Use the < > arrow keys to toggle between the span concentration value
and the units field (%/ppm). Use the
∆∆∆∆∆∇
arrow keys change the value and/or the
units, as necessary. When you have set the concentration of the span gas you are
using, press
Enter
to begin the Span calibration.

The beginning span value is shown in the upper left corner of the display.
As the span reading settles, the screen displays and updates information on
Slope
. Spanning automatically ends when the span output corresponds, within
tolerance, to the value of the span gas concentration. Then the instrument auto-
matically returns to the analyze mode.

Manual Mode Spanning
Press
Span
to start the
Span
function. The screen that appears allows
you to select whether the span calibration is to be performed automatically or
manually.
Select span
mode: MANUAL
Use the
∆∇
keys to toggle between
AUTO
and
MAN
span settling. Stop
when
MAN
appears, blinking, on the display. Press
Enter
to move to the next
screen.

<ENT> To begin span
Use the < > arrow keys to toggle between the span concentration value
and the units field (%/ppm). Use the
∆∆∆∆∆∇
arrow keys change the value and/or the
units, as necessary. When you have set the concentration of the span gas you are
using, press
Enter
to begin the Span calibration.
Press
Enter
to enter the span value into the system and begin the span
calibration.
Once the span has begun, the microprocessor samples the output at a
predetermined rate. It calculates the difference between successive samplings
and displays this difference as Slope on the screen. It takes several seconds for
the first Slope value to display. Slope indicates rate of change of the Span
reading. It is a sensitive indicator of stability.
