the calibrator is in standby mode (STBY).
To prepare for the performance test:
1. Make sure that you have the required equipment (refer to Table 2).
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 “Fuse Test”, and “Fuse
Replacement”.
To verify the accuracy of the Meter functions, do the following:
1. Connect the Calibrator to the VΩ and COM input terminals on the Meter.
