Instruction Manual

safety must be followed whenever
work is carried out. Internal regula-
tions issued by the operator must
be followed, even if they are not
mentioned in these instructions.
Never use the high pressure calibra-
tor together with an external pressure
source.
Do not remove any connected compo-
nents (e.g. test objects) when the high
pressure calibrator is under pressure.
Open the screwed sealing plug before
removing parts.
Do not use Teon tape to seal the
pressure connection.
Residues of
Teontapecouldpenetratethehigh-
pressure calibrator and damage it.
Only use the adapters and seals that
are available as accessories.
Do not store the calibrator under pres-
sure: only store the high pressure cali-
brator with the drain valve open.
Avoid the action of force of any kind
on the high pressure calibrator and its
operating controls.
Do not use high pressure calibrators if
they are damaged or faulty.
3. Operating the HPX calibrator
Operating the high pressure calibrator
is described starting on page 16.
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 pressure in
the system!
If you can no longer reach the desired
pressure, please consult the section on
"Maintenance" tond 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
display, it will show
OFL(overow)or
UFL(underow).
If pressure outside the device’s
measuring range is applied, the
last valid pressure value that was
measured will ash on the display
(overload warning).

4. Description of the functions
Menu navigation
If the selected function or unit is not ac-
tivated by pressing the ENTER button
within 5 seconds, the display will return
to measuring mode without changing a
setting.
Function Reset Description
Min. / max. display Shows the peak and trough pressure values
measured thus far.
(Display is shown with reduced resolution)
Leak measurement Leak mode is used to determine the pressure
change over a dened period, which can be
changed.
(Leak measurement period, factory setting:
10 minutes)
Zero the display
Permanently sets the applied pressure as the new
pressure zero point.
Reset
display
Resets the pressure zero point to the factory set-
ting.
Automatic
switch-off function
(Cont = Continuous) The device switches off
automatically after a dened period (which can
be changed), starting from the last time a button
was pressed. (Switch-off period, factory setting:
15 minutes)
