As indicated earlier, for 3-Phase power system, repeat the preceding steps for the Phase B and
C outputs. The order in which the outputs for each phase are calibrated is not important.
Press the PHASE key to select each output to be calibrated. Monitor the output of the
respective phase by moving the HI input of the Digital Multimeter and the current shunt as
needed. The LO input should remain connected to the common LO of the sense connector.
The current measurement calibration for Phase A (ø1) should be done in both single and three
phase modes as separate calibration coefficients apply to each phase mode. Voltage
measurement calibration for phase A (ø1) can be done in either phase mode.
