is not displayed, depress the MNU key several times until the screen shown below is displayed:
SNC

*CLK
=
02
*WVF = 03
RNG = 04
3.
Enter the key sequence: 959 ENT
4.
Depress the MNU key several times until the configuration menu screen is displayed as shown below:
CFG = 16
ALM = 17
FLM = 18
CLM = 19
5.
Enter the key sequence 15 ENT to access the CAL PWR screen.
6.
Apply the LOAD RES value from Table 4-1 to the phase A output only. Measure the phase A output
current with the AC Digital Voltmeter and Current Transformer. Measure the phase A voltage from the
phase A sense to neutral sense. Multiply the voltage and current values to determine the power value.
(Note: The load must be resistive for the correct power value.)
7.
On the keypad enter the key sequence:
(Measured phase A power) A PRG ENT
8.
Repeat step 6 for phase B.
9.
Repeat step 7 except enter the key sequence:
(Measured phase B phase) B PRG ENT
10.
Repeat step 6 for phase C.
11.
Repeat step 7 except enter the key sequence:
(Measured phase C power) C PRG ENT
4.3.5 REMOTE
MEASUREMENT CALIBRATION
The measurement function of the AC Power System may be remotely calibrated. The equipment hookup is the same
as before except an IEEE-488 Controller must be used to program the AC Power System. The values for the VLT,
CUR and PWR strings must be derived from the external AC Digital Voltmeters and Current Transformer.
To calibrate the measured voltage, first program the AC Power System to 135.0 volts and 60 Hz. Send the following
calibration string:
CAL VLT (1)
(Desired voltage value for phase (1))
To calibrate the measured current send the following string:
CAL CUR (1) (Desired current value for phase (1))
