7.1.3 Option: “Freeze measured values”
As an alternative to the factory setting, the option “Freeze measured values” can be set
by Service during commissioning.
With this option, measured values are stopped and frozen during zero point adjustment
or reference point adjustment.
It takes some time after adjustment is completed until the measured values are acti‐
vated. The maintenance signal goes out and measuring operation can be continued
when the initial state is reached.
