Immediately following switching-on, the ULTRAMAT 23 tests the
display elements. During this test, all elements light up simulta‐
neously for approx. five seconds.
The adjacent display subsequently appears with the remaining
warm-up period which is counted down in seconds to 00:00
(minutes:seconds).
In the first 5 minutes of the warm-up phase, the 4 mA value is
always transferred over the analog interface and the 'Function
control (FCTRL)' status is set. This does not represent an error.
