Performance Tests
XWWarning
To prevent 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.
Performance tests should be performed bi-annually to ensure that the Meter is
within accuracy specifications. 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 device under test (DUT).
Required Equipment
Table 1 lists the equipment required to conduct a performance test on the Meter.
