Initial Operation
If you are unfamiliar with the M400E theory of operation, we recommend that you
read Section 10 before proceeding.
For information on navigating the analyzer’s software menus, see the menu trees
described in Appendix A.1.
3.2.1.
Start Up
After electrical and pneumatic connections are made, turn on the instrument power.
The exhaust fan and pump should start. The display should immediately display a
single horizontal dash at the far, left of the display.
This will last for
approximately 20 – 30 seconds
as the microprocessor loads its operating
system.
Once the CPU has completed this activity it will begin loading the analyzer firmware
and factory calibration data. During this process several progress messages, similar
to the following, will appear on the analyzer’s display.
The analyzer should automatically switch to
SAMPLE
mode after completing the
boot-up sequence and start monitoring O
3
gas. You should see the following
display.
The green SAMPLE LED on the front panel should be on, and the red FAULT LED
should be flashing, indicating a SYSTEM RESET fault. This is normal.
