Measuring range configuration in the gas analyzer
Menu Path
‘ Setup /  Measurement Ranges’
The measuring range parameters must be set individually for
each sample component.
Measuring range parameters
Figure 76: ‘Measuring range’ menu
Measuring range switchover mode
• Manual
• Automatic (Autorange)
• Externally controlled (DI control)
Measurement range limits
• Measuring range 1 initial value
• Measuring range 1 final value
• Measuring range 2 initial value
• Measuring range 2 final value
Autorange switchover thresholds
• Switchover from measuring range 1 to measuring range 2
• Switchover from measuring range 2 to measuring range 1
Note
• The automatic measuring range switchover (‘Autorange’) can
only be configured if an analog output is assigned to the
detector.
• The externally controlled measuring range switchover
(‘DI Control’) can only be configured if an analog output and a
digital input are assigned to the detector, see Figure 75 on
page 143.
• The values of the autorange switchover thresholds must
both be in the ‘Measuring range 2 initial value to measuring
range 1 end value’ range.
• The value of the autorange switching threshold MR2->MR1
must be less than the value of the switching threshold
MR1->MR2.
The conditions for the limits and combinations of the measuring
ranges must be observed, see Limits of measuring ranges on
page 141.
