12.5.10
P370 Zero Limit Deviation %
Sets the zero calibration deviation limit (±) from the last initial zero. If the accumulated deviation
of successive zero calibrations exceeds the limit, the zero calibration is aborted (f = 12.5).
Note
If the legal for trade certification switch has be
en set, the zero limit is ±2%.
Enter the maximum allowable % deviation, range is 1 to 12.5 %.
12.5.11
P371 Auto Zero Initiation Upper Limit
This parameter sets maximum load on the belt as a percentage of design load at which the
device will allow ’auto-zero’ to run, min. 1.0%, max. 10.0%, default 2.0%.
When the certification switch is set this parameter will assume the default value (2.0%).
Note
Material will not be totalized during auto zero calibrations
.
12.5.12
P377 Initial Zero
Resets the initial zero.
The initial zero is the reference zero to which all subsequent operator initiated zero calibrations
are compared in determining whether they have deviated beyond the zero limit (P370) (
f = 1).
Note
Refer to
Initial Zero (Page 74) on for execution.
12.5.13
P388 Initial Span
Resets the initial span for the span selected, multispan 1 to 8 (P388-01 to -08)
1)
.
The initial span is the reference to which all subsequent span calibrations are compared in
determining whether they have deviated beyond an accumulated ±12.5% of the initialspan (
f =
1).
Note
Refer to
Initial Span (Page 78) for execution.

BW500/L has one span entry possible, no indices will be presented.
