Performance Tests
2.Warm up the calibrator as required by its specifications.
3.Allow the temperature of the UUT to stabilize at room temperature (23 °C ± 5 °C [73 °F ± 9 °F] ).
4.Check the fuses and Battery, and replace them if necessary. Refer to “Testing the Fuses”, and “Replacing the Battery and Fuse”.
To verify the accuracy of the DMM functions, do the following:
1.Connect the Calibrator to the VΩ and COM input terminals on the Meter.
2.Turn the rotary switch to the function listed in each step of Table 3.
3.Apply the input level for each step listed in Table 3.
4.Compare the reading on the Meter display with the Display Reading in Table 3.
5.If the display reading falls outside of the range shown in Table 3, the Meter requires calibration adjustment or repair.
