Product Description

This instruments is controlled by intelligent microcontroller chip,with high accuracy and high reliability;it can be used to measure grounding resistance of various power facilities wiring,electrical equipment,lightning protection equipment and other grounding devices, and it can also measure ground voltage.
Function:
* Backlight an battery detection function
* Data holding
* "OL"Stands for over range
* Double insulation or reinforced insulation safety structure
* When measuring ground resistance, if C or E end of test lead is not in good contact,"...Ω"warning appears on LCD
* It can be used for precise three-wire measurement or simple two-wire measurement.
