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 5.2.9 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 7-1. 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.
