Design Changes; Recalibration - Siemens Milltronics BW100 Instruction Manual

If the span adjust value is within the accuracy requirements of the weighing system, the
material test was successful and normal operation can be resumed.
If the span adjust value is not acceptable, repeat the material test to verify repeatability. If
the result of the second material test differs considerably, consult Milltronics or its agent.
If the span adjust values are significant and repeatable, perform a manual span adjust:
Maneuvering
refer to
page 18 for
parameter selection
and value change
if % span adjust is
negative, be sure
to enter as
negative value
Verify the results of the span adjust by material test or return to normal operation

Design Changes

Where parameters have been changed with a resultant impact on the calibration or do
not take effect until a recalibration is done, the parameter warning icon is displayed. In
order to clear the icon, perform a zero and span recalibration after the reprogramming
session is complete.
If significant changes have been made, an initial zero (P377) and/or initial span (P388)
may be required.

Recalibration

In order to maintain the accuracy of the weighing system, periodic zero and span
recalibrations are required. Recalibration requirements are highly dependent upon the
severity of the application. Perform frequent checks initially, then as time and experience
dictate, the frequency of these checks may be reduced. Record deviations for reference.
