5.3.8 Adjusting the RJC Sensor Calibration
Before you can use the RJC calibration adjustment feature you must first attach a calibrated
thermocouple to one of the channels and configure the channel for use with this thermometer
(see section 3.3.4). If you measure the ambient temperature with a calibrated PRT and use
this as the “known” temperature for the calibration (see section 5.2.6 for details), you can
reasonably use a good quality, uncalibrated thermocouple (the difference between ambient
temperature and the reference junction will be very small, so any error will not be
significant). If you use an uncalibrated thermocouple, make sure that you set the
thermocouple ‘Conversion’ to the thermocouple type used:
