Special Information
 Do not connect voltages above 30V to the input
terminals.
 Do not attach test instrument to a high-pressure
source. Follow these instructions carefully to
avoid damage to tester and/or personal injuries.
 Do not use spanners on Quick fit adapters (finger
tight all the way down is all that is required).

NAG/IM/PPC-P/P+/01/22 18
 Events that may compromise the safe use of the
instrument and result in considerable personal or
material damage
 Do not connect Unit Tester Test with Potential
above 30V to the input terminals.
 Don’t press the arrow keys to change the units
while measuring mean peak value. If you need to
change the units go to UNIT option and then
select.
 Before switching off the calibrator, release the
applied pressure. Switch off the calibrator using
the On/Off key. Turning off the calibrator during
the calibration process will not damage either
the instrument or the pump.
 The instrument under test must always be
removed from the calibrator after use. There is
risk that the instrument may become damage
when we apply the pressure.
 Event that may compromise the safe use of the
instrument and result in slight personal or
material damage.

NAG/IM/PPC-P/P+/01/22 19
 Read this manual carefully before use in order to
avoid personal injuries and/or damage to the
equipment and to obtain maximum value of your
calibration system.
 If the pressure is below 1% of the range, and the
ZERO function cannot be activated, Please
contact us.

7. OPERATING INSTRUCTION
The Pressure source for the PPC-P -20 is built-in hand
held vacuum and Pressure pump with a Vernier
adjustment.
 Attach gauge or vacuum device to the Test port using
¼” BSP hose fitting connected to the Test port.
 Switch the indicator ON.
PRESSURE CALIBRATION
 Open the release valve in anticlockwise direction.
 Short input (p/v) terminal with the pressure terminal
using hose.
 Turn vernier valve in anti-clockwise direction and
maintain it in semi-open position.
 Set the indicator to zero by pressing <Zero> soft Key.
 Hand Tight release valve of the pump in clockwise
direction.
 Pump the movable handle until 80% of the pressure
is generated.
 Turn Vernier (fine adjustment) counter clockwise to
decrease pressure and clockwise to increase pressure
of item being tested. Turn Vernier slowly for precise
incremental pressure control.
 Upon completion of testing, open the Release valve
in anti- clockwise to release the Pressure to zero and
remove the test device from the hose end.
