Leak measurement function
Leak mode is used to determine
the pressure change over a defined
period, which can be adjusted. The
unit to be tested must be connected
to the high pressure calibrator on the
pressure side.
Start leak measurement
Activate the
MANO
menu. The display
shows
Leak dISP
. Press the ENTER
button and then the SELECT button.
Press ENTER to confirm
Leak Start
.
The leak measurement starts, and the
display alternates between the current
leak time and the pressure change
measured thus far.
Active leak measurement
During leak measurement, the lower
part of the display alternates each sec-
ond between the measurement time
that has now elapsed [mm:ss] and the
pressure change measured thus far.
End leak measurement early
To end a leak measurement early,
press the ENTER button and confirm
the ”
Leak Stop
” display by pressing
ENTER.
Leak measurement completed
If the leak measurement time has
elapsed or if the measurement was
manually ended ahead of time,
the display alternates between the
elapsed leak measurement time and
the measured pressure change.
Set leak measurement time
The leak measurement time is preset
to 10 minutes in the factory, and it can
only be changed with the ”Mano Con-
fig” software.

7. Maintenance / disposal
Venting the pressure system
Release the pressure completely and
then open the drain valve (10) and the
screwed sealing plug (7). Screw the
screw compressor (11) in completely.
Pump steadily with the manual boos-
ter pump (8) to clear the system of air.
When no more bubbles come out of
the recirculation pipe (6), close the
drain valve (10).
Changing the oil
We recommend that you have
KELLER change the oil. The entire
system is cleaned at the same time.
Only use type HLP 22 BP hydraulic oil.
Battery
The pressure calibrator is powered
by a 3 V button-cell battery (behind
the display). If the battery is low, the
battery symbol on the display
lights up.
Replacing the battery
Please switch the device off. Turn the
display section ring beyond the limit
stop until it is released from the hous-
ing section (turn through about 180°).
Open the battery compartment and
change the battery (type CR 2430).
