6. AC Source settings are shown as Table 10-5. Please follow the model to set W, PF &
I
p(max). According to the model to confirm if the values of Meter & Load meet to that in
Table 10-5.
Table 10-5
10.4.5 THD Measurement Verification
AC Source sets output voltage waveform to sine, AC Load enters CC mode and no loading.
Select ▼ at the upper side of rotary knob to press for twice, observe if THD measurement
value of Load and Meter panel meet to Table 10-6.
