Measuring accuracy in case of scaling
Accuracy during scaling (digits) = measurement accuracy (digits) × multiplier + 2 digits (rounded up)
* Fractions rounded up
where the multiplier = scaling span (digits)/measuring span (digits).
Example For 1-5 V range (A/D integration time is 16.7 ms or more), measurement span of 1.000 to
5.000 V, and scaling span of 0.000 to 2.000
The measuring accuracy for 5 V input is as follows.
Measuring accuracy (1-5 Vrange) = ±(0.05% × 5 V + 3 digits) = ±(0.0025 V [3 digits] + 3
digits) = ±6 digits
Multiplier = {2000 digits (0.000 to 2.000)}/4000 digits (1.000 to 5.000) = 0.5
Thus, accuracy during scaling = ±(6 × 0.5 + 2) digits = 5 digits (rounded up)
Reference junction compensation accuracy
When measuring temperature greater than or equal to 0 °C and when input terminal temperature is
balanced
Type R, S, W, WRe: ±1.0°C
Type K, J, E, T, N, L, and U: ±0.5°C
Type B: Internal reference compensation is fixed to 0°C
