Observe all precautions in sections 4.4 and 4.4.2, above. Press
Span
to
enter the span function. The screen that appears allows you to select whether the
span calibration is to be performed automatically or manually. Use the
ΔΔΔΔΔ∇
arrow keys to toggle between
AUTO
and

span settling. Stop when
AUTO
appears, blinking, on the display.
Select span
mode: AUTO
Press
Enter
to move to the next screen.
Span Val: 2Ø.ØØ %
<ENT> To begin span
Use the < >
arrow keys to toggle between the span concentration value
and the units field (%/ppm). Use the
ΔΔΔΔΔ∇
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.
####.##% H2 — N2
Slope=#.### Span
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.
