Select Line Frequency
The calibrator is shipped from the factory for nominal operation at 60 Hz line frequency.
If you use 50 Hz line voltage, re-configure the Calibrator for optimal performance at
50 Hz. To do this:
1. From the front panel, go into SETUP, INSTMT SETUP, OTHER SETUP.
2. Push the softkey below MAINS to change the selection to 50 Hz.
3. Store the change.
After a correct instrument warmup (on for 30 minutes or longer), you must zero the
complete instrument again. See the section on “Zero the Calibrator” in Chapter 4.
