Accuracy
Measurement accuracy is expressed as ± (% of reading + LS digit value) with auto zero and auto calibration active. Accuracy varies by digit setting and integration time (1 PLC, 5 PLC, 100 PLC). Temperature coefficient for 4-wire Ω measurements: ± (% of reading + LS digit value)/°C from 0°C to +40°C. Two-wire Ω measurements add 0.02 Ω/°C plus maximum 0.2 Ω offset versus 4-wire measurement.
