Hand held grounding resistance tester DY2571X

Product introduction

DY2571S digital grounding resistance tester is designed and manufactured according to the new lightning protection grounding resistance detection standard. The short circuit test current is up to 20mA. The precision 3-wire method or simple 2-wire method is used to measure the grounding resistance. FFT (Fast Fourier Transform) technology is introduced and digital filtering algorithm is adopted. It has unique anti-interference ability and environmental adaptability, and has strong consistency in repeated tests. It is widely used in the measurement of grounding resistance and grounding voltage of electric power, telecommunications, meteorology, oil fields, buildings, lightning protection and industrial electrical equipment.

The instrument has a unique line resistance calibration function, which is more accurate for measuring the field low value grounding resistance, and can avoid the error caused by the change of line resistance when the test line is used for a long time; It can avoid error caused by incomplete insertion of test line into instrument interface or poor contact; It can avoid errors caused by user replacement or lengthening of test line.

The instrument is composed of host, test line, auxiliary grounding rod, data software, communication line, etc. The host adopts an integrated hand-held design, which features low density, light weight, strength, stiffness, hardness, wear resistance, heat resistance and insulation performance, ensuring high accuracy, stability and reliability of various environmental tests. The host has a large LCD display with backlight and bar graph indication, which is clear at a glance. It can store 300 groups of data. Through data software, historical data reading, viewing, saving, reporting, printing and other functions can be achieved.
