This initiates the zero point correction. The
ACT
(actual) value is indicated in the
display as 0.0 bar.
The correction remains active until the device is turned off.
The zero point correction sets the current ACT value to zero. In order
exclude erroneous measurements, ensure
no system pressure
is
being applied when carrying out this function.
OFL/ZEro
is displayed for 3 seconds if the measured pressure (0 bar) is
greater than 5% of the measurement range.
Zero point correction cannot be carried out.
Please ensure that
no system pressure
is being applied.
Turn off the device. Zero point correction is no longer
active when the device is turned off and on again.
