Measuring single-phase voltage (220V) Check 300V <99.9A, the measurement of three-phase voltage (380V) Please tick 450V <99.9A. Remember!
For all distribution equipment table (such as power distribution cabinets / home distribution box / appliance repair, etc. Especially in the home [DZ47 / C45 / air switch] bus line by changing the meter, real-time monitoring of home appliances use state, Have avoided forgetting to turn off some household appliances when you go out to run, thus wasting electricity and resources!)
Now more home appliances, when you see the instrument display window current is large (or power is too large), you can selectively turn off the operation of an electrical appliance, so as to avoid the circuit temperature is too high, easy to aging wires and cause air switch Trip, over time will cause leakage within the fire and so on.
Main Specifications

11. By loading: rail (Universal Market) Note: shipped without rail
12. Built-in transformer: the measuring circuit leads through the hole on the right side of the meter (diameter of 11MM can pass through a maximum of 12 square mm (mm)) standard copper / can meet the maximum load current 100A) Note: The load through the instrument hole Passing from above or below does not affect current measurement accuracy.
13. External transformer (hole diameter 15.5mm) to meet the national standard 21-25 square (mm) standard copper through. (External Transformer (CT) need buyers message marked 10 from the order) Photographed baby 2-3 days delivery
14. The instrument is only suitable for pure AC 50-60HZ mains power supply, can not be used for square wave, inverter output and sine wave circuit to correct sine wave measurement, otherwise the meter will be permanently damaged!
Use and wiring method
1. Connect the measured voltage to terminals 1 and 2 on the bottom left of the meter
2. External transformer wiring diagram according to Figure Wiring, with the meter precision current transformer secondary end of the two leads were connected to the upper left 3 and 4 terminals, the measuring circuit leads through the transformer Round hole. (Transformer leads can be extended to the ideal location according to the appropriate equipment to install) to extend the length of 0.5-3 meters.
3. Built-in transformer wiring diagram according to the wiring diagram, the measuring circuit through the right circular hole of the instrument, the penetration of the wire according to the user's choice of use, you can from the bottom of the instrument into the round hole out above, Or from the instrument above the round hole into the following out into the direction of not the same will not affect the measurement results.
4. When the power is turned on, the meter displays the measured value. The power measurement shows the sequence of active power (W) displayed after power is turned on, and the apparent power (VA) is displayed by pressing the button on the left side of the instrument panel (SAM CK) Press the button again to display the power factor (cosΦ)
