Calibration Adjustment
The ProcessMeter is calibrated using a closed-case procedure.
Calibrate the ProcessMeter once a year to ensure that it performs according to its
specifications.
Preparing for Calibration Adjustment
 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.
