4.4 Zeroing the Gauge
The gauge is factory calibrated while "standing upright"
(
→ "Calibration Test Report").
We recommend performing a zero adjustment, when the
gauge is operated for the first time.
Due to long time operation or contamination, a zero drift could
occur and zero adjustment may become necessary.
For adjusting the zero, operate the gauge under the same con-
stant ambient conditions and in the same mounting orientation
as normally.
4.4.1 < ZERO > Adjustment
The zero can be adjusted via
• the <ZERO> button on the gauge,
•
the diagnostic port (
→
 [3]),
•
briefly apply the supply voltage to the digital input
"Remote Zero" (pin 10),
•
the RS232 interface (
→
 [2], [3]),
• the Ethernet interface ( →

[1]),
• the wireless network ( →  [4], [5]).
While the gauge is being heated and/or under atmos-
pheric pressure, the zeroing function is locked in order
for operating errors to be prevented.
