between two user-defined ranges (low and high). The unit will switch from low
range to high range when the CO
span. The unit will return from high range back to low range once both the CO
concentration falls below 75% of the low range span.
In AUTO Range mode the instrument reports the same data in the same range on
both the A1 and A2 outputs and automatically switches both outputs between
ranges as described above. Also, the RANGE test function displayed on the front
panel will automatically switch to show which range is in effect.
