2.4 Warnings and Caution Notices
WARNING: PRESSURE! Pressure gases are potentially hazardous. Energy stored in these gases can be
released suddenly and with extreme force. Pressure systems should be assembled and operated only
by personnel who have been trained in proper safety practices.
Do not disconnect any pressure connection of the Traqc-8 DPC when a leak test of any kind is
processing. Physical injury may exceed when process connections will be disconnected, caused by
the expanding gas.
CAUTION: Pressure testing with compressed gases can lead to additional risks due to release of
stored energy (e.g. burst of system, flying objects). Please take appropriate measures (e.g. shielding,
use of personal protective equipment (PPE)) to prevent hazardous situations which could result in
human injuries.
WARNING: POSSIBLE INJURY! The tubing, valves and other apparatus attached to the instrument
must be adequate for the maximum pressure which will be applied, otherwise physical injury to the
operator or bystanders is possible.
CAUTION: Use proper pressure medium. Use only clean, dry gas. This instrument is not designed for
oxygen use.
WARNING: NOT EXPLOSION PROOF! Use of this instrument in an area requiring devices rated as
intrinsically safe is not recommended.
WARNING: Detachable main power supply cord with inadequate ratings should not be used.
WARNING: It is the responsibility to the operator to ensure that pressure in circuits connected to the
Traqc-8 DPC will never exceed their safe working pressure. In the event that the maximum safe
working pressure of a circuit / system to be tested is lower than the maximum obtainable output
pressure of the Traqc-8 DPC, the operator who will perform the tests must be instructed in advance
regarding the maximum safe working pressure of the external circuit.
Depending on the volume and pressure in the external circuit the risks for humans and material can
be very high. For that reason the end user must ensure that maximum pressure levels for each circuit
are established as set forth by law. (European directive 2014/68/EU or similar guidelines/obligations
are specified and applicable in the country of use.)
Because of the potential risk for human beings in the vicinity of systems/circuits under pressure, the
end user must ensure that risks are kept to the minimum by fencing, warning, forbidding passage or
access to the area for as long as the risk exists.
Do not connect the voltages higher than specified in the specifications to the PDT Tool. If higher
voltages are connected, the interface control may be damaged.

3.2 Operating Instructions
The TRAQC-8 DPC is a differential pressure calibrator with a maximum of 75 bar line pressure and is designed
on customer request. The calibrator includes a high pressure reducer which has to be fed by an external
pressure source of maximal 200 bar (refill connection) or by the internal gas bottles. On the pressure outlet
of the Pressure control valve are a Supply valve, and a high precision volume controller for fine adjustment
of the test pressure.
3.2.1 Preparations before bring on pressure to test connections
Before set up pressure to the calibrator, ensure that:
The Mode selector valve must be in position “Equalize”
The sensing element + and –are interconnected, so pressure is equal at both sides of
the pressure sensor. Before switching the Mode selector valve to position “Measure”,
make sure that both pressures at Test + and Test –are within the measure range of the
instrument
When the calibrator will be used without external pressure supply, ensure that the gas
bottles are filled to maximum to ensure high pressure during the test procedure;
See 2.3 for instructions for refilling the gas bottles
When the calibrator will be used without external power supply, ensure that the battery
of the calibrator is charged to maximum to ensure power during the test procedure.
See 2.6 for instructions how to charge the battery
The Heise volume controller which is needed to set a differential pressure, is turned to
the middle of the range
(30turns clock wise from fully clockwise on)
The Pressure control valve is turned fully counter clockwise
The Supply valve is turned fully counter clockwise
The Balance valve of the Heise volume controller must be set into vent mode (pull)
The Relief (vent) valve is turned fully clockwise

3.2.2 Precautions before bring on pressure to test connections
Failure to comply to the measuring range will destroy the measuring element. Ensuring pressures are within
specified ranges is the responsibility of the operator.
At the attachment you will find the pneumatic schematics of this instrument and the manual of the Heise
volume controller.
Please read the pneumatic schematics of this instrument carefully before operating this instrument!
Wrong operating of this instrument will cause serious damage of the differential pressure sensor!
The valves T1700 have a soft seat and a tight shut-off. It is not necessary to close them with
excess force. See §7.1.4 for instructions.
3.2.3 Bring on pressure to test connections
If all preparations as noticed at 3.2.1 have been carried out, the test procedure can be start:
If available, connect the power connection of the calibrator to an external power supply
If available, connect the refilling connection of the calibrator to an external pressure
supply, maximum 200 bar
Push the power button to turn on the calibrator
Connect the test connections of the calibrator to the instrument to be tested
Turn the Bottle shut off valve counter clockwise or open the external pressure supply to
bring on pressure to the system
Turn the Pressure control valve clock wise, till the test pressure is reached at
Manometer 1
Now close the Supply valve fully clockwise to ensure no pressure will leak out of the test
circuit
During the test, the Supply valve must be closed!
If during the test the Supply valve will be opened, probably the pressure sensor will be damaged
so it has to be replaced!
The Balance valve of the Heise volume controller must be set into Test mode (push)
Turn the Mode selector valve to ‘Measure’
During the test, the Mode selector valve must stay in the ‘Measure’-position!
If during the test the Mode selector valve will be set into Equalize-position, then the pressure
sensor possibly will be damaged so it has to be replaced!
Now a differential pressure between Test + connection and Test –connection can be set.
Therefore, turn the Heise volume controller clock wise to bring on positive differential
pressure. The differential pressure can be read at the display
The range of the differential pressure sensor is from 0 to 1000 mbar above line pressure.
To fine tune the differential pressure you must use the Heise volume controller
Do not use the Relief valve to release pressure during a test. When you do, probably the
differential pressure will lower too fast and too low, which may cause such a low pressure that the
pressure sensor will be damaged so it has to be replaced!
Let stabilize the test pressure before taking measurement point

3.2.4 Ending a differential pressure test
If a differential pressure test is ended, you have to follow up the next procedure to set the calibrator into the
safe mode.
When the operator will not follow up the next procedure, there wil be a risk that the pressure
sensor will be damaged so it has to be replaced!
With the Heise volume controller, minimize the differential pressure within 200 mbar
Turn the Mode selector valve to ‘Equalize’
Close the Bottle shut off valve or shut off the external pressure supply
Turn the Pressure control valve fully counter clockwise
Set the Balance valve of the Heise volume controller to Vent mode (pull)
Release the test pressure of the calibrator by slowly opening the Relief valve
Turn the Pressure control valve fully counter clockwise

3.3 Instructions for refilling the gas bottles
Refilling the gas bottles can be done by using either another bottle or a high pressure compressor. The
maximal refilling pressure is 200 and the capacity is 2 liters.
When the refilling is done from another bottle, the included RU 3 connector can be used.
The refilling by a high pressure compressor can be made by a direct connection.
Turn the Selection valve to “Equalize”
Turn the Relief (vent) valve fully counter clockwise
Close both the Bottle shut off valve and the Supply valve by turning these fully clockwise
Turn the “Pressure control valve” fully counter clockwise
Connect the filling hose to the “Refill connection’
Set the compressor or the external bottle to a maximum pressure of 200 bar
Slowly open the “Bottle shut off valve”. The gas bottles now will be refilled and the pressure of the
bottles can be checked on the Manometer 3
Slowly refill the gas bottle. A quick refilling will increase the temperature. An increase in
temperature will affect the pressure by increasing it. This means no optimal filling will be obtained;
Close the gas “Bottle shut off valve” and shut-off the compressor
To get the filling hose free of pressure:
oTurn the Pressure control valve 4 turns clockwise

3.6 Power Supply
The unit is equipped with an internal not removable Li-Ion battery. The charging of the batteries is fully
automated. The TRAQC-8 DPC is charged when its connected to the mains power supply. Charging will start
as soon as the instrument is connected to the mains supply.
The instrument can be used while charging the battery, but the required charging time could be increased
depending upon the selected operating mode of the instrument.
3.6.1 Battery status display
The status of the battery is displayed with a battery symbol on the lcd display when the instrument is
switched on.
During charging the battery symbol will be filled with lines until it is completely filled and when all lines are
drawn the symbol will be cleared and starts filling again.
When charging is completed the symbol will be completely filled and remains filled as long as the instrument
is connected to the mains supply.
3.6.2 Operating time indication
The instrument has an internal ‘gas gauge’ to measure the battery capacity, this gas gauge is automatically
updated when the battery is charged or discharged and is used to indicate the battery charging state and
remaining operating time.
The charging state of the battery is indicated with lines in the battery symbol.
When the battery is full all lines in the battery are drawn and when the instrument is operating on the
battery less lines will be shown.
The number of lines shown in the battery is a rough indication of the remaining battery capacity.
When the remaining operating time drops below 3 hours the remaining time will be shown next to the
battery symbol
The operating time of the instrument on the indicated charge state depends upon the usage of the
instrument, Operating modes where the electrical outputs are used draw more current from the
battery and therefore shorten the operating time more than other modes.
3.6.3 Instrument charging before storage
The instrument should not be stored for longer periods with an empty battery, doing so will reduce the
capacity of the battery and shorten the battery life.
When the instrument must be stored the battery should be charged to at least 50% of its indicated capacity.
3.6.4 Battery Replacement
The battery can only be replaced by Tradinco or a Tradinco approved repair facility.

3.7 Power On/Off
The TRAQC-8 DPC is switched on and off by pressing the on/off key. The TRAQC-8 DPC will go through a short
startup self-check routine. During that routine the display shows the current firmware. After completing the
startup procedures the device switches into the measuring mode and displays the measured value(s), and the
measuring unit(s) from last time. When turning off the device, the display shows ‘Shutting Down’.
If the calibrator needs to be recalibrated at short notice, a message with the date that the instrument
should be re-calibrated is displayed for several seconds before the startup procedure continues. If the
recalibration date has expired a message is displayed as a warning. By pressing ‘ENTER’ key (F1) the
start-up procedure is continued.
3.8 Menu
The main menu is accessed by pressing the ‘MENU’ key (F1). On top in the
display the current location in the menu structure is shown.
Some of the functions in the menu structure are for optional
functionality of the instruments. Therefore it is possible the
TRAQC-8 DPC included with this manual has less functions than
explained in this user manual.

3.9 Zeroing
To zero an input signal press ‘ZERO’ key (F2) in the “measuring mode”
display. The menu shows the different inputs that can be zeroed, consisting
of pressure inputs and the electrical inputs. Select the desired input using
the ‘ARROW’ keys.
By pressing the ‘BACK’ key (F3) the zeroing procedure is stopped
without making modifications.
By pressing ‘ENTER’ key (F1) the zeroing procedure is continued and
there is asked to confirm the zeroing procedure after which the
calibrator returns to measuring mode.
When zeroing the ‘Pressure Input’, ensure that the pressure ports are open to atmospheric pressure.
The TRAQC-8 DPC comes standard with a quick connect coupling with
integraded shut off valve. This can be opened by:
Connect/insert the other half of the coupling to the pressure
coupling (-port) of the TRAQC-8 DPC
Connect one side of a pressure hose to the pressure coupling (-port)
of the TRAQC-8 DPC and leave the other side of the hose
unconnected.
With these procedures the pressure in the system of the TRAQC-8 DPC can
get equal with the atmospheric pressure.
To zero another test pressure and/or electrical signal, first generate the
required test signal (tare value) and carry out the above-described zeroing procedure. The test value displayed
is the difference between the actual test value and the entered tare value.
3.10 Selecting Pressure Units
When in “measuring mode” screen press the ‘UNIT’ key (F3) to change the unit.
Use the ‘ARROW’ keys to select the desired unit and press ‘ENTER’ key (F1)
to confirm and go back to “measuring mode”.
The following units can be selected:
bar kgf/cm2inHg
mbar mmH2O torr
Pa cmH20 %
hPa mH2O mSeaw
kPa inH20
MPa ftH2O
psi mmHg
Not all operating modes that support pressure measurement have the ‘UNIT’ key due to lcd and
keyboard space limitations. The pressure unit can also be selected via the menu, press the ‘F1’key and
select the ‘pressure setup’ and then ‘pressure unit’ for these modes.
3.11 Pressure Range
Depending upon the configuration of the instrument the TRAQC-8 DPC can be equipped with one, two or
three pressure sensors.

User Manual
TRAQC-8 DPC
TRAQC-8 DPC 11/2016 EN Rev.3 Sheet 20
In instruments with two or three sensors the user can select the pressure range by pressing the ‘UP’-or
‘DOWN’, ‘ARROW’ key in “measuring mode”
Not all operating modes support the ‘UP’ or ‘DOWN’ keys for selecting the pressure range. To change
the pressure range you can also select the option ‘pressure range’ in the ‘pressure setup’ menu.
Depending upon the operating mode the range selection menu offers different possibilities.
3.11.1 Electric in- or output active
When the instrument is also measuring an electrical signal only one pressure
input can be used. By using the ‘ARROW’ keys, select the desired pressure
sensor and press ‘ENTER’ key (F1) to confirm, press the ‘BACK’ key (F3) to
cancel.
3.11.2 Electric in- or output not active
When the electrical input are not active an instrument with more than one
sensor can show the measured value of two pressure inputs.
In this situation the pressure range menu can be used to switch the individual
ranges on or off.
3.11.3 Selecting Pressure sensor Auto ranging
The TRAQC-8 DPC can also be equipped with two pressure ranges and one pressure connection for
measuring test pressure. The TRAQC-8 DPC is configured to automatically switch the measuring range.
When the test pressure exceeds 101% of the low measuring range the TRAQC-8 DPC will automatically
switch from the low pressure range to the high pressure range. If the test pressure is lower than 99% of the
low pressure range it will automatically switch back to the low pressure range.
This auto ranging feature will be automatically be enabled when the TRAQC-8 DPC is switched on.
Auto ranging instruments cannot display the measured value from both sensors at the same time, only the
pressure from the selected sensor will be displayed.
