2.3.3.1 Analog Outputs
There are four DC output signal pins—two pins per output. For polar-
ity, see Figure 2-3. The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing concentration,
from 0 V at 0 concentration to 1 V at full scale.
(Full scale = 100% of programmable range.)
0–1 V dc Range ID: 0.25 V = Range 1, 0.5 V = Range 2, 0.75 V =
Range 3, 1 V = Cal Range.
4–20 mA dc % Range: Current rises linearly with concentration, from 4
mA at 0 concentration to 20 mA at full scale. (Full
scale = 100% of programmable range.)
4–20 mA dc Range ID: 8 mA = Range 1, 12 mA = Range 2, 16 mA =
Range 3, 20 mA = Range 4.
