This command is notavailable on the HMP110T.CRHCLRExample:crhclrOKCalibrate Temperature MeasurementUse the CT command to perform a one-point or two-point temperature(T) calibration. One-point calibration adjusts the offset for themeasurement, two-point calibration adjusts offset and gain.CT [reference]When performing a one-point calibration, you need to place the probe ina single temperature reference and wait for 20 – 40 minutes for thetemperature to stabilize. To apply the adjustment, enter the CT commandwith the reference temperature as a parameter.Example: one-point calibrationct 23.5OKGiving the command without parameters starts the two-point calibration.Remember to allow the temperature to stabilize for 20 - 40 minutes afterchanging the reference. The first reference point must be smaller than thesecond point, and the difference between the reference points must bemore than 30 ºC. To update the measured value while the command isrunning, press enter without inputting a value.Example: two-point calibrationctT : 22.03 Ref1 ? 22Press any key when ready ...T : 55.12 Ref2 ? 55OK
