Product Overview
GD7020 handheld wireless zinc oxide tester is only used to test the full current and resistive current of Zinc fluoride arrester. According to the comparison of test parameters, it can be judged whether there are dangerous defects such as insulation damp and valve aging inside the equipment. It can be used for online live testing as well as production process inspection.
Functional characteristics
♦ The instrument adopts a 7-inch color touch screen with a clear interface.
♦ High precision sampling and processing circuits, advanced Fourier harmonic analysis technology, make data more reliable.
♦ With harmonic content testing function, it can measure single-phase or three-phase simultaneously.
♦ Equipped with resistive current fundamental peak output function.
♦ The instrument is equipped with a built-in large capacity memory. It can store a large amount of information such as test data, waveforms, harmonics, etc,
♦ 200 sets of data information are saved in a cyclic update mode.
♦ The instrument is equipped with a USB flash drive interface, which can store any set of test records.
♦ The instrument voltage test line is equipped with a safety wire to prevent incorrect connection, and the instrument voltage and current plug has a function of preventing incorrect insertion.
♦ The instrument is equipped with a wireless module that can perform voltage wireless collection and cooperate with the host for wireless measurement.
♦ The instrument has a built-in high-precision Real-time clock, which can be used for date and time calibration.
♦ The instrument has printing function and can be equipped with an external printer for printing.
