Operation
The Model 3110XL is supplied completely assembled and ready
for use. The micro-fuel cell is supplied in a separate sealed bag, and in
the case of trace sensors, was purged with an inert gas.
Turning the instrument on by pressing the ENTER key will power
the display and show the power on screen briefly (if the display shows
nothing or is very dark, adjust the contrast). The display will then
change to indicate the oxygen concentration within the internal sample
passageways if no sample line is attached.
Note: To extend cell life and minimize the time required to make
the next analysis, the instrument should always be purged
with an oxygen free inert gas prior to being taken out of
service for standby or storage.
