Trace Oxygen Analyzer
3.3.3 Analog Outputs
There are eight DC output signal connectors on the ANALOG
OUTPUTS connector block. There are two connectors per output with
the polarity noted. See Figure 3-5.

The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing oxygen,
0–1 V dc Range ID:
4–20 mA dc % Range: Current increases linearly with increasing
4–20 mA dc Range ID: 8 mA = Low Range

from 0 V at 0 ppm to 1 V at full scale ppm.
(Full scale = 100% of programmable range.)
0.25 V = Low Range
0.5 V = Medium Range
0.75 V = High Range
1 V = Air Cal Range
