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.
