Measuring range switch-over and feedback signal
There are three ways of executing the measuring range switch-over:
• Manually on the gas analyzer
• Automatically (autorange) by means of appropriately configured
switch-over thresholds
• Externally controlled via appropriately configured digital inputs (see
page 82).
The measuring range feedback signal can be implemented via appropriately
configured digital outputs (see page 82); it is independent of the selected
type of measuring range switch-over.
The gas analyzer is set ex works to measuring range 2 and to manual meas-
uring range switch-over.
Measuring range configuration
The measuring ranges can be configured either in the configurator (see page
82) or in the gas analyzer (see page 84):
