## Overview

The VC4105A Earth Resistance Tester is a professional-grade, portable device designed for precise measurement of earth resistance (up to 2000Ω) and grounding voltage (up to 750V AC). Featuring a backlit LCD for clear readings, durable dust and moisture-resistant construction, and a comprehensive accessory kit, it empowers electricians and engineers to quickly verify grounding systems with confidence. Powered by 8 AA batteries or an external adapter, it’s optimized for field use and ensures reliable performance in diverse environments.

## Description

EONE Science and Technology Co., Ltd. is the manufacturer of electronic measuring instruments, including: oscilloscope, multimeter, clamp meter, ground resistance r, insulation resistance meter, etc. The VC4105A is a professional portable resistance tester with accuracy of ±(1.0%+0.1Ω), more convenient and cost effective for users. It can measure the resistance and voltage of the grounding system of the power supply system, electrical equipment, lightning protection equipment, etc. Product features: ① Product size: 18.5 x 11.5 x 6.5 cm, weight 0.7 kg. ② Display: 1.25 x 2.0 inch LCD screen. ③Max Reading: "1999" ④ Overbeach indicator: only the most significant "1" when exceeding the limit ⑤Power Supply: AA5# LR6 alkaline battery (1.5V) x 8 sections (can also be powered by external power adapter) When the voltage is insufficient, there is an indication of undervoltage. Operating environment: temperature from 0°C to 40°C, relative humidity from 30% to 85% RH Measuring range: Earth resistance measurement range: 20Ω/200Ω/2000Ω (Resolution: 0.01Ω) Grounding Voltage Measuring Range: AC 750V (Resolution: 1V) (For more information, please click on the product images to see details). Package includes: 1 x VC4105A Ground Resistor 1 x practical carry bag. 1 x English User Manual 2 x Auxiliary grounding nails 2 x Auxiliary Test Cable with Clip (includes 1.5m red line, 1.5m green line) 3 x Standard Test Cable (Includes: 5m Green Line, 10m Yellow Line, 15m Red Line) 8 x AA batteries

Review: The product was good and worked as expected
Review: Simple tool for a simple job. I used it to determine that my ground rod to my service was obviously cut off and was not presenting < 25 ohms so I added a second ground rod and measured again and in my case, I had to add a third due to the shallow soil. This could save you time and money if you are an elecrician as you can determine if a single ground rod meets the standard of 25 ohms or less before you get your inspector telling you.
