6. Connect red cable to input lead

and black cable to input lead
COM
then perform
the connection as indicated in Fig. 13 depending on the type of system under test. Put
the phase cable into the clamp jaws respecting the direction of current indicated by the
arrow (see Fig. 13). Connect the cable to the middle of the clamp jaws, in order to get
accurate measurements. Use the marks as a reference (see Fig. 2)
7. The value of AC powers (active , reactive and apparent) is
displayed. The instrument allows the evaluation of possible
DC components overlapped on a generic alternate waveform
signal (AC+DC) and this can be very useful for
measurements on impulsive signals typically of no-linear
loads (e.g.: welders, electric ovens, etc.)
