The instrument
range
may be selected by the hardware jumpers or by this software range setup.
To use the
software setup, you must remove all of the four hardware jumpers.
In the any fixed range, if the measured concentration is outside of the selected range or outside of the
display’s ability, the value will be shown in PPM oxygen, and the display will flash. Analog Output ranges
never extend.
