9.3.12

Total performance

Similar to DIN 16086
In the range -10 … 60 °C (14 … 140 °F):
0.42% of the set span (TD 1:1)
The total performance accuracy includes the measuring error
(non-linearity including hysteresis and non-reproducibility), as
well as the thermal change in the ambient temperature as
regards the zero signal and span.
