6.4 Routine Output Calibration
For best results, it is recommended to perform the measurement calibration procedure first. See
section 6.3.
Follow the steps outlined in this section to perform a routine output calibration. Table 6-3 shows
the individual calibration points in a summary format. The following text is a more detailed
explanation of the procedure.
Setup:
Connect the test equipment to the power source depending on model configurations as shown in
Figure 6-1. Note that no load is required for output calibration.
6.4.1 Output Cal
300 VAC Range DC Zero:
Program the output to the 300 VAC Range by pressing and
selecting the 300 Range with the shuttle. Go to the OUTPUT
CAL screen, select the VOLT ZERO parameter and adjust the
output to 0.0 ± 0.005 VDC.
Save this value by pressing the
SET key.
300 VAC Range Volt Full-scale: Program the output to 240.0 volts and 60 Hz. Once the output
settings are made, turn on the ALC mode and allow the output
on all phases to settle. Next, proceed to the output calibration
screen. Select the VOLT FS parameter and enter the set
voltage in the full-scale calibration window followed by the
ENTER key.
Save this value by pressing the SET key
.
400 VDC Range Volt Zero:
Press the PROGRAM key. Press the PROGRAM key and
select the 400 VDC Range. Program 0.0 VDC. Go to the
OUTPUT CAL screen and adjust the VOLT ZERO for 0.0 ±
0.005 volts DC on the output.
Save this value by pressing the
SET key.
6.4.2 Output Calibration Summary
The following Table is a summary of the preceding calibration steps. Note that Series II MX
models have fewer calibration coefficients.
Program the following values in the table and make the adjustments in the OUTPUT
CALIBRATION screen. Select the phase to be calibrated by pressing the PHASE key.
