(circle) with the
value on the calibration solution.
Pressing the
Nom. val.
button (circle)
causes a numerical entry field to appear
where the nominal value can be adjusted.
5.2: Wait until the temperature value (circle) is
stable.
The recalibration is performed only if
the values were stable over the last 3
minutes.
