ETCR EM4320 Large Caliber Three Phase Digital Phase Voltmeter, also known as three-clamp phase voltammeter, three-phase phase voltammeter tester, handheld phase tester, portable phase meter, vector diagram analyzer, is used to simultaneously measure three-phase AC voltage, current, inter-voltage phase, inter-current phase, voltage-current phase, frequency, phase sequence, active power, reactive power, apparent power, power factor, current vector sum, determine transformer wiring group, inductive, capacitive circuit, test the secondary circuit and the female difference protection system, and read out the phase between the groups of CTS for dynamic protection Relationship, check whether the wiring of the meter is correct or not, overhaul the line equipment, etc., to provide a safe, accurate and convenient new type of power meter for electricity inspectors.It is especially suitable for power billing systems and relay protection systems.

ETCR EM4320 Large Caliber Three Phase Digital Phase Voltmeter adopts a 2.8-inch TFT color LCD screen with dynamic display and vector diagram indication, which is clear at a glance.Its large-caliber current clamp is suitable for thick cables and high-current places.The intelligent design of the instrument reduces the cumbersome operation, reduces the possibility of misoperation, and has high test accuracy and easy to use.The instrument is equipped with anti-vibration, non-slip, high-insulation sheath, USB communication interface, can store 1200 sets of data, upload the stored data to the computer through the system software, realize online real-time monitoring and historical query, read, save, report, print historical data, etc.

1. Intelligent design reduces the cumbersome operation and reduces the possibility of misoperation. It has the advantages of high precision, high stability, low power consumption, and easy to use.
2. Input by voltage transformer and current clamp, there is no high voltage in the machine, and the three inputs are completely isolated, which is safe and reliable.
3. Large-caliber jaws are suitable for thick cables and places with high currents.
4. The test line adopts a special power cable, and the elastic rod plug and alligator clip are insulated and protected.
5. Storage function, 500 sets of data storage.
6. USB communication interface.
