3.3.0 CURR. OUTP.I : set up analog current
output
3.3.1 FUNCTION I : Program the analog
current output
Select an output option using the key and press
to store:
2 DIR : Enables flow measurement in 2 direc-
tions(+ and -) without change
of
polarity in the output signal (Fig. D.3)
TRAN. TIME : Output signal is proportional to
the measured transit time of the
acoustic signal.
NOTE: this function requires:
- current setting at zero flow, Fct. 3.3.2
- current setting at full flow, Fct. 3.3.3
- transit time at full flow, Fct. 3.1.2
(see example in description of Fct. 3.1.2)
NO SIGNAL : Output signal indicates "signal loss".
OFF : No current output.
F/R IND. I : Output signal as flow direction
indication, 0% at + flow direction
and 100% at -flow direction
(fig. D.4).
1 DIR : Flow measurement in 1 direction
(+) only. (Fig. D.5)
I < I 0 PCT : Allows the output signal to drop
below the programmed value for
0% flow at negative (-) flow
direction. If 10 mA is programmed for
0% flow (Fct.3.3.2) and 20 mA for
100% (Fct. 3.3.3) then the output will
