Service Manual
1. Set the Analyzer to 120 V, 60 Hz nominal (SETUP menu, arrow and ENTER keys).
2. To check the A/L1, B/L2, C/L3 inputs: connect the N input to Ground (See Figure 4-
3. Set the Calibrator to 60 Hz, 60 V and then to OPR.
4. Fluke 434-II: check for a voltage readout V rms between 59.4 ... 60.6 V.
5. Check the 120 V range according to the table below.
Set Calibrator to
60 V, 60 Hz, OPR
120 V, 60 Hz, OPR
