| Calibration |
Calibration not included; NVLAP-accredited calibration optional, lab code 200348-0. Please see calibration uncertainty table and its explanation of changeable uncertainties.
|
[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, 95 % confidence (k=2)
[3] After 100 hours 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.
