1. General
1.1 Introduction
The Traqc-2 PC is a portable calibration instrument to perform calibrations on site:
•by reducing pressure from an external circuit, by means of a connected pressure supply (max. 10 bar). After this,
the applied pressure can be read on the display.
•by directly measuring the pressure of a connected external circuit (max. 10 bar).
Also a leak test can be performed with the Traqc-2 PC. The built-in pressure cell has been calibrated to confirm that
the measured value is within the accuracy described in the specifications.

2. Safety symbols, notices and warnings
This warning symbol indicates danger for the system and material if the respective safety precautions are
not taken, or indicates that danger of injury for persons and the environment and/or considerable material
damage (mortal danger, danger of injury) will occur if the respective safety precautions are not taken.
This warning symbol indicates danger by explosion for the system and material and the operator and
bystanders if the respective safety precautions are not taken.
This notice symbol does not indicate safety notices but information for a better understanding of the facts.
2.1 Responsible use of the Traqc-2 PC
To ensure safety, the operator must make sure that the following conditions are met:
•The system is used properly, no dangerous media are used and that all technical specifications are observed;
•The system is in perfect operating condition;
•The operation manual is legible and accessible to the user at the system’s location;
•The system is operated, serviced and repaired only by authorized and qualified personnel;
•The user receives instruction on industrial safety and environmental protection, and is knowledgeable of all
operating instructions and safety notices relevant to the current procedure.
2.2 General safety instructions
The system should be operated only by trained personnel who are familiar with this manual and the
operation of the instrument.
The battery of the Traqc-2 PC should be charged regularly. Only use the supplied USB cable for this, which
may be connected to a USB charging point that delivers a maximum of 500 mA/hr in order to prevent
overloading the internal electronics.
A condition for trouble-free and safe operation of this system is proper transport, proper storage,
installation, assembly and proper use as well as careful operation and maintenance.
Any operation not described in the following instructions should be prohibited. The system must be
handled with care required for an electronic precision instrument (protect from humidity, impacts, strong
magnetic fields, static electricity and extreme temperatures). Do not insert any objects into the instrument.
2.3 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-2 PC when a measurement of any kind is in
progress. 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.
CAUTION: Use proper pressure medium. Use only clean, dry air or nitrogen gas. This instrument is not
designed for oxygen use.

WARNING: NOT EXPLOSION PROOF! Using this instrument in an area where devices with intrinsically safe
classification is recommended, is prohibited!
WARNING: Detachable main power supply cord with inadequate ratings should not be used.
WARNING: It is the responsibility of the operator to ensure that pressure in circuits connected to the
Traqc-2 PC 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-2 PC, 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 Traqc-2 PC, 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 instrument. If higher voltages
are connected, the interface control may be damaged.
This instrument is equipped with an overpressure protection, which protects the pressure sensor against
overpressure. As soon as the pressure on the pressure sensor increases to 1 bar above the measuring range
specified for the instrument, the supply to the pressure sensor will be cut off to protect the pressure sensor
from damage.

3. About the Traqc-2 PC
3.1 Functions of the Traqc-2 PC
The Traqc-2 PC is a portable pressure calibrator to perform a calibration, a simple pressure measurement or a leak
test. The Traqc-2 PC is not suitable for generating pressure. However, an UUT can be pressurized by means of a
supply pressure, which can be regulated with the pressure control valve if desired. This pressure will appear in the
display. The display can be set to psi, bar or kPa by briefly pressing the push button. The pressure indication on the
display can be zeroed by pressing the push button for a longer period of time.

Press and hold the zero/unit button for at least 3 seconds
•Connect the UUT to the test terminal (test 1 or test 2)
•Apply the pressure with the UUT
•Read off the pressure from the display
5.5 Charging the battery
The Traqc-2 PC is equipped with a Lithium-Ion battery, which must be charged regularly. When the instrument is
switched on, the status of the battery is visible on the display. The USB cable and the USB charging port are
provided. Always use the supplied cable or a similar cable with a maximum length of 0.8 meters.
The charging specifications are:
•Maximum 500mA
•5 VDC

6. Maintenance
6.1 Maintenance
Depending on the number of operating hours, the Traqc-2 PC should be maintained on a regular basis. We
recommend to contact our service department for tailor-made advice.
6.2 Calibration
The Traqc-2 PC is equipped with a pressure measuring cell, whose measurement accuracy decreases over time. This
is a natural process. To ensure that your Traqc-2 PC always displays the correct reading on the display, the Traqc-2
must be calibrated regularly at Tradinco Instruments. The recommended frequency of the recalibration (annually,
every two years or else) depends, among other things, on the number of operating hours and the required
measurement accuracy. Please contact our service department for tailor-made advice.
