Accuracy

0.1 %

Deviation

I m ≥ 1 mA: ±0.1 % of R m or ± 0.1 Ω (the larger value is applicable) I m < 1 mA: accuracy reduces in proportion to I m . e. g. I m = 0.1 mA: ± 1 % of R m or 1 Ω (the larger value is applicable).

Influence of ambient temperature

I m ≥ 1 mA, R m ≥ 100 Ω: 0.01 %/K in the range -20 ... +70 °C (-4 ... 158 °F) I m < 1 mA or R m < 100 Ω: temperature stability reduces in proportion to I m or R m
