Specification:Item Type: Watt‑Hour MeterModel: D52-2066Material: ABSMeasurement Accuracy: 1%±2 WordsMeasuring Range: AC Voltage: AC40.0-300.0V, AC Current: AC0-100.0ACurrent Display Resolution: 0.01APower Frequency: 45.0Hz-65.0HzPower Factor: 0.00-1.00PFMeasurement Speed: about 2 times per secondInstallation Method: Rail TypeHow 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.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.4. The meter displays the measurement parameters after the power is turned on.5. When it is necessary to reset the energy measurement (when measuring from 0), press and hold the button (RESET) on the right side of the instrument panel for 5 seconds (press and hold for 5 seconds) until the energy display is 0, release the button, At this time, the electrical energy is measured from 0.Package List:2 x Smart Watt-Hour Meter2 x Manual
