Service Manual
Set Calibrator to
200 V, 50 Hz, OPR
400 V, 50 Hz, OPR
800 V, 50 Hz, OPR
6. Set the Calibrator to STBY.
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 / 200 V and then to OPR.
13. Fluke 434-II: check for a voltage readout V rms between 198.0 ... 202.0 V.
14. Check the 400 V range according to the table below.
4-14
