The digital display multi-function meter is used to display the measured AC voltage, AC current, power factor, active power, electric energy (electric degree) and the timing of electric energy at the same time on the instrument.
Buy Please note: Measure the voltage of 220V Check the 80-300V, measure the voltage of 380V Check the 200-450V, 200-450V If used for 220V voltage, when the voltage is lower than 200V or at 200V, the instrument does not work, or there will be a flash Screen. Please note! ! !
Household check: 80-300V ~ 100A
Note: If you want to measure ABC / three-phase voltage and current at the same time, you must buy 3 instruments, 3-phase 4-wire check 80-300V / 3-phase 3-wire check 200-450V

Use and wiring method
1. Connect the measured voltage to terminals 1 and 2 on the bottom left of the meter.
2. Built-in transformer wiring diagram according to a wiring, the measuring circuit leads through the instrument below the hole, the direction of the wire into the user according to the use of arbitrary choice, you can from the instrument below the hole into it , 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.
3. External transformer wiring diagram according to the wiring diagram two, with precision current transformer secondary end of the two wires were connected to the upper left of the meter 3 and 4 terminals, the measurement circuit through the mutual inductance wire The round hole of the device.
4. When the power is turned on, the measurement display functions displayed by the meter are voltage (V), current (A) and active power (W) respectively. The red LED on the right of the corresponding display window lights to indicate the corresponding display function.
5. Click the button on the right side of the instrument panel (SAM CK) and the three displayed functions are converted into power factor (cosΦ), time accumulation (h) and power (kwh) respectively. The corresponding green LED on the right of the display window Light, indicating the corresponding display.
6. Press the button again (SAM CK), the display of the meter is converted back to voltage (V), current (A), active power (W).
7. When the need for energy measurement and reset the timer (measured from zero), the measurement function is converted to the power measurement function is the right indicator light green indicator light, then hold down the button (SAM CK) 5 seconds The clock (press and hold for 5 seconds) until both the power and timer displays are 0, release the button, then the power and time display of both displays are measured from scratch. Power and Timing Both displays have the function of automatically saving data when the power is off. That is, when the measuring voltage is disconnected or the power is cut off, the meter will automatically save the data of the current test. When the power is reconnected, the meter will store the data in the original Continue to accumulate.
Note: This instrument is only suitable for mains supply with pure AC 50-60HZ. It can not be used for square wave, sine wave circuit of inverter inverter output and correction wave, or the meter will be permanently damaged!
