4.4.7 OUTPUT
PHASE ANGLE CALIBRATION
The phase calibration values for phases B and C are entered on the Phase Offset (POF) screen.
To calibrate the output phase angle, connect either a Phase Meter or an oscilloscope between the phase to be
calibrated and the phase A output. Program the phase B or C value to be calibrated from the Phase screen (PHZ). If
an oscilloscope is used the calibration is best performed with a programmed angle of 0 degrees.
To calibrate the output phase angle, program 120.0 volts and 60 Hz.
To access the POF screen perform the following key sequences:
1.
Access the Phase screen (PHZ).
2.
Depress the MNU key several times until the following screen is displayed:
SNC
=
01
CLK
=
02
WFV = 03
RNG = 04
3.
Enter the key sequence: 959 ENT
4.
Depress the MNU key several times until the Configuration menu screen is displayed:
CFG = 16
ALM = 17
FLM = 18
CLM = 19
5.
To display the POF screen enter the key sequence: 20 ENT
If an oscilloscope is used and the respective phase is programmed to 0 degrees and 200 Hz, a 3 degree error is
represented by 41 microseconds of the 0 volt point of the two signals.
The POF values may be either a positive or negative value. A negative value is entered by depressing the period key
(.) two times after the numerical value is entered before the PRG key is depressed.
