I. Product Introduction

 

HT3000 digital grounding resistance tester, also known as the three-wire grounding resistance tester, grounding resistance meter, etc., is a commonly used instrument for measuring common grounding resistance meters.It uses a large LCD gray screen backlight display and microprocessor technology to meet the two-wire, three-wire test resistance requirements.Suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on.The instrument has the characteristics of precise, fast, simple, stable and reliable.

HT3000 digital grounding resistance tester is controlled by a microprocessor and can automatically detect the connection status of each interface and the interference voltage and interference frequency of the ground network, and with the function of testing the auxiliary grounding resistance, the measured grounding and auxiliary grounding resistance in the same screen display is clear at a glance.At the same time store 500 sets of data, resistance measurement range: 0.01Ω ~ 3000Ω, grounding voltage range: 0 ~ 100V. The online monitoring data can be monitored by the monitoring software. USB data can be uploaded to the PC and has unique functions such as numerical maintenance and intelligent alarm prompting.

HT3000 digital grounding resistance tester consists of host computer, monitoring software, test line, USB cable, and grounding pin. It has the functions of reading, checking, saving, reporting and printing of historical data.
