If, after a calibration check, the results exceed the tolerance in the
specification (or other suitable performance standard), carry out a
calibration adjustment.

CALIBRATION ADJUSTMENTS
If the instrument is operating correctly, only zero and full-scale
calibration will vary. Any excessive non-linearity or temperature
effects indicate a fault. The instrument should be returned to a
qualified service agent.
