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 when using the current outputs) to represent a particular range. Table 4-3 gives the range ID output for each analysis range.

Table 4-3: Range ID Output

Range	Voltage (V)	Current (mA)
Range 1	0.25	8
Range 2	0.50	12
Range 3	0.75	16
Range 4	1.00	20
