Initial Zero - Siemens Milltronics BW500 Operating Lnstructions

The cause of the increased deviation must be found and rectified. A zero recalibration as
previously described can then be retried.
If the operator deems this deviation to be acceptable, set P377 to 1 to invoke an initial
zero calibration. Further deviation limits are now based on this new initial zero.

Initial Zero

Perform an initial zero if necessary when calibration is out of range message is shown.
