Description
Menu item
ON
Auto recalibration to uncovered probe
.
It is possible to commission an already filled silo
(covered probe). A proper calibration is not
possible with covered probe. A solution is to do
an auto calibration as soon as the silo becomes
empty (uncovered probe).
To do this, set Auto recalibration to
ON
and do a
push-button calibration with a covered probe
(press and hold the
CAL
button for 3 seconds).
The level switch will recalibrate (as an uncovered
probe) when the measured capacitance is 50% of
the sensitivity setting (menu item
D
) for more
than two minutes.
Do not set to
ON
if excessive solids material
build-up is present, since this build-up may
decrease the measured capacitance and cause
an incorrect calibration.
