AC Power Output
Note
Tie the NORMAL LO and AUX LO
terminals together at the UUT or at the
Calibrator, via the “LO”s “tied” softkey. For
optimum phase performance, tie the LO
terminals at the UUT. At current levels
± 2.2 A, tie the terminals at the UUT using
heavy gage wire <10 m Ω resistance.
To set ac voltage at Calibrator NORMAL terminals
and ac current on AUX or 20A terminals:
1. Press R to clear the Calibrator output.
2. Connect to the UUT.
3. Set the UUT to measure ac power.
4. Enter the desired voltage output (up to 6
digits).
5. Press a multiplier key, if necessary.
6. Press V.
7. Enter the desired current output (up to 6 digits).
8. Press a multiplier key, if necessary.
9. Press A.
10. Enter the desired frequency output (up to 5
digits).
