Calibration NIST-traceable calibration
[1]
"Accuracy" is a difficult term when used to describe a resistance thermometer. The simplest way to de-
rive basic “accuracy” is to combine the probe drift specification and calibration uncertainty with readout
accuracy at a given temperature.

Three thermal cycles from min to max temp, includes hysteresis, 99.8 % confidence

After 100 hrs at max temp, 99.8 % confidence

Temperatures outside this range will cause irreparable damage. For best performance, transition junc-
tion should not be too hot to touch.
