product description Features: 1. Simultaneous display of measured AC voltage, AC current, power factor, active power, energy and energy. 2. Rail design easy to install. Product parameters: Accuracy: 1% ± 2 digits AC voltage: AC 200.0-450.0V AC current: 0.0-100.0A Active power: 0.0-30000w Electricity: 0.000-99999Kwh Accumulated time power: 0.00-999.59h Power Factor: 1.000-0.000 Test speed: 2 times per second Application method: 1. Connect the measured voltage to terminals 1 and 2. 2. Instrument and the internal current transformer connection shown in Figure 1 (please refer to the manual) Route the wire through the hole in the meter and select the direction you want. 3. Instrument and the external current transformer connection shown in Figure 2 (please refer to the manual) Route the wire through the hole in the meter and connect the two wires of the secondary transformer to terminals 3 and 4. 4. When the instrument is powered on, the AC voltage (V) measurement result, alternating current (A), active power (W) and related red light are displayed. note: The instrument can only be used to measure AC mains 50Hz, used to measure square wave, inverter output and correct sine wave will be destroyed. Package Included: 1x digital voltmeter ammeter
