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

5.4.3.SETUP  RNGE  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 NO2 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.

5.4.3.1.SETUP  RNGE  MODE  SNGL: Configuring the 9110T Analyzer for Single Range Mode

Note Single Range is the default reporting range mode for the analyzer.

When the single range mode is selected (SNGL), all analog NOx, NO and NO2 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.

Although all three NOx outputs share the same concentration reporting range, the electronic signal ranges of the analog outputs may still be configured for different values (e.g. 0-5 VDC, 0-10 VDC, etc; see Section 5.9.3.1).

To select SNGL range mode and to set the upper limit of the range, press:
