Portable Double-Clamp Phase Voltmeter

SMG20000E Double Clamp Digital Phase Meter is specially designed for testing voltage, current, and phase onsite, it is in high-precision, low-price, portable hand-held, dual-channel input measuring products. It's easy to measure the phase between U-U, I-I, and U-I, identify the inductive circuit, capacitive circuit, and the phase sequence of three-phase voltage, detect the wiring group of the transformer, test the secondary circuit and bus differential protection system, read the phase relationship among the CT groups of a differential protection system, and check if the watthour meter was correctly wired. When testing customers do not need to cut off the measured circuit which is input by the split core current transformer. When measuring the phase between U1 and U2, the two input circuit loops are completely insulated isolation, so the possibility of misconnection is avoided, which may result in a short circuit or even burn the meter. The device with high-contrast LCD screen, and the character is big size, which helps to obtain the best visual effects.

Other technical features

1. The digital double-clamp phase volt-ampere meter has a delicate structure, easy to use, hand-held structure, in the current range of 10mA~10A, 3V~500V voltage range when measuring the phase without disconnecting the circuit and replacing the limit, the display adopts a high-contrast LCD screen, the word is up to 25mm, and the screen angle can be freely converted about 70 ° to obtain the best visual effect, the switch function and layout are reasonable, and the voltage, current and phase to be measured can be read by turning the switch;

2. Insulation resistance: The double-clamp phase volt-ampere meter adopts the latest patented current clamp, and the current resolution of this phase volt-ampere meter is 0.1mA; Voltage resolution is 0.1V;

3. Low power consumption: The SMG2000E digital double-clamp phase volt-ampere meter has volt-ampere meter micropower consumption design and has the function of battery voltage detection.

4. Withstand voltage: between the voltage input terminal and the case, between the clamp current transformer (current clamp) core and the clamp handle, and the secondary winding coil can withstand 1000V/50Hz, between the two voltage input terminals can withstand 500V/50Hz sine wave AC voltage for 1min test.

5. Insulation resistance: between the digital double-clamp phase volt-ampere line and the shell, between the two voltage input terminals: ≥10MΩ;
