4.4.1
The process of phase calibration is as follow:
1. Setup input condition: Phase A, voltage input 220V, current input is the current
2. Load the dsPIC33F with the proper correction factors. This is automatically done
3.
4. Repeat for Phases B & C.
Note:
for region 1, voltage and current inputs of phase B and phase C are zero.
using the PC software. See Chapter 5. “PC Software”.
phase A.
Repeat steps 1 and 2 for phase lag calibrations for all current regions of
Phase Lag Calibration Process
If the power metering error still can not meet the requirement, the meter can
be calibrated a few more times. When doing so, simply input a new error
value into the front-end of the meter.
