Transmission characteristics |
||
| Accuracy | 0.1% | |
| Deviation |
I m ≥ 1 mA: ±0.1% of R m or ±0.1 Ω (whichever is greater) I m < 1 mA: accuracy decreases proportionally to I m . eg I m = 0.1 mA: ±1% of R m or 1 Ω (whichever is greater). |
|
|
|
The influence of ambient temperature |
I m ≥ 1 mA, R m ≥ 100 Ohm: 0.01%/K in the range of -20 ... +70 °C (-4 ... 158 °F) I m < 1 mA or R m < 100 Ohm: thermal stability decreases proportionally to I m or R m |
