Data Hold Test
Use the following procedure to test the Data Hold function:
1. Press the Power button to turn on the UUT.
2. Press the Hold button and verify that the beeper sounds and the D•H symbol appears
on the display.
Accuracy Tests
Accuracy specifications are valid for one year after calibration when measured at an operating
temperature of 18 °C to 28 °C. Allow the UUT to stabilize at room temperature before you
perform the accuracy tests.
To verify the accuracy of the UUT functions, complete the following steps:
1. Connect the wire coils, listed in Table 2, across the current output terminals of the
calibrator.
2. Set the Calibrator Output for the value listed in Table 3.
3. Clamp the UUT around the wire coil at the output terminals.
4. Compare the UUT displayed reading with the Display Reading Limits in Table 3. If
any of the display readings fall outside of these limits, the UUT requires calibration
adjustment or repair.
