Measurement Setup for Phase Angle
Measuring Ranges
You can perform the calibration the phase angles for the following alternating-voltage measuring ranges:
•
AC 63.5 V
•
AC 110 V
•
AC 230 V
•
AC 400 V
Settings the Phase Angles Reference Voltage to Reference Current
•
Va to Ia = 0°
•
Vb to Ib = 0°
•
Vc to Ic = 0°
Calibration
To calibrate the phase angle, proceed as follows:
✧
Set up the measurement as shown in figure 10-11.
