Danger! High voltage! Please pay attention to safety!
6.1.1 Connection: Clamping on three phase wires respectively with the three clamps (Shown in
Fig-1).
6.1.2 The detected wire at the clamp with mark " " (Shown in Fig-2).
6.1.3 Press the red color "ON" startup key, the power indicator lamp will light up. If the power
lamp does not light up, this will indicate either a low battery or a damaged instrument, in
which case you will need to replace the battery or send it for repair.
6.1.4 After starting up, if the four phase sequence indicators light up clockwise, and the instrument
makes intermittent short chirps, then the clamped phase line is positive phase sequence L1-
L2-L3 (U-V-W) (Figure 1). If the four phase sequence indicators light up counterclockwise,
and the instrument makes a continuous sound, then the clamped phase line is in the reverse
phase sequence L3-L2-L1. (W-V-U) (Figure 2).
