Teledyne Analytical Instruments
The analog output signal has a voltage which depends on the sample
concentration AND the currently activated analysis range. To relate the
signal output to the actual concentration, it is necessary to know what range
the instrument is currently on, especially when the analyzer is in the
autoranging mode.
The signaloutput for concentration is linear over currently selected
analysis range. For example, if the analyzer is set on a range that was
defined as 0-10 %, then the output would be as shown in Table 2-1.

To provide an indication of the range, a second pair of analog output
terminals are used. They generate a steady preset voltage (or current when
using the current outputs) to represent a particular range. Table 2-2 gives the
range ID output for each analysis range.
