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. Press the key to select the component you wish to view or change.
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 90.00 ppm, the analyzer will
switch to Range 2. If the concentration for Range 2 gets as low as 81 ppm, the analyzer
will switch to Range 1.
