[1]Includes calibration uncertainty and 100 hr drift.
[2]Three thermal cycles from min to max temp, includes hysteresis, 95 % confidence (k=2)
[3]After 100 hrs at max temp, 95 % confidence (k=2)
[4]Temperatures outside this range will cause irreparable damage. For best performance, transition junction should not be too hot to touch.
[5]Per ASTM E 644
