Calibration Adjustment
The following sections comprise the Calibration Adjustment Procedure. The procedure is
meant to bring the UUT back into specification following repair of the UUT or when the
UUT fails the Performance Test. The required equipment is listed earlier in Table 2.
Calibrate the ProcessMeter once a year to ensure that it performs according to its
specifications.
Preparation
 Warning
To prevent possible electric shock, fire, or personal injury:
• Do not use the ProcessMeter if it looks damaged.
• Inspect the ProcessMeter for damage, especially around the input
terminals. Inspect the test leads and test connections for
damaged insulation or exposed metal.
• Look for cracks, missing plastic or damaged insulation. If damage
is detected, do not continue; contact Fluke to have the
ProcessMeter serviced.
• Make sure that the battery compartment door on the ProcessMeter
is closed and latched before using it.
• Check the test leads for continuity. Replace damaged test leads as
necessary.
• Do not use the ProcessMeter if it appears to operate abnormally.
Protection designed into the ProcessMeter might be impaired. If in
doubt, have the ProcessMeter serviced.
• To avoid electrical shock, always place the calibrator in the
Standby (STBY) mode between tests and before handling the test
connections or test cables.
• Some of the calibration adjustment procedures involve the use of
high voltages and should be performed by qualified personnel
only.
