Selecting Calibration Parameters
Following the controlled power-up, your APS unit enters the Low Voltage
(
) calibration mode. The calibration sequence will always begin at phase
R. Upon completion of Phase R calibration, pressing FREQUENCY ﹀ will begin
the calibration sequence for phase S; then, again for phase T.
Phase R is equivalent to North American Phase A
Phase S is equivalent to North American Phase B
Phase T is equivalent to North American Phase C
Press the FREQUENCY ﹀ or ︿ buttons to select the system parameter you are
going to calibrate.
Pressing FREQUENCY ﹀ proceeds to the next calibration mode. Pressing
FREQUENCY ︿ returns to the previous step.
Low-voltage mode (
) calibration
High-voltage mode (
) calibration
Low-current mode (
) calibration
High-current mode (
) calibration
Low-power mode (
) calibration
High-power mode (
) calibration
Calibration Frequency
Please note, the calibration frequency is internally selected to be 60 Hz. Consequently,
there is no user-selectable calibration frequency setting. Please use resistive loads for
all of your load-calibration procedures. Resistive loads are not sensitive to frequency.
