[1] Includes short-term repeatability and 100 hr drift. Calibration will add additional uncertainties [2] Three thermal cycles from min to max temp, includes hysteresis, 99.9 % confidence (k=3) [3] After 100 hours at max temp, 99.9 % confidence (k=3) [4] Temperatures outside this range will cause irreparable damage. For best performance, the transition junction should not be too hot to touch [5] Per ASTM E 644 |
