| Calibration | |
| [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, transition junction should not be too hot to touch. [5] Per ASTM E 644 | Calibration Uncertainty for accredited† calibration |
| Temperature | Expanded Uncertainty (k=2) |
| –197 °C | 0.025 °C |
| –80 °C | 0.025 °C |
| –38 °C | 0.025 °C |
| 0.01 °C | 0.025 °C |
| 156 °C | 0.030 °C |
