5.4.3. REPORTING RANGE MODES
The T801 provides three analog output range modes to choose from.
Single range (SNGL) mode sets a single maximum range for the analog
output. If single range is selected, all three outputs are slaved together and
will represent the same measurement span (e.g. 0-20 %); however, their
electronic signal levels may be configured for different ranges (e.g. 0-10
VDC vs. 0-.1 VDC).
Dual range (DUAL) allows the A1 and A2 outputs to be configured with
different measurement spans as well as separate electronic signal levels.
Auto range (AUTO) mode gives the analyzer the ability to output data via a
low range and high range. When this mode is selected the analyzer will
automatically switch between the two ranges dynamically as the
concentration value fluctuates.
Range status is also output via the external digital I/O status outputs (See Section
3.3.1.4).
To select the Analog Output Range Type press:
Upper span limit setting for the individual range modes are shared. Resetting the
span limit in one mode also resets the span limit for the corresponding range in
the other modes as follows:
SNGL DUAL AUTO
Range Range1 Low Range
Range2 High Range
