Figure 1. Battery Replacement
The battery fits inside the battery door, which is then inserted into the case, bottom edge first, until it is fully seated.
Do not attempt to install the battery directly into the case. Once installed, tighten the battery door screw.
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).
