Using the Traqc-2 PCHP
5.1
Applying supply pressure to the UUT
•
Turn on the instrument
•
Press short the zero/unit button to set the desired unit (barg, psig or kPag)
•
Connect the UUT to the test terminals (test 1 or test 2)
Using a polyflo connector
•
Turn the selector switch in the forward direction
•
Open and close the pressure relief valve
To release the current pressure
•
Zero the pressure reading with the zero/unit button
Press and hold the zero/unit button for 3 seconds
•
Generate pressure with the built-in hand pump
•
Pressure is generated to the UUT and internal reference sensor
Fine-tune the pressure with the built-in volume controller
5.2
Performing a comparative measurement
•
Operate the instrument as described in section 5.1
•
Turn the selector switch in the blocking direction
•
Wait for the pressure to stabilize
Depending on the environmental conditions, this may take some time
•
Read the difference in pressure between the Traqc-2 PCHP and the UUT
5.3
Performing a leak test
•
Operate the instrument as described in section 5.1
•
Turn the selector switch in the blocking direction
The internal circuit of the Traqc-2 that is part of the leak test is as short as possible
•
Wait for the pressure to stabilize
Depending on the environmental conditions, this may take some time
•
Zero the pressure reading with the zero/unit button
Press and hold the zero/unit button for at least 3 seconds
•
Read off the pressure history from the display
5.4
Measuring external pressure
If no pressure has to be generated, the pressure of an UUT can be measured with the Traqc-2 PCHP. The pressure
can be read off directly from the display. The test circuit and the Traqc-2 PCHP is as short as possible:
•
Zero the pressure reading with the zero/unit button
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 PCHP 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
