7.4.8 Analog Output Setup
Figure 54: Analog Output Setup Menu
The Zero Point corresponds to the lowest voltage or current output (0 VDC, 4 mA) that is 
sent to a recorder, while the Full Scale corresponds to the maximum voltage or current 
output (1/5/10 VDC or 20mA) that is sent.  The Full Scale set point (FS) is set from 0.002 
ppm to 20.00 ppm.
Three ranges can be entered in this screen.  The range of the primary Full Scale (FS) must 
be less than that of the Expanded Full Scale “A” (FS A) which must be less than that of the 
Expanded Full Scale “B” (FS B).  The analyzer auto-ranges between the three outputs 
depending on the current analyzer reading. Relay contacts can then be assigned to signal a 
change in range. If only one expanded range is required, rather than two, then the value of 
FS B should be set to equal the FS A value.
A window as narrow as 10% of the analyzer’s decades can be set for the full-scale analog 
output.
