(6) Line-Segment Function Output Setting (Function code “A”)
Analog signals can be output in the form of line-segment function. The setpoint value (%) of the
function for a span (mg/l) in the output range is the break point corresponding to 50 % of the
output signal (4 to 20 mA or 1 to 5 V) span. The setting range is 0 to 100 %. Figure 5.9 shows a
setting example.

Output : 4 to 20 mA
Break point setting : 40 % (2 mg/l)
Figure 5.9 Example of Line-Segment Output
If the setpoint is specified at 50 %, the output becomes linear. Also, if set to 0 % or 100 %, the
output is as shown in Figure 5.10.
