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).
