Description
Multi-function Digital meter can measure AC voltage, AC current, active power, power factor, frequency and electric energy and the same time. The meter have a colorful, full-view, high definition LCD to display the measure parameters.
Application Method:
- Connect the measure voltage to the 1 and 2 terminal.
- Connections of meter with internal current transformer as graph 1. Make the wire through the hole in the meter and the direction chose arbitrarily.
- 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.
- When power on, the meter display the measure parameters.
- When power on, you can press the button of SAM CK last for 5 seconds, then the electric energy will to be zero and start to cumulate when release the button. And when power off, the meter can save the value of electric energy and go on cumulating data when the meter power-on next.
Attention: The meter can only use for measure 45-65Hz AC city electricity.
