These keys are used to set the temperature, pressure, flow,
velocity, and other method operating parameters.
To display the current settings, press any one of these keys.
More than three lines of information may be available. Use
the scroll keys to view additional lines, if necessary.
To change settings, scroll to the line of interest, enter the
