Auto Range Switch Points determine when the analyzer automatically changes a
range up or down when the Auto Range function is turned on.
From the Range Setup
menu press
to access the Auto Range Switch Points screen.
The Default Switch Points
are created by the range limits. The Up Switch Point is 90%
of the Range Limit. The Down Switch Point is 90% of the previous range’s Up Switch
Point.
To change the Auto Range Switch Points, use the up/down arrows
to move
the highlight to the field you intend to change. Press
to open the field to change the
value in ppm. Press
again to close the field. Press
to save your changes. To
initiate the saved changes, press
, then press
and select new Auto Range Switch
Points.
In the example above, if the Range 1 concentration reaches 2.70 ppm, the analyzer will
switch to Range 2. If the concentration for Range 2 gets as low as 2.43 ppm, the analyzer
will switch to Range 1.
