Analog Output Tab
The
Analog Output port has a 16-bit voltage range from 0 to 5 volts.
The user can specify a conversion between gas concentration and the analog output
voltage, using the spinner controls, or by manually typing a number into the field. (Figure
38) The dropdown spinner controls let you select the concentration value that will
correspond to the maximum 5 VDC analog output.
For example:

Set 5 Volts = 10 ppm on the expectation that the gases measured will be in the
range near 2 ppm, with occasional bursts up to almost 10 ppm.

Set 5 Volts = 5 ppm to get exactly two times greater sensitivity on the analog
output, with the expectation that the concentration will not go above 5 ppm.
If the measured concentration goes above the maximum expected value
for the Analog Output, the on-screen displays and data files continue to
record the correct measured concentration, but the Analog Output will
saturate at its maximum value of 5.0 volts until the concentration drops
back into the expected range.
