Product Description

Multi-function Digital Meter can measure AC voltage, AC current, power factor, active power, electric energy and electric energy of cumulative time

Specification

• 1.Connect the measuring voltage to the 1 and 2 terminal.
• 2.Connections of meter with internal current transformer as graph 1. Make the wire through the hole in the meter and the direction chose arbitrarily.
• 3.Connections of meter with external current transformer as graph 2. Make the wire through the hole in the meter, and connect the two wires of the secondary transformer to the 3 and 4 terminal.
• 4.When power on, the meter will display the measure result of the AC voltage (V), AC current (A) and active power (W)and the correlative red led will light up.
• 5.When press the button of SAM CK (on the right of meter) down, the meter will change to display the measure result of power factor (cosΦ), electric energy of cumulative time (h) and electric energy (kwh) and the correlative red led will light up.
• 6.When press the button of SAM CK down again, the meter will display the measure result of the AC voltage, AC current and active power.
• 7. When power off, the meter can save the value of electric energy and electric energy of cumulative time, and go on cumulating data when the meter power-on next. When the meter is displaying electric energy, you can press down the button of SAM CK last for five seconds, then the electric energy and electric energy of cumulative time will to be zero and start to cumulate when release the button.
