7.3 Routine Measurement Calibration
The BPS 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 7-1. The DVM for calibrating the
measurement voltage should always be connected to the Remote Sense connector on the Master cabinet.
