Performance Tests
2.Remove the Meter from its holster.
3.Remove two screws from the case bottom.
4.Separate the case bottom from the case top.
5.Remove the fuse from its holder and replace with an 11 A, 1000 V, FAST fuse having a minimum interrupt rating of 17,000 A. Use only Fluke PN 803293.
6.To
Cleaning the Meter
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings.
Performance Tests
XWWarning
To avoid electric shock, do not perform the performance test procedures unless the Meter is fully assembled.
The following performance tests verify the complete operation of the Meter and check the accuracy of each Meter function against its specifications. The recommended calibration interval is 12 months. If the Meter fails any part of the test, calibration adjustment and/or repair is indicated.
In the performance tests, the Meter is referred to as the unit under test (UUT).
Required Equipment
Table 2 lists the equipment required to conduct a performance test on the Meter.
