2 Installation Model 6600

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.

Table 2-1: Analog Concentration Output-Examples

Concentration	Voltage Signal	Current Signal
%	Output (V dc)	Output (mA dc)
0	0.0	4.0
1	0.1	5.6
2	0.2	7.2
3	0.3	8.8
4	0.4	10.4
5	0.5	12.0
6	0.6	13.6
7	0.7	15.2
8	0.8	16.8
9	0.9	18.4
10	1.0	20.0

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.
