AM8010 Precision Thermometer User's Guide
1. Turn off power of AM8010, make sure it is at
Measurement Mode (see Chapter 4.1 for details).
2. Connect the sensor to AM8010. Power on AM8010,
and put the sensor into temperature bath or fix point
cells.
3. High temperature range calibration: three temperature
points are needed which are ice point (triple points of
water), temperature close to upper limit, and a point in
between. Note down the measurement results at all
these three points.
For example，the following three temperature points
from 0ºC to 300ºC are selected and after the
calibration, the following group of data are acquired.
Standard
temperature t
0ºC
150ºC
300ºC
Apply the above data to ： R(t)=R(0ºC)*(1+At+Bt
then parameters A and B can be calculated.
4. Low temperature range calibration：Measure another
temperature point that is close to the probe's lower
temperature limit using AM8010.
For example, the following data is acquired：
AM8010 measured R(t)
resistance value
R（0ºC）
R（150ºC）
R（300ºC）
Standard AM8010 measured R(t)
temperature t resistance value
-60ºC R(-60ºC)
