Huazheng HZ-20A-I Portable Handheld Zinc Oxide Arrester Tester
I. Features
1.Seven-inch high-brightness color touch LCD display, ensuring clear visibility even under strong light. It features full touchscreen operation and supports easy switching between Chinese and English.
2.High-precision sampling and processing circuit, along with advanced Fourier harmonic analysis technology, ensuring more reliable data.
3.Harmonic content testing function, capable of measuring both single-phase and three-phase systems simultaneously.
4.Includes a function for measuring the peak output of the resistive current fundamental wave.
5.The instrument has a built-in large-capacity memory, capable of storing a large amount of recorded information such as test data, waveforms, harmonics, etc. It can save up to 200 sets of measurement records, with the data saved in cyclic update mode.
6.Equipped with a USB interface for storing test records, with storage capacity limited by the size of the USB drive.
7.The instrument’s voltage test leads are equipped with fuses to prevent incorrect connections, and the voltage and current plugs feature a mechanism to prevent incorrect insertion.
8.The instrument includes a wireless module, allowing for wireless voltage measurement in conjunction with the host for remote data collection.
9.The instrument has a built-in high-precision real-time clock, enabling date and time calibration.
10.The instrument can be connected to an external printer for printing measurement data, supporting paperless office operations (optional).
11.The instrument is equipped with a built-in large-capacity lithium battery, providing up to 6 hours of continuous operation.
