Additonal error because of probe- and auxiliary earth typ. electrode resistance Measuring error of RH and RS Measuring time Minimal current in single branch to be measured Max. interference current through transformer Typ. of 10 % of RETOTAL + RS + RH Typ. 8 sec. with a fixed frequency 30 sec. max. with AFC and complete cycle of all measuring frequencies 0.5 mA With transformer (1000:1) 0.1 mA With transformer (200:1) 3 A With a transformer (1000:1) Resistance measurement (R~) Measuring method Measuring voltage Short circuit current Measuring frequency Current and voltage measurement 20 V ac, square pulse > 250 mA ac 94, 105, 111, 128 Hz selected manually or automatically (AFC) Measuring range 0.020 Ω to 300 kΩ Display range 0.001 Ω to 2.999 Ω 3.0 Ω to 29.99 Ω 30 Ω to 299.9 Ω 300 Ω to 2999 Ω 3.0 kΩ to 29.99 kΩ 30.0 kΩ to 299.9 kΩ Resolution 0.001 Ω 0.01 Ω 0.1 Ω 1 Ω 10 Ω 100 Ω Accuracy ± (2 % of rdg + 2 digit) Measuring time Max. interference voltage Max overload typ. 6 sec. 24 V, with higher voltages measurement will not be started Urms max. = 250 V Operating errors ± (5 % of rdg + 5 digit) Resistance measurement (R ) Measuring method Open circuit voltage Short circuit current Formation of measured value current- voltage measurement as per IEC61557-4 possible 20 V dc 200 mA dc 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 to 3 kΩ Display range 0.001 Ω to 2.999 Ω 3.0 Ω to 29.99 Ω 30.0 Ω to 299.9 Ω 300 Ω to 2999 Ω Resolution 0.001 Ω 0.01 Ω 0.1 Ω 1 Ω Accuracy ± (2 % of rdg + 2 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 Operating error ± (5 % of rdg + 5 digit) MyFlukeStore Shop for Fluke products online at: www. .com 1.877.766.5412
