3. Operating the calibrator
Operating the high pressure calibrator
is described starting on page 6.
Connect the test object
You can connect your test object to the
high pressure calibrator via the pres-
sure connection (9).
Pressure generation
When using the calibrator, the screwed
sealing plug (7) must be opened (2
turns), so that overpressure cannot
build up in the oil reservoir.
Use the manual booster pump (8) to
set the pressure to about 10 bar. You
can use the screw compressor (11) to
increase or reduce the pressure.
Release pressure
1. Open the screw compressor (11)
completely
2. Open the drain valve (10)
IMPORTANT!
Do not open if there is high pres-
sure in the system!
If you can no longer reach the desired
pressure, please consult the section on
"Maintenance" to find out how to vent
the system.
Zeroing the device
Open the drain valve (10) to release
any pressure that may have built up.
If the pressure display does not show
zero, perform a zeroing procedure
(
Set Zero
) and then close the drain
valve.
Information about the display
If no pressure can be shown on the dis-
play, it will show
OFL
(overflow) or
UFL
(underflow).
If
pressure
outside
the
device’s
measuring range is applied, the
last valid pressure value that was
measured will flash on the display
(overload warning).
