◆ Meet the needs of various measured ground resistance environment: measure the grounding resistance by using two kinds of measurement methods: two-pole AC, two-pole DC, three-pole, four-pole, current clamp selection method, and double-clamp head without auxiliary pole method.

◆ Double jaws without auxiliary pole method to quickly measure ground loop resistance

◆ Quadrupole method can directly measure soil resistivity

◆ One-button operation test is simple

◆ Automatic Frequency Control (AFC) – Automatically identify interference and select the appropriate measurement frequency to minimize the effects of interference and provide a more accurate ground resistance value. Also select: 94Hz, 105Hz, 111Hz, 128Hz four frequencies

◆ Test voltage 48V/20V optional

◆ Online measurement does not need to be disconnected from the load

◆ Automatically measure interference voltage and leakage current, and have test line resistance compensation function

◆ Test the numerical average function to smooth the resistance or current measurement

◆ Unique only interface prompt function: Each grounding resistance test method uses different test wiring methods, the instrument interface will automatically light up the prompt light, so that testers who have not received training can also master the instrument operation very quickly.

◆ Unique interface contact good prompt: plug in the corresponding test line, only the position indicator light will be extinguished

◆ Measure data storage function, can store 100 sets of measurement data, and can be uploaded to PC through USB interface for display analysis, output test report

◆ Large-screen LCD display with backlight, and equipped with: limit value alarm function, clock display function, automatic shutdown function

◆ Flexible power supply mode, the instrument can choose three kinds of power supply modes: dry battery, rechargeable battery and mains supply.
