and connecting cables during the following steps. Ensure that
the calibrator is in standby mode before making any
connection between the calibrator and Tester.
11. Apply 175V rms at 60 Hz. After allowing the reading to settle, press E on the
Tester.
12. Apply 350V rms at 60 Hz. After allowing the reading to settle, press E on the
Tester.
13. Apply 600V rms at 60 Hz. After allowing the reading to settle, press E on the
Tester.
14. Press E to start gain factor calibration.
15. Apply 175V rms at 60 Hz. After allowing the reading to settle, press E on the
Tester.
16. Apply 350V rms at 60 Hz. After allowing the reading to settle, press E on the
Tester.
17. Apply 600V rms at 60 Hz. After allowing the reading to settle, press E on the
Tester.
18. Press E to accept calibration factors and store in nonvolatile calibration memory.
The Tester will then return to normal operation.
The CALIBRATION ERROR message will disappear after calibration is
compete and power is cycled.
After calibrating the Tester, remove the battery access lid and batteries and return the
battery shunt spring to its normal position. Place a new calibration seal (P/N 937045)
over the calibration access port to prevent unintentional entry into the calibration mode.
When the calibration seal is in place, install batteries and reinstall the battery access lid.
