General specifications Measuring functions 3-pole earth ground resistance, 2-pole ac resistance of a conductor, Interference voltage Intrinsic error Refers to the reference temperature range and is guaranteed for one year Measuring rate 2 measurements/second Battery[1] One 9 volt alkaline (LR61) Battery condition LO-BAT is displayed if voltage drops below 6.5 V Voltages Between jacks H/C2 and E/C1: 250 Veff maximum (effective voltage) Between jacks S/P2 and E/C1: 250 Veff maximum Climatic class VDE/VDI 3540 RZ (conforming to KWG as per DIN 40040, 4/87) Temperature performance[2] Working: -10 °C to +50 °C (+14 °F to +122 °F) Operating: 0 °C to +35 °C (+32 °F to +95 °F) Storage: -20 °C to +60 °C (+68 °F to +140 °F) Reference: +23 °C ± 2 °C (+73 °F ± 4 °F) Temperature coefficient ± 0.1 % of range per degree Kelvin Safety IEC/EN 61010-1, 600 V CAT II, pollution degree 2 Dimensions 113 mm x 54 mm x 216 mm (4.5 in x 2.1 in x 8.5 in), including holster Weight 850 g (1.9 lb), including standard accessories, volume approximately 600 cm3 Note: [1]If the tester is not going to be used, or is being stored for a long period, remove the battery and store separately from the tester to avoid damage from battery leakage. Note: [2]The four temperature ranges for the tester exists to satisfy European Standards requirements; the instrument can be used over the full working temperature range by using the temperature coefficient to calculate accuracy at the ambient temperature of use.
