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. The instrument displays voltage and current waveforms and prints out test data.

1. 1024×600 dot 65K color resistive touch screen with full Chinese menu operation.

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

3. Features harmonic content measurement, capable of single-phase or three-phase simultaneous measurement.

4. Features resistive current fundamental peak output.

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

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