Special Scaling for Concentra-
tion Signal
This menu allows for the setting of each
of the 8 outputs to be the same as the
range limit “Yes” or as set on the previous
menus.
See Section 3-5c, Ranges for setting the
range limits.
Pressing F5 (More…) changes to the
submenu Analog Output Updates per
Second.
Pressing the F5 (More…) key changes to
the submenu “Analog Output Updates per
Second.”
Analog Output Updates Per
Second
This menu allows for the setting of the
update rate for each of the 8 outputs.
c. Serial Interface Setup
From menu System SIO Module (Figure
3-25), select Serial interface setup…
In this menu, the parameters for data
transfer between the analyzer and exter-
nal devices are set. The choices in this
menu depend on the configuration of the
analyzer. The full specification of the se-
rial interface is described in its own man-
ual.
