WARNING!
Before installation, commissioning and operation, ensure that the appropriate
portable low-pressure controller has been selected in terms of measuring range,
design and specific measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
Further important safety instructions can be found in the individual chapters
of these operating instructions.
2.1 Intended use
The Traqc-20 LPC is used for testing and calibrating pressure sensors.
This instrument is not permitted to be used in hazardous areas!
The instrument has been designed and built solely for the intended use described here, and may
only be used accordingly.
The technical specifications contained in these operating instructions must be observed. Improper
handling or operation of the instrument outside of its technical specifications requires the instrument
to be taken out of service immediately and inspected by an authorized service engineer.
Handle electronic precision measuring instruments with the required care (protect from humidity,
impacts, strong magnetic fields, static electricity and extreme temperatures, do not insert any
objects into the instrument or its openings). Plugs and sockets must be protected from
contamination.
If the instrument is transported from a cold into a warm environment, the formation of condensation
may result in instrument malfunction. Before putting it back into operation, wait for the instrument
temperature and the room temperature to equalize.
The manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.

4.1 Electrical connections on the rear
1) USB interface
2) RS-232 interface
3) Connection for power supply unit
4.2 Voltage supply
The low-pressure controller is factory set for connection to a voltage supply of DC 24 V.
The power supply connector is located on the rear panel.
DANGER!
Operation using a defective power supply unit (e.g. short circuit from the mains
voltage to the output voltage) can result in life-threatening voltages at the instrument!
Only the original power supply unit included in initial delivery (Mascot model 9926)
should be used.
· Design the wiring particularly carefully when connecting to other devices. Under certain
circumstances, internal connections in third-party devices (e.g. GND connected to the ground)
can lead to impermissible voltages that could compromise or even destroy the function of the
device itself or a device connected to it.
· The mains plug must always be plugged in to a mains socket and be accessible, so that one can
always remove it from the mains socket without difficulty.

4.4 Pressure connections
· Differential pressure instruments are connected to the + and the - connections of the instrument.
· Relative pressure instruments are connected to the + connection (- connection is open to
atmosphere).
· Instruments for negative gauge pressure are connected to the - connection (+ connection is open
to atmosphere).
Only connect test and calibration installations once the system has been
depressurized!
Never perform functional tests with compressed or medical air. This can damage
instruments with low pressure ranges.

modes
5.1 Operating mode 'Control' (CTRL)
The CTRL mode is used for the calibration of pressure sensors and other pressure instruments. In
CTRL mode, the pump is active and regulates according to the desired pressure. The internal
sensor provides the current value on the display.
Setting
1. Press the MENU button. Confirm the menu point MODE with OK and press the UP / DOWN
button until CTRL appears. Confirm with OK
2. In the submenu RANGE the upper limits of the pressure range are defined (UP / DOWN and
LEFT / RIGHT buttons) and confirmed with OK
3. In the submenu UNIT the pressure units are defined (UP / DOWN buttons) and confirmed with
OK
4. In the submenu STEP the step sequence in % is defined (UP / DOWN buttons and LEFT /
RIGHT buttons), confirmed with OK
5. With the MENU button, you can exit the submenu
Use
The unit is located at exit from the menu in VENT mode, ie the sensor of the calibrator is vented. On
the middle of the top, the target pressure is displayed. On the bottom of the display, the per cent
value is shown. When leaving the menu, this value is 0%. Switch between target pressure and per
cent value with the OK button.
· The percentage value can be changed with the UP / DOWN (in the fixed step sizes) and using the
0% / 100%.
· The target pressure can only be changed with the UP / DOWN. With 0% / 100% to the
appropriate place, the target pressure be jumped.
Example
Target pressure: By pressing the OK button, you can switch between the percentage and target
pressure. value. Press the OK button until the value (top center display) outlined in bold. Press the
0% or 100% button to jump to the selected location. Choose the required value with the UP and
DOWN button. Push the OK button to exit target pressure. The marker moves to the percentage
value. (middle of the display)
When the calibratos displays a stable value, the data can be recorded:
· Nominal value: Right below
· Unit: Right above
· Actual value: On the display of the connected device
· Reference value: Middle of the display
