Calibration of sensor zero point (Calibrate) YES/NO ON
"YES": The base pressure is saved as
the new zero point. This is
possible in the range +/- 3% of
the unit’s nominal pressure.
"NEW" appears in the display
when a calibration is carried out in
the permissible range, otherwise
"Err" is displayed.
This function is useful for example if there
is always a residual pressure in the system
which should be displayed as 0 bar.
Please note:
Following a zero point calibration, for
example, on a 600 bar unit, a pressure
of up to 18 bar is displayed as 0 bar.
Before any work is carried out on the
hydraulic system, ensure that the system
is de-pressurised.
