How to Use:
1. Connect the measured voltage to the 1 and 2 terminals on the bottom left of the meter.
2. The built‑in transformer is wired according to the wiring diagram in Figure 1, and the wire of the measurement loop is passed through the hole under the meter. The penetration direction of the wire is arbitrarily selected by the user according to the situation of use. Or penetrate from the circular hole on the top of the meter and come out from the bottom. The different penetration directions will not affect the measurement results.
3. Connect the external transformer according to the wiring diagram in Figure 2, connect the 2 wires of the secondary end of the accurate current transformer with the meter to the 3 and 4 terminals on the upper left of the meter, and pass the wires of the measurement circuit through the mutual inductance. The round hole of the device.
