DESCRIPTION
The GRT300 is a comprehensive 4-wire earth ground resistance tester kit. It measures earth ground resistance across four autoranging scales (2Ω, 20Ω, 200Ω, 2000Ω) with a basic accuracy of ±(2%rdg+3d) and can also measure AC earth voltage up to 300VAC. The device utilizes a test current of less than 2mA at a frequency of 820Hz for accurate readings. Key features include 2, 3, and 4-wire testing capabilities, automatic I (current) and P (potential) spike checks, a large dual-line LCD, and a test hold function for easy operation. This complete kit includes all necessary hardware, such as test leads, auxiliary earth bars, and a hard carrying case, making it ideal for field testing applications.
