There are four DC output signal pins—two pins per output. For
polarity, see Table 3-1. The outputs are:
0–1 VDC % of Range:
0–1 VDC Range ID:
4–20 mA DC % Range: Current increases linearly with
4–20 mA dc Range ID:

Voltage rises linearly with increasing
concentration, from 0 V at 0
concentration to 1 V at full scale. (Full
scale = 100% of programmable range.)
0.20 V = Low Range
0.5 V = Medium Range
0.80 V = High Range
concentration , from 4 mA at 0
concentration to 20 mA at full scale.
(Full scale = 100% of programmable
range.)
6.8 mA = Range 1
12.0 mA = Range 2
16.8 mA = Range 3
