AM8010 Precision Thermometer User's Guide
The following sections illustrate System Calibration procedure with
two types of sensors "IPRT" and "PRT".
7.2.1 Calibration with IPRT (high precision 100 ohm or industrial
100 ohm Platinum Resistance Thermometer with α=0.00385)
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.
Apply the above data to: R(t)=R(0ºC)*(1+At+Bt
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:
