3-3 STARTUP & INITIALIZATION
Establish sample or zero gas flow through the
analyzer module at a nominal flow rate of 2
SCFH (1 l/min). Allow gas to flow for 15 to 30
seconds before applying power. Apply power
to the TO2 Analyzer Module.
After switching on the TO2, the analyzer will
begin its booting procedure which is apparent
on the LCD screen. The first part of the
initialization procedure is a self check of the
software and analyzer components. Various
displays will show the status of the initializa-
tion including revision notes, “Initializing net-
work interface,” “Searching for nodes,”
“Querying Module: TO2, 12% Complete,” and
“Calculating bindings.”
Pressing the F1 key during initializing will re-
set the LCD brightness and contrast to factory
settings (See Section 3-4e). Pressing the F3
key will abort the network initializing, aborting
any connection to other analyzers. In that
case, only the menus of the local analyzer will
be available.
At the end of the initializing routine the
“measure” screen will display as shown on the
next page. This screen is the access to all
other channels, menus and submenus. The
actual display may differ from that shown de-
pending on any custom configuration as de-
scribed in Section 3-5e.
