OPERATING INSTRUCTIONS
NOTE: Select the correct CLAMP in the SETUP menu. When the current probe is connected to the
power analyzer, the power analyzer will automatically detect the range selected.
NOTE: Select the correct frequency (Hz) in the SETUP menu.
WARNING: All the current probes connected to the power analyzer must be of the same model and
same range. Mixed models and different ranges will yield incorrect measurement results.
