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 5.3
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.
BEFORE STARTING 5.4
Use only original parts supplied by the manufacturer. To do an
accurate calibration, use the following:
• Calibration equipment specified in Table 5-1.
• Stable temperature environment: 21 ±1°C (70 ±2°F).
Before starting a calibration procedure, it is recommended leaving
the equipment in the calibration environment for a minimum of two
hours.
