General

YD52-2066 DIN-rail multi-function Digital meter can measure AC voltage, AC current,    active power, power factor,frequence and electric energy and the same time. The meter have a colorful,full-view,high definition LCD todisplaythe measure parameters.

Technical data

Note：

The electric power resolution is 0.1W when measure electric power between 0-9999.9w, otherwise the electric power resolution is 1W.The display of electric energy resolution    is 0.01kwh when measure electric engery between 0-999.99kwh the display of electric    energy resolution is 0.1kwh when measure electric engery between 1000.0-9999.9kwh   and the display of electric energyresolution is 1kwh when measure electric engery larger    than 9999.9kwh.

Application Method

1. Connect the measure 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 meterand 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 display the measure parameters.

5. When power on, you can press the button of SAM CK last for 5 seconds, then the    electric energy will to be zeroand start to cumulate when release the button. And    when power off, the meter can save the value of electric energyand go on cumulating

data when the meter power-on next.

Attention:The meter can only use for measure 45-65Hz AC city electricity.
