Move the thermometer and the Fast Response Temperature Probe to the container of hot water. When the
“Sensor Value” stabilizes, highlight the Standard Value and enter the temperature from the thermometer in the
text box. Click or touch “Set Calibration”. Check the New Calibration and click or touch “OK” to return to the
graph display.
Theory of Calibration
One of the functions of the PASCO Data Collection Software (SPARKvue or PASCO Capstone) is to take the
stream of raw data from a sensor and transform it into the calibrated data that you see in the Graph, Table, and
other displays. If you do not calibrate a sensor yourself, the software uses a default calibration that is loaded when
the sensor is connected.
You can think of the software as taking in raw data and outputting calibrated data. When you perform a calibration,
the software redefines the linear equation that transforms the raw input data into the calibrated output data. The
linear function is of the form:
Calibrated Output = Slope x Raw Input + Offset
Or:
Raw Input = (Calibrated Output- Offset)/Slope
Highlight the Standard Value and enter the
thermometer temperature
