Service Manual
Set Calibrator to
115 V, 50 Hz, OPR
230 V, 50 Hz, OPR
460 V, 50 Hz, OPR
6.
Optional Test. Bandwidth Check of Channel A/L1, B/L2, C/L3 (*):
7. Set the Calibrator to 215 V, 50 Hz and OPR
8. Now check the voltage channels one by one. Use the Calibrator's field edit function
9. Increase the frequency to 3 kHz.
Voltage Channel to be verified
A/L1
B/L2
C/L3
10. Set the Calibrator to STBY.
Accuracy Check of Channel N (Neutral):
11. Connect the N input with the C/L3 input (See Figure 4-4). A/L1, B/L2, C/L3 now
12. Set the Calibrator to 50 Hz / 115 V and then to OPR.
13. Fluke 434-II: check for a voltage readout V rms between 113.8 ... 116.2 V.
14. Check the 230 V range according to the table below.
4-12
