6.3.1 Measurement Cal - AC
AC Volt Full-scale: Turn OFF the ALC mode from the CONTROL menu first. Program the
output voltage to maximum voltage on the high voltage range and 400
Hz. Close the output relay. Go to the MEASUREMENT
CALIBRATION screen. Enter the actual AC output voltage for the
MVOLT FS parameter and press the ENTER key. Save this value by
pressing the ENTER key.
AC Current Full-scale: Calibrate the measurement current under a constant current condition
(OL MODE set to CC) or a voltage fault may be generated. Apply a
load to the output. Program the output to 80% of full-scale voltage
range on the low voltage range and 400 Hz. Observe the actual output
current and enter this value for the MCURR FS parameter. Press the
ENTER key. Save this value by pressing the ENTER key.
6.4 Output Calibration
The output calibration is performed automatically when the measurement calibration takes place. As
such, there is no need to perform this calibration again. The output calibration coefficients may be
viewed by selecting the OUTPUT CAL screen.
Output gain is set at the factory and the output calibration coefficients are pre-set. There is no need to
change the factory default settings unless any of the following conditions occurs:
1. Replacement of the CPU controller board. (CI P/N 6005-703-1)
If the output gains are found to be out of tolerance, they need to be adjusted. This requires removal of
the top cover and should only be done by qualified service personnel. In that case, refer to the non-
routine calibration section.
The factory output calibration coefficients are shown in the table below.
