Ambient temperature of TSX AEY 414
NOTE: Accuracies are given for 4-wire connections and include the errors and drifts of the source of the current, 2.5 mA (Pt100) or 0.55903 mA (Pt1000 or Ni1000).
The self-heating effect introduces no significant error to the measurement, whether the probe is in the air or in the water.

The self-heating effect introduces no significant error to the measurement, whether the probe is in the air or in the water.
The error at any temperature T can be deduced by linear extrapolation of the errors defined at 25 and 60°C following the formula :
