Measurement Setup
Figure 10-10 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 10-10.
