Collecting Data with the Thermistor
Sensor
1. Follow the Procedure under “Connecting the Thermistor
Sensor to a Computer Interface.”
2. Open DataStudio and double click “Create
Experiment.”
3. Click the Setup button to open the Experiment Setup
window.
4. In the Sensors list, scroll to the Thermistor Sensor icon
and drag it to an analog channel on the picture of the
interface (the same channel in which you have the
sensor connected).
5. Double click on the Thermistor icon, click in the
Measurement tab, select a measurement type, and click
OK.
6. Open a Graph display and click the Start button to
begin collecting data.
Sensor Calibration
The Thermistor Sensor is factory calibrated. However,
the unit may be calibrated or have the calibration
verified. Resistors with a known value are required for
calibration. For more information about calibration,
see the DataStudio online help.
Sensor Accuracy and Resolution
The resolution and accuracy of resistance
measurements with the Thermistor Sensor are directly
related to the resolution and accuracy of the
ScienceWorkshop interface used. For example, if the
interface has a resolution and accuracy of ±0.005V,
the resistance measurement will have an accuracy of
36,000 ohms/V times 0.005V or ±180 ohms.
Connecting a Temperature Probe to
the Thermistor Sensor
1. To connect a Temperature Probe to a Thermistor
Sensor, insert the stereo plug on the probe into the
stereo jack on the top of the sensor.
Note: Probes without stereo jacks cannot be connected
to the Thermistor Sensor.

*Note: These specifications are dependent on the quality of
the thermistor used with the CI-6527A Thermistor Sensor
Amplifier. The specifications are typical of the 10K and
100K thermistor used in PASCO temperature probes and
physics apparatus (at 25º
C).
