If the probe connects to a Thermistor Pod, the correct units will automatically display in LabChart.
A unit conversion is required if the probe connects to a Bridge Amp. As the probe’s sensor is non-linear, the Multipoint Calibration extension for LabChart is recommended. This extension can be downloaded from the Feature Manager in the LabChart Help menu. To calibrate the probe, place it in solutions of different known temperatures and record the voltage values in LabChart. Highlight the recorded data and choose the multipoint calibration option from the channel drop-down menu.
For each temperature, highlight a selection of the plateaued data and select the arrow on the left side of the dialog. This will enter the voltage value into the first box. Apply the relevant temperature in the right-hand box on the same line. When you have done this for each temperature, select the unit of choice (e.g. °C), select a suitable line fit, and then select Apply. Recordings made with your temperature probe will now read out the correct temperature.
