Calibrate a temperature sensor

Calibrate the reading of a temperature sensor.

The following procedure will allow you to calibrate any dedicated PASCO temperature sensor which can connect to Capstone, including the Wireless Temperature Sensor (PS-3201), Wireless Temperature Link (PS-3222), and PASPORT Temperature Sensor (PS-2125).

Before you start

Calibrating a temperature sensor will require the following components:

  • An ice water bath
  • A container of hot water
  • A thermometer

Calibration

  1. Connect the sensor to Capstone.
  2. Select Calibration from the Tools palette.
  3. Select Temperature from the dropdown box, then click Next.

  4. Ensure that Two Standards (2 point) is selected from the list of calibration types, then click Next.

  5. Place the temperature sensor and thermometer into the container of hot water. Wait for both the temperature reading and the thermometer measurement to stabilize.

  6. Using the thermometer, determine the temperature of the hot water. Enter this value into the Standard Value box, then click Set Current Value to Standard Value.
  7. Remove the thermometer and temperature sensor from the hot water container, wipe them both dry, and place them in the ice water bath. Wait for the temperature reading and thermometer measurement to stabilize.

  8. Using the thermometer, determine the temperature of the ice water. Enter this value into the Standard Value box, then click Set Current Value to Standard Value.
