6.3 Routine Measurement Calibration
The RS Series controller measures voltage and current by digitizing both voltage and current
waveforms on each available output phase. This data is subsequently processed and use to
calculate all measurement parameters such as VRMS, IRMS, Power, VA, Frequency etc. To
calibrate all measurements, only the voltage and current measurement functions need to be
calibrated. All other measurements are derived from these.
Connect the test equipment to the power source as shown in Figure 6-1. The DVM for
calibrating the measurement voltage should always be connected to the Remote Sense
connector on the Master cabinet.
Note: The Agilent 3458A Digital Multimeter or equivalent must be used for the following
calibration.
The shunt must be connected to the power source as shown in Figure 6-2. If the Current
Measurement can’t be successfully performed, adjust the Current Measurement Pot on the
System Interface board. This adjustment is described in the Non-routine Calibration section of
this manual. If the DC current measurement displays more than 70 counts on the display,
perform the non-routine current monitor adjustment.
