Technical Features

Used to measure total current, third harmonic, resistive current, resistive current peak, capacitive current, and active power of zinc oxide lightning arresters under power frequency voltage. It displays voltage and current waveforms and prints out test data.

1. This instrument features a 1024×600 dot 65K color resistive touch screen with a fully Chinese menu.

2. High-precision sampling and processing circuits and advanced Fourier harmonic analysis technology provide more reliable data.

3. It can measure harmonic content and measure single-phase or three-phase simultaneously.

4. It can output the fundamental peak value of resistive current.

5. The instrument has a large built-in memory. It can store a large amount of recorded information, including test data, waveforms, harmonics, etc. It can save up to 200 sets of measurement records in a cyclic update mode.

6. The instrument is equipped with a USB flash drive interface to store any set of test records (capacity is limited by the size of the USB flash drive).

7. The instrument's voltage test leads are equipped with fuses to prevent misconnection, and the instrument's voltage and current plugs are protected against misplugging.

8. The instrument is equipped with a wireless module for wireless voltage acquisition and wireless measurement with a host computer.

9. The instrument has a built-in high-precision real-time clock for date and time calibration.

10. The instrument has an external high-speed micro thermal printer for printing measurement data.

11. The instrument has a built-in high-capacity lithium battery and can operate continuously for 6 hours.

12. It can be connected to a mobile phone via Bluetooth for remote control.
