CURR. CHARACT.
(694), (695), (696), (764)
Options Select curve of current output.
Options:
P01-xxxxxxxx-05-xx-xx-xx-009
Fig. 10: Illustration of current output curves
1 Linear: lower range value = 4 mA, upper range value = 20 mA
2 Bi-linear: lower range value = 4 mA, center or zero = 20 mA,
upper range value = 4 mA
3 Linear inverse: lower range value = 20 mA, upper range value = 4 mA
4 Bi-linear inverse: lower range value = 20 mA, center or zero = 4 mA,
upper range value = 20 mA
LRV Lower Range Value
URV Upper Range Value
I Current
p Measured value (pressure)
The 3-digit ID number on the onsite display depends on the MEASURING MODE
selected:
– (694): MEASURING MODE "Pressure"
Factory setting:
Linear
OUTPUT FAIL MODE (388)
Entry Select the current value in the event of an alarm.
In the event of an alarm, the current assumes the current value specified with this
parameter.
Options:
• Max. alarm (110%): can be set between 21...23 mA
• Hold meas. value: last measured value is kept.
• Min. alarm (–10%): 3.6 mA

See also this table SET MAX. ALARM and Operating Instructions BA00412P,
Section "Configuring current output for an alarm".
Factory setting:
Max. alarm 110% (22 mA)
ALT.CURR.OUTPUT (597)
Options Set current output if sensor limits undershot or overshot.
Options:
• Normal: the current output assumes the value set via the OUTPUT FAIL MODE and
SET MAX. ALARM parameters.
• NAMUR:
– Lower sensor limit undershot (E120):
Current output = 3.6 mA
– Upper sensor limit overshot (E115): current output assumes the value set via the
SET MAX. ALARM parameter
Factory setting:
Normal
