Calibration of the complete system is the most accurate system since it incorporates the probe error
in the calibration to offset it. As a result, the probe must be mobile and two calibration baths
stabilised at precisely known temperatures are required. This method is reserved for the sample
probe (the other probes internal to the instrument are not mobile and their calibration does not
require such accuracy).
Calibration using two points adjusts the high point and the low point and defines a line interpolated
between them. Each reading above and below the calibration points will be an extension of the
interpolation line. For this reason, it is preferable to calibrate with two points as far away as possible
as shown in the example below.
