory warranty” only in those cases provided by Legislative Decree 6 September 2005 – n. 206. Each instrument is sold after rigorous inspections; if any manufacturing defect is found, it is necessary to contact the distributor where the instrument was purchased from. During the warranty period (24 months from the date of invoice) any manufacturing defects found will be repaired free of charge. Misuse, wear, neglect, lack or inefficient maintenance as well as theft and damage during transport are excluded. Warranty does not apply if changes, tampering or unauthorized repairs are made on the product. Solutions, probes, electrodes and microphones are not guaranteed as the improper use, even for a few
minutes, may cause irreparable damages.

Delta OHM repairs the products that show defects of construction in accordance with the terms and conditions of warranty included in the manual of the product. For any dispute, the competent court is the Court of Padua. The Italian law and the “Convention on Contracts for the International Sales of Goods” apply.

TECHNICAL INFORMATION

The quality level of our instruments is the result of the continuous product development. This may lead to differences between the information reported in the manual and the instrument you have purchased. In case of discrepancies and/or inconsistencies, please write to [email protected]. Delta OHM reserves the right to change technical specifications and dimensions to fit the product requirements without prior notice.

DISPOSAL INFORMATION

Electrical and electronic equipment marked with specific symbol in compliance with 2012/19/EU Directive must be disposed of separately from household waste. European users can hand them over to the dealer or to the manufacturer when purchasing a new electrical and electronic equipment, or to a WEEE collection point designated by local authorities. Illegal disposal is punished by law.

Disposing of electrical and electronic equipment separately from normal waste helps to preserve natural resources and allows materials to be recycled in an environmentally friendly way without risks to human health.
