Use the CT command to perform a 1-point or 2-point temperature (T) calibration. 1-point calibration adjusts the offset for the measurement, 2-point calibration adjusts offset and gain.
CT [reference]<cr>
When performing a 1-point calibration, you need to place the probe in a single temperature reference and wait for 20 … 40 minutes for the temperature to stabilize. To apply the adjustment, enter the CT command with the reference temperature as a parameter.
Example: 1-point calibration
ct 23.5
OKGiving the command without parameters starts the 2-point calibration. Remember to allow the temperature to stabilize for 20 … 40 minutes after changing the reference. The first reference point must be smaller than the second point, and the difference between the reference points must be more than 30 °C. To update the measured value while the command is running, press enter without inputting a value.
