4.3.4. POWER MEASUREMENT CALIBRATION

For calibration of power measurement perform the following steps:

1. Program 60 Hz and 135.0 volts and the maximum Current Limit value.

2. If any calibration screen is already displayed, the Power Calibration screen (CAL

PWR) may be displayed by depressing either the MON or PRG keys and then skip

to step 6. If a calibration screen is not displayed, depress the MNU key several

times until the screen shown below is displayed:

SNC = 01

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 resistance 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 in kilowatts. (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 power) B PRG ENT

10. Repeat step 6 for phase C.

11. Repeat step 7 except enter the key sequence:
