High-Voltage Mode (U-HI) Calibration
1. At the FREQUENCY Display, press the ﹀ buttons to select
(V-HI). The
high-voltage parameter is calibrated after you calibrate the low voltage.
2. At the OUTPUT Terminals, with no load attached, carefully connect a certified,
calibrated RMS voltmeter, of at least 0.2% accuracy, to the output of Phase R (North
American Phase A). After calibrating Phase R, you will repeat this step for Phases
S and T (North American Phases B and C).
3. At the MULTIMETER Display, press the TEST button. The APS unit will
automatically perform a high-voltage output reading and will output approximately
300 VAC. The external RMS voltmeter will display the actual voltage output. The
CURRENT Display shows the calibration value (See Calibration Table, below).
4. At the CURRENT Display. adjust the voltage using the CURRENT ︿ or ﹀
buttons until the metered values match.
5. At the MULTIMETER Display, press the LOCK button to finish high-voltage
calibration.
6. Proceed to the next calibration function, unless this completes system calibration.
7. Note, to exit the Calibration Mode, your APS system must be restarted after you
have completed ALL calibration operations.
