Specifications
4-Terminal Earth Resistance & Soil Resistivity Testers
Item	Range	Accuracy	Resolution
Earth/Ground Resistance	0Ω ~ 6.99Ω	±(3%+6digits)	0.01Ω
	7.9Ω ~ 49.9Ω	±(2%+3digits)	0.1Ω
	50Ω ~ 299.5Ω	±(2%+3digits)	0.5Ω
	300Ω ~ 1500Ω	±(2%+3digits)	1Ω
Maximal earth resistance at H-end: Rcmax=(0-100Re) and 50KΩ less value
Maximal ground resistance at S-end: Rpmax=(0-100Re) and 50KΩ less value
Additional measurement error of Rxmac and Rpmax: ±(3%+10digits)
