Auto Detect UF works in such a way that MULTICAL® 803, during startup, automatically collects the correct
information about meter factor and qp from the connected ULTRAFLOW® X4 flow sensors. MULTICAL® 803 adapts
its configuration to the values that are received from ULTRAFLOW® X4. Auto Detect UF is initiated when the
calculator top and base are separated and reassembled.

Note that MULTICAL® 803 has a built-in engagement delay of up to 20 seconds to ensure that all plug connections between
calculator top and base are established before a detection of Pt sensors and/or ULTRAFLOW® X4 is initiated.

If Auto Detect Pt for the temperature sensors is switched on, the text in the upper right corner of the display will alternately
show
UF
and
Pt
. See more about Auto Detect Pt in paragraph 7.7.
