9.7.3 Surface increment
Surface probes withdraw heat from the measured surface immediately
after the initial contact. This makes the measurement result lower than
the true surface temperature without the probe (or the reverse if the
surface is colder than the environment). This effect can be corrected by
an increment in % of the reading.

The probe is connected to the testo 400.
