It also permits to adjust an offset of the characteristic curve in
order to
•
compensate for the offset of the measuring system or
•
obtain a slightly positive zero for a 0 … 10 V AD converter.
The offset should not exceed 5% of the F.S. (+500 mV). At a
higher positive offset, the upper limit of the measurement range
is exceeded.
Zero adjustment using the ramp function can be
performed via
•
the <ZERO> button on the gauge,
•
the EtherCAT interface (

•
the diagnostic port (

Notice
Operate the gauge for at least 2 hours (until the signal is
stable).
Push the <ZERO> button with a pin (max. ø1.1 mm) and
keep it depressed. The <STATUS> LED starts blinking.
After 5 s, the zero adjustment value, starting at the current
output value, keeps continually changing (ramp) until the
button is released or until the setting limit (max. 25% F.S.)
is reached.
