Introduction

HM2571B is a high-end multifunctional clamp type earth resistance meter. With USB communication interface, storage data can be uploaded to the computer, through software analysis, report, printing and so on. the meter could test 40A leakage current.supports multi-parameter on-screen display function, can display grounding resistance and ground leakage current at the same time, which is more practical, convenient and efficient.

The instrument is widely used in grounding resistance measurement and loop resistance measurement of electric power, telecommunications, meteorology, oil field, construction and industrial electrical equipment. When measuring the grounding system with loop, it is not necessary to disconnect the grounding down conductor, and no need auxiliary electrode, which is safe and fast.

Mainly performance

1.Short boot time, start immediately into the test.

2.Using the most advanced processing algorithms and digital integration technology.

3.Add real-time clock function to display real-time time of present test.

4.New design, panel operation with 6 buttons, better performance.

5.Sound and light alarm, with"beep—beep--beep --" alarm sound.

6.Increase the interference signal recognition indicator.

7.Variety of combination display mode, can choose resistance + current, resistance + time, current + time to display on screen.

8.Stored data: 999 group. Lower power consumption: Max running current not exceeding 50mA.

9.Rechargeable battery makes it more convenient to use.

10.Equipped with monitoring software，It has functions of online real-time monitoring, historical query, and software alarm setting, historical data reading, saving, and reporting. Historical data can optionally be saved in Txt text or Word format.
