Introduction and Application
This instrument 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. (Note: This instrument is not suitable for harsh outdoor environmental conditions, such as raining, lightning, etc.)
Features
Backlight a 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,"...Warning appears on LCD.
It can be used for precise three-wire measurement or simple two-wire measurement.
