ETCR4700 Three Phase Digital Phase Volt-Ampere Meter is a well-developed full-automatic, multi-functional, digital, intelligent meter specifically designed for field testing,featuring high accuracy, high stability, low power consumption, easiness to use and so on. It can directly measure AC voltage and AC current without opening the measured circuit, phases between three voltages, three currents and phase between the voltage and current; in addition, the power factor and power of the circuit can be indirectly measured, it can also be used to distinguish three-phase sequence, transformer wiring group, inductive and capacitive circuits, test second circuit and bus differential protection systems, read the phase relationship between CTs of the differential protection, check the meter wiring right, repair lines and equipment, etc. 

 

ETCR4700 Three Phase Digital Phase Volt-Ampere Meter has well designed shell mould made of newest material, attach with shakeproof, skidproof, high insulation sheath, has a 240dots×160dots LCD screen, all the test data display on the screen simultaneously, vector diagram indication, and looks exquisite and comfortable.  The instrument is equipped with USB interface, can store 500 sets of data, upload the stored data to the computer through the system software, real-time online real-time monitoring and historical query, dynamic display, can read, save, report, print historical data.
