6 Sensor Parameters Input/Adjustment

AM8010 supports two types of sensors: IPRT and PRT。
IPPT: high precision 100 ohm Platinum Resistance Thermometer or
Industrial 100 ohm Platinum Resistance Thermometer with
temperature coefficient of α=0.00385. The temperature is
calculated based on CVD formula. Users can input/adjust following
parameters of an IPRT: R0, A, B and C.
PRT: high precision 100 ohm Platinum Resistance Thermometer or
100 ohm standard Platinum Resistance Thermometer (SPRT) with
temperature coefficient of α=0.003925 (W
temperature is calculated based ITS-90 formula. Users can
input/adjust the following parameters:
 Rtp: the sensor's triple point of water.
 a4, b4: ow temperature range parameters.
 a, b, c: high temperature range parameters ( for some type of
sensors, b and c may equal to 0. Refer to ITS-90 for details).
After users input/adjust the correct parameters the sensor type is
displayed on the LCD of AM8010 and the parameters are used in
the calculation.
Note: Users need to set the parameters corresponding to the sensor
to get the optimal measurement. These parameters can be obtained
from qualified calibration institutes.
The detailed procedure to set the sensor type and parameters are as
follows:
1. Power off AM8010. Install batteries in the AM8010, or
connect AM8010 to a power adapter or a running computer
USB interface. Make sure each battery has enough power. It is
suggested to use new batteries for parameter setting or
calibration.
2. Set the Mode Switch to Measurement Mode. Refer to
4.1Mode Switch Setting.
