Introduction
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.)
Functions
backlight and battery detection function.
data holding.
It can be used for precise three-wire measurement or simple
two-wire measurement.
When measuring ground resistance, if C or E end of test lead is
not in good contact, "---- Ω" warning appears on LCD.
"OL" stands for over range.
Double insulation or reinforced insulation safety structure.
