Product Details
Digital Earth Resistance Tester GT5105A Electrical Tools
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.)
Digital Earth Resistance Tester possesses the following features:
1. backlight and battery detection function.
2. data holding.
3. It can be used for precise three-wire measurement or simple
two-wire measurement.
4. When measuring ground resistance, if C or E end of test lead is
not in good contact, "---- Ω" warning appears on LCD.
5. "OL" stands for over range.
6. Double insulation or reinforced insulation safety structure.
1.1 Measurement range and measurement error
(under condition of 20℃ ± 5℃and≤75%RH)
Basic Function | Range | Accuracy | Resolution |
Ground resistance | 20Ω | ±(2%+10) | 0.01Ω |
200Ω | ±(2%+3) | 0.1Ω |
2000Ω | ±(2%+3) | 1Ω |
2000Ω (two wires) | ±(2%+5) | 1Ω |
Ground voltage | 200V | ±(2%+5) | 0.1V |
1.2 measurement method:
