Description and settings
3.3.0 CUR.OUTP. I Submenu 3.3.0 Current output I
3.3.1 FUNCTION I Function, current output I
• OFF (switched off)
• F/R IND.
(F/R indication, e.g. for F)
• 1 DIR. (1 flow direction)
• I
(Forward / Reverse flow,
e.g. in 0 - 20 mA range:
F=10 - 20 mA and R=10 - 0 mA)
• 2 DIR. (Forward/Reverse flow,
F/R-measurement)
• SP. SOUND (sound velocity)
3.3.2 RANGE I Range for current output I, see
Sect. 5.7.2
• 0 - 20 mA
• 4 - 20 mA
• OTHER RANGE
(see Fct. 3.3.3, 3.3.4 + 3.3.5)
3.3.3 I 0 PCT. Current for 0% flow (I
0%
)
(appears only if OTHER RANGE
set under Fct. 3.3.2).
Value: 00 to 16 mA
3.3.4 I 100 PCT. Current for 100% flow (I

set under Fct. 3.3.2).
Value: 04 - 20 mA
(value must be at least 4 mA
greater than that of Fct. 3.3.4).
3.3.5 I MAX mA Current limitation (I
max
)
see Fct. 5.7.2

(appears only if YES set
under Fct. 3.3.7)
Value: 02 - 20 PERCENT of Q
100%
(Fct. 3.1.1), value must be greater
than that of Fct. 3.3.8.
