Performance Tests
XW Warning
To prevent possible electrical shock, fire, or personal injury, do not start the
performance test procedures unless the Product is fully assembled.
The performance tests verify the full operation of the Multimeter and measure the accuracy of each function against
product specifications. If the Multimeter fails a part of the test, calibration adjustment or repair is necessary. See
Calibration Adjustment on page 15.
