Double Clamp Digital Phase Meter is special designed for testing voltage, current and phase on site, it is in high-precision, low price, portable hand-held, dual-channel input measuring product. 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 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 watt hour meter was correctly wired.
1. Ingenious structure, easy to operate, hand held structure
2. no need to disconnect circuit or change measurement range under 10mA-10A, 3V-500v when test phase
3. use high contrast LCD, characters can be 25mm, the screen angle can be 70°to obtain the best visual effects
4. the function and layout of the switch are reasonable, rotate the switch can read the measuring U, I and phase.
5. High resolution, with new type patent current clamp, current resolution up to 0.1mA; voltage resolution up to 0.1V.
6. Low power consumption, with the function of testing the voltage of battery
