Calibration of zero point
The function "Cali" enables the calibration of the sensor zero point. The current pressure is saved as
the new zero point. This is possible in the range +/- 3% of the instrument rated pressure. "neW" ap-
pears in the display when a calibration is carried out in the permitted range, otherwise "Err" is dis-
played.
This function is useful, for example, if there is always a residual pressure left in the system which
should be displayed as 0 bar.
CAUTION:
Following a zero point adjustment, for example on a 600 bar instrument, a pressure of up to 18 bar
will be displayed as 0 bar. Before any work is carried out on the hydraulic system, ensure that the
system is depressurised.
