6.4.5. A1 & A2 Auto Range Mode
When the Auto Range mode is selected, the instrument reports the same data with
the same measurement span on both the A1 and A2 outputs, but automatically
switches both outputs back and forth between a user selected Low Range and a
user selected High Range depending on the level of the CO concentration. The unit
will move from Low Range to High Range when the CO
concentration exceeds to
98% of the Low Range span. The unit will return from High Range back to Low
Range once the CO
concentration falls below 75% of the Low Range span.
To set the ranges press following keystroke sequence:

The Low and High
Ranges have separate
slopes and offsets for
computing the carbon
monoxide concentration.
The two ranges must be
independently calibrated.

and
HIGH
range value.
