Zero Calibration. Current Zero.
Clear belt. Press ENTER to start
For example: the current zero count.
Press the following key:
Zero Calibration in progress
Current Reading:
For example: the load reported while calibration is in progress
Calibration complete. Deviation
Press ENTER to accept value
For example: the calculated deviation in % of full span and the new zero count, if accepted.
A deviation that is high (Siemens recommends 3 or higher) should be investigated further to
identify the source).
Calibration is out of range
Deviation report:
If unacceptable, press the following key to restart:
This indicates that the mechanical system is errant. P377, initial zero, should be used judiciously
and only after a thorough mechanical investigation.
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.
Press the following key:
Zero Calibration. Current Zero
Clear belt. Press ENTER to start
For example: zero calibration is accepted, played as the current zero.
