- CONT: the output reacts
according to the settings
made within menu CAL mA
- 22 mA: the output imme-
diately delivers a 22 mA
current (disappears as soon
as the pressure is again
within the range)
example of the behaviour of
the transistor outputs (OUT)
and the 4-20 mA output
(mA) depending on the
mode selected within CAL
FAIL and/or CAL OUT, and
depending on the measured
pressure.
Assuming:
- a 4 mA current corresponds
to OLO
- a 20 mA current corres-
ponds to OHI
- the transistor outputs react
according to the window
mode.
