					Earth/Ground Tester
					Specifications
Resistance Measurement (RF)
Measuring method:			current- voltage measurement as per IEC61557-4
			possible
Open circuit voltage:			20 V DC
Short circuit current:			200 mA DC
Formation of measured			with 4-pole measurement wires on H, S, ES can
value:			be extended without additional error.
			Resistances >1 Ω in wire E can cause additional
			error of 5m Ω/Ω.
