4.3.3 CURRENT
MEASUREMENT CALIBRATION
For calibration of current measurement perform the following steps:
1.
Program 60 Hz, 135.0 volts and the maximum Current Limit value.
2.
If any calibration screen is already displayed, the Current Calibration screen (CAL CUR) may be
displayed by repeatedly depressing either the MON or PRG keys and then skip to step 6. If a
calibration screen is not displayed, press the MNU key several times until the screen shown below is
displayed:
SNC = 01
*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: 14 ENT to access the CAL CUR screen.
Determine the full load resistive value from the LOAD RES value from Table 4-1.
6.
Apply the load to the phase A output only. Measure the phase A output current with the AC Digital
Voltmeter and Current Transformer.
7.
On the keypad enter the key sequence:
(Measured phase A current. Example 11.05) A PRG ENT
After about 5 seconds the current measurement function for phase A will be calibrated.
8.
Repeat step 6 for phase B.
9.
Repeat step 7 except enter the key sequence:
(Measured phase B current) B PRG ENT
10.
Repeat step 6 for phase C.
11.
Repeat step 7 except enter the key sequence:
(Measured phase C current)
C PRG ENT
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
