CO SPAN RATIO
A microprocessor-generated field that is the value by which the span reading is
multiplied to correct the reading to the calibration value. This value is only
applied if SPAN COMP is ENABLED.
BACKGROUND
A choice of START, DISABLED or ENABLED. If START is selected, then when
<Enter> is pressed the instrument begins an auto-zero (background) cycle. If
DISABLED is selected, then the instrument will not run the normal auto-zero
(background) cycle. If ENABLED is selected, then the instrument will run the
normal auto-zero (background) cycle.
Note
The background cycle must not be disabled for U.S.
EPA designated use.
BACK. INTERVAL
Set time in HOURS (2, 4, 6, 8, 12, 24). A microprocessor-controlled
field that indicates when an autozero cycle will begin. The results of the
background are stored in the EVENT LOG.
