AM8010 Precision Thermometer User's Guide
Apply the calculated A and B，together with the new low
temperature data to：
Then C value can be calculated.
5. Key in the A，B，C and R0 to AM8010. The system
calibration is done.
6. Turn off the power after calibration.
7.2.2 Calibration of PRT (high precision 100 ohm or standard 100
ohm Platinum Resistance Thermometer with temperature
coefficient α=0.003925（W
1. Turn off power of AM8010, set it to Measurement Mode.
(See Chapter 4.1
2. Connect the sensor to AM8010. Power on AM8010, and
put the sensor into temperature bath or fixed point cell.
3. Choose more than three temperature points to measure
based on the sensor's temperature range and ITS-90
standard.
4. These measurement data can be applied to the calculation
of sensor's temperature coefficients based on ITS-90
formula.
For example, the following data are acquired between 0ºC
to 300ºC.
