How to use: 1. Connect the measured voltage to terminals 1 and 2 at the bottom left of the meter. 2. The integrated transformer is wired according to the wiring diagram in Figure 1, and the measuring loop wire is passed through the hole under the meter. The direction of wire insertion is chosen arbitrarily by the user depending on the operating situation. It can either enter through the circular hole at the top of the meter and exit through the bottom. The different insertion directions will not affect the measurement results. 3. Connect the external transformer according to the wiring diagram in Figure 2. Connect the two wires from the secondary end of the current transformer to the meter at terminals 3 and 4 at the top left of the meter, and pass the measuring circuit wires through the round hole in the device. 4. The device displays the measurement parameters after power-up. 5. When it is necessary to reset the energy measurement (during a measurement from zero), press and hold the (RESET) button on the right side of the control panel for 5 seconds until the energy display reads 0, then release the button. At this point, the electrical energy is measured from zero. The electrical energy function is to automatically record data when the power is off, i.e., when the measured voltage is disconnected or the power supply is turned off. The meter will automatically record the current test data, and when the measuring power supply is reconnected, the meter will continue to accumulate the previously recorded data. The diameter of the hole of the integrated transformer (CT) of 11mm can pass through the national standard copper wire of 12 square (mm)/can meet the load current of 100A, and the diameter of the hole of the external transformer (CT) of 15mm can meet the national standard 21-25 square (m) The standard copper wire passes through.
