Operation
It is recommended to read section 2.1 (Buttons) and section 2.2 (LEDs)
before continuing with this section.
5.1.
Startup
To turn the C12 instrument on, press button B1. All three LEDs are lit up
and will remain so for about 30 seconds during the startup sequence.
Normally, the startup procedure will be followed by the
Check
LED
flashing every other second (see section 2.2 LEDs). Now you have the
following options:
•
Enter monitoring mode as described in section 5.2.
•
Do a data server connection (see section 5.4.2).
•
Turn off the instrument (see section 5.5).
If the CompactFlash is missing, the initial startup time will be increased
by approximately another 30 seconds. After that, this state will be
indicated by the
Check
(red) and
Reg
(green) LEDs flashing
simultaneously.
Note! The instrument cannot be used without a CompactFlash inserted.
If the battery is almost empty the startup procedure will be aborted after
about 15 seconds, the
Check
LED (red) will be lit for approximately 5
seconds and then the instrument is turned off.
After an automatic instrument restart, when the C12 tries to start
monitoring, the
Reg
LED (green) will be fast flashing for 30 seconds
before entering monitoring mode. During this time, monitoring can be
aborted by pressing buttons B1 and B2 simultaneously for about three
seconds.
5.2.
Start Monitoring
To manually set the C12 instrument into monitoring mode, press the
buttons B1 and B2 simultaneously for three seconds. The
Reg
LED
(green) will flash fast to indicate the mode transition. After a few seconds
(depending on selected standard), the
Reg
LED changes to slow flashing
(once per two seconds). The instrument is now in monitoring mode.
