Technical indicators:

1.Accuracy: 1％±2 words
2. Range: AC Voltage: AC 40.0-300.0V or AC 250.0-450.0V (You should select a meter type in your order) AC current: AC current 0-100.0A, the current resolution is 0.01A.
Frequency: 45.0Hz - 65.0Hz
Power Factor: 0.00-1.00PF
Electric power: 0-450000W, the resolution of the electric
power is 0.1W when the electric power is between .
is measured 0-9999.9W, otherwise the electric power resolution is 1W.
Electric energy: 0-99999kwh, the display of the resolution of the electric energy is 0.01kwh when measuring electrically Energy between 0-999.99kWh, the display of electric energy resolution is 0.1kWh when Measure the electric energy between 1000.0-9999.9kwh and the electric energy display Resolution is 1kwh when measuring electrical energy greater than 9999.9kwh
3. Speed: 2 times per second
4. Size: 54×80×64
5. Installation: DIN rail

Application procedure:

1. Connect the measuring voltage to terminals 1 and 2
2. Connections of meter with internal current transformer as a diagram 1. Pass the wire through the hole in the meter and the direction was chosen arbitrarily.
3. Connections of meter with external current transformer as diagram 2. Pass the wire through the hole in the meter, and connect the two wires from the secondary transformer to terminals 3 and 4.
4. When switched on, the meter displays the measurement parameters.
5. When the device is on, you can press and hold the button of SAM CK for 5 seconds, then the electric energy will be zero and start accumulating when you release the button. And when the power is off, the meter can store the value of electric energy and accumulate the data when the meter is turned on next time.

Attention:

The meter can only be used to measure 45-65 Hz AC city power.
