Note1
|
Accuracy is a difficult term when used to describe a
resistance thermometer. The simplest way to derive
"accuracy" is to combine the probe drift specification and
calibration uncertainty with readout accuracy at a given
temperature. |
|
Note2 |
Three thermal cycles from minimum to maximum temperature,
includes hysteresis, 99.9% confidence. |
|
Note3 |
After 100 hours at maximum temperature, 99.9% confidence. |
|
Note4
|
Temperatures outside this range will cause irreparable damage.
For best performance, transition junction should not be too hot to
touch. |
|
Note5 |
Per ASTM E 644 |

Note: Calibration uncertainties depend on the uncertainties of
the lab performing the calibration. Subsequent calibrations of
this probe performed with different processes, at different
facilities, or with changed uncertainty statements may state
different uncertainties. |
