Output Signal = 0 – 5 VDC representing 0-500 ppb concentration
values.
The user may also add a signal offset independently to each output (see Section 5.9.3.9)
to match the electronic input requirements of the recorder or data logger to which the
output is connected.

The instrument does not remember upper range limits settings associated with
the individual modes. Changes made to the range limits (e.g. 400 ppb

600 ppb)
when in one particular mode will alter the range limit settings for the other
modes.
When switching between reporting range modes, ALWAYS check and reset the
upper range limits for the new mode selection..
5.4.2.2. ANALOG OUTPUT REPORTING RANGE DEFAULT SETTINGS
The default setting for these the reporting ranges of the analog output channels A1, A2
and A3 are:

SNGL mode

0 to 500.0 ppb

0 to 5 VDC

MODE
Single range mode (SNGL) reports all three of the NOx gas concentrations using the
same reporting range span (see Section 5.4.3.1).
Independent range mode (IND) allows the NOx, NO and NO
2
analog outputs to be set
with different reporting range spans (see Section 5.4.3.2).
Automatic range mode (AUTO) allows the analyzer to automatically switch the
reporting range between two user upper span limits (designated LOW and HIGH) based
on the actual concentrations being measured for each (see Section 5.4.3.3). These are not
the same as the analyzer‟s low and high physical ranges (Section 5.4.1).

Note Single Range is the default reporting range mode for the analyzer.
When the single range mode is selected ( SNGL ), all analog NO

concentration outputs ( A1, A2 and A3 ) are slaved together and set to the same reporting
range limits (e.g. 500.0 ppb). This reporting range can be set to any value between 100
ppb and 20,000 ppb.
