designed to aerate fish tanks. Clip the thermocouple to the PRT such that the junction is
near to the sensing element in the PRT (perhaps 1-2cm from the end) with nylon cable
ties and immerse the assembly in the oil.
There is only one reference junction sensor for all the channels, so you can use any
millisKanner channel for this check.

You can adjust the calibration of the millisKanner using the RJC Sensor Calibration
feature in the milliK to which it is attached. Before you can use this feature you must first
attach a calibrated thermocouple to one of the channels and configure the channel for
use with this thermometer (see milliK manual for details). If you measure the ambient
temperature with a calibrated PRT and use this as the “known” temperature for the
calibration, you can use a good quality, uncalibrated thermocouple since the difference
between ambient temperature and the reference junction will be very small, so any error
will be insignificant. If you use an uncalibrated thermocouple, make sure that you set the
thermocouple ‘Conversion’ to the thermocouple type used:
