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 value: with 4-pole measurement wires on H, S, ES can be extended without additional error. Resistances >1 Ω in wire E can cause additional error of 5m Ω/Ω. Measuring Range 0.020 Ω 3 kΩ Display Range Resolution 0.001 Ω ... 2.999 Ω 3.0 Ω ... 29.99 Ω 30.0 Ω ... 299.9 Ω 0.001 Ω 0.01 Ω 0.1 Ω 300 Ω ... 2999 Ω 1 Ω Intrinsic Operating Error Error ±( 2 % of m.v. +2 digit) ±( 5% of m.v. +5 digit) Measuring sequence: Measuring time: Max. interference voltage: Max inductivity: Max. overload: approx. 2 measurements/s typ. 4 sec. incl. reversal of polarity (2 pole or 4 pole) ≤ 3 V AC or DC, with higher voltages measurement will not be started 2 Henry Urms = 250 V 19
