6.3.1 Measurement Cal - AC
To calibrate AC measurements, set the power source to the AC mode. Select the
MEASUREMENT CAL entry from the MENU 3 screen. Refer to section 4.2.12 for relevant LCD
screen.
Note: For the following calibration steps put the external Digital Multimeter into AC
mode.
AC Volt Full-scale: Program the output to the 300 VAC range. Close the output
relay. Program the output to 240 VAC and 60 Hz. Go to the
MEASUREMENT CALIBRATION screen. Enter the actual AC
output voltage for the VOLT FS parameter and press the
ENTER key.
AC Current Full-scale: Apply a load to the output. Refer to Table 6-1. Program the
output to 120 VAC on the 150 VAC range and 60 Hz. (If a 150
VAC range is not available, select the 300 VAC range and
program the same 120 VAC output.)
Observe the actual output current and enter this value for the
CURR FS parameter. Press the ENTER key.
6.3.2 Measurement Cal - DC
To calibrate DC measurements, set the power source to the DC mode. Select the
MEASUREMENT CAL entry from the MENU 3 screen. Refer to section 4.2.12 for relevant LCD
screen.
Note: For the following calibration steps put the external Digital Multimeter into DC
mode.
DC Volt Full-scale: Program the output to +320 volts. Go to the MEASUREMENT
CALIBRATION screen. Enter the actual DC output voltage
displayed on the external multimeter for the VOLT FS
parameter and press the ENTER key.
DC Current Full-scale: Program the output to 0 volts on the 200 range. Apply load
resistor to the output. Refer to Table 6-1. Program 160 volts.
Enter the actual output current for the CURR FS parameter in
the MEASUREMENT CALIBRATION screen.
Repeat the preceding steps for the Phase B and C outputs. The order in which the outputs for
each phase are calibrated is not important.
Press the PHASE key to select each output to be calibrated. Monitor the output of the
respective phase by moving the HI input of the Digital Multimeter and the current shunt as
needed. The LO input should remain connected to the common LO of the sense connector.
