Updating the Catalytic Sensor Relative Response Setting
This menu item allows you to turn the catalytic sensor relative response feature on and off.
The catalytic sensor relative response feature enables you to change the catalytic sensor’s
response to gas on the fly so that the catalytic channel is roughly calibrated to an alternate
gas. For example, if the catalytic channel is setup for and calibrated to methane, you can
select hexane from a gas list accessible from the Catalytic Sensor Relative Response
Screen in Display Mode so that the catalytic channel responds to gas as if it were
calibrated to hexane. See “Catalytic Sensor Relative Response Screen” on page 44 for
instructions to use the relative response feature.
