The analog output signal has a voltage which depends on the oxygen
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.
To provide an indication of the range, a second pair of analog output
terminals are used. They generate a steady preset voltage (or current if you
have current outputs) to represent a particular range. The following table
gives the range ID output for each analysis range (Note: the 4 -20mA
Range ID output is a special option):
