7.5.7 Moisture Analog Output Setup Routine
Figure 46: Moisture Analog Output Setup SubMenu
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 (1/2/5/10 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.
The In Calibration Relay can be enabled to signal that a zero calibration is in process. In
addition, the user has the option to freeze the analog output or enable the analog output to
update as the calibration progresses.
