(1) Repeatability is the ability to reproduce a reading when the measured temperature is applied consecutively, under the same conditions.
(2) One-shot mode setup, 1 sample per minute for 24 hours.
(3) Long-term drift is determined using accelerated operational life testing at a junction temperature of 150°C.
