Pressing ENTER causes the
AUTO

MANUAL
after
'Span'
to start
flashing. Pressing UP or DOWN toggles the value. The value
determines the method by which the span settling period is complete and
a span calculation is automatically performed. If the value is
MANUAL
,
then when the span begins, the user is prompted to press ENTER at the
time he/she determines the sensor has settled on the span sample. If the
value is
AUTO
, the analyzer will automatically countdown the time when
the sensor has settled on the span sample, and will proceed to calculate
the new span slope, and return to
ANALYZE MODE
. The timer is now
fixed at 7 minutes. Note that the user may press ENTER to complete the
span even though the value is
AUTO
.
