Analog output overrange example - INDIGO300

This example describes the analog output overrange behavior when an output uses a range of 0 ... 5 V, scaled to 0 ... 200 000 ppm (= 0 ... 20 %) CO₂. The error output level is set to 6 V, clipping limit is set to 5 % overrange, and error limit is set to 10 % overrange. CO₂ concentrations (ppm) are indicated for the clipping point and error limit point.

• When the measured CO₂ rises above 20 %, the output rises above 5 V.
• The output keeps rising until the measurement is 21 %CO₂, at which point the probe outputs 5.25 V.
• If the CO₂ level rises above 21 %CO₂, the output still remains at 5.25 V.
• If the CO₂ level rises above 22 %CO₂, the output enters the error state, which is 6 V for the 0 ... 5 V output.
