Features

Full viewing angle colorful LCD screen, 178° wide viewing angle. 

Integrated transformer, precise measurement. Connect the measured voltage to terminals 1 and 2 at the bottom left of the meter.

2. The built-in 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 penetration is arbitrarily chosen by the user depending on the usage situation. Or enter through the circular hole at the top of the meter and exit at the bottom. 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 from the secondary end of the precise current transformer with the meter to terminals 3 and 4 on the top left of the meter, and pass the wires of the measuring circuit through the mutual inductance.The round hole of the device.

4. The device displays the measurement parameters after powering on.

5. When it is necessary to reset the energy measurement (when measuring from zero), press and hold the (RESET) button on the right side of the dashboard for 5 seconds (press and hold for 5 seconds) until the energy display is 0, release the button, At this time, the electric energy is measured from zero.Electric power has the function of automatically saving data when the power supply is turned off, that is, 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 built-in transformer (CT) hole diameter of 11mm can pass through the national standard 12 square copper wire (mm) / can meet the charging current of 100A, and the external transformer hole diameter (CT) of 15mm can meet the national standard 21‑25 square (m) Standard copper wire passes through.
