Product features:

Fully automatic instrument, one wiring can measure three-phase data at the same time, or single-phase data separately.

It has the function of HARMONIC ANALYSIS and can accurately analyze the content of fundamental wave and 3rd, 5th and 7th harmonics.

Anti-interference function to ensure accurate and reliable data.

Voltage phase selection function. The voltage signal can be connected to any phase A, B and C.

Angle compensation function (when the voltage signal is 220V).

8.0-inch color touch LCD screen can display three-phase data and waveform at the same time.

AC / DC dual-purpose, built-in high-capacity lithium-ion battery, one charge can work continuously for about 6 hours.

There are three measurement methods: wired, wireless and no Pt, which support the signal acquisition of 220V maintenance power supply.

RS232 serial communication; USB interface

Wireless data transmission eliminates the tedious work of long-distance wiring of voltage measurement lines and reduces labor intensity;
