Operating Instructions Model 200E Instruction Manual
• Automatic range mode (AUTO) gives the analyzer the ability to report data through
a low range and high range by automatically switching into the appropriate range as
the concentrations change.
Only one of the above range modes can be active at any time. To select output range types,
use the following key sequences.
6.5.3. Single Range mode (SNGL)
The default range mode for the analyzer is single range, in which all analog concentration
outputs (usually A1, A2 and A3) are set to the same reporting range. This reporting range
can be set to any value between 100 ppb and 20000 ppb. However, the electronic signal
ranges of the analog outputs may still be configured for different values (e.g., 0-10 V and
0-0.1 V).
To select SNGLE range mode and to set the upper limit of the range, press:
SAMPLE RANGE = 500.0 PPB NOX=X.X

6.5.4. Independent Range Mode (IND)
The independent range mode allows the concentration outputs A1, A2 and A3 to be
configured with a different range value. In IND range mode the RANGE test function
displayed on the front panel will then be replaced by three separate functions:
• RANGE1: Range value for output A1 (NO

), e.g., 0-10 V for 0-1500 ppm NO

• RANGE2: Range value for output A2 (NO), e.g., 0-10 V for 0-1000 ppm NO.
• RANGE3: Range value for output A3 (NO
