Start-up
Before connecting the instrument to the mains, make sure that supply
voltage strictly corresponds to the requirements detailed in
Chapter
3.2.2
Before starting-up the instrument, remove dust seals from the
measuring gas inlets and outlets. Also check the existence of the
zero gas filter.
Now you may start the instrument by activating the mains switch on the
instrument front panel.

Operation
As soon as the instrument has been connected to the mains and switched-on,
it will automatically run through the following routines before starting the
actual measuring operation:
Self-Testing
Warm-up period
Auto-zero adjustment
During the startup-process the green power-light is flashing.
5.1 Self-testing of instrument
Immediately after the instrument is switched on, a self-test is performed.
All optic and acoustic displays are powered for a brief moment. The
compound to measure, its over-all measuring range and the software
release is shown in the LC-display.
During the warm-up period and also while in normal operation (except
while in Stand-By-Mode) the instrument will carry out automatic self-
testing at intervals of approx. 20 seconds as a check on important instru-
ment functions. In the event of any malfunction, the warm-up period or
the actual measurement cycle will be interrupted with the most probable
fault appearing on the display (see
Chapter 6,
- Malfunctions).
Simultaneously an acoustic as well as an optical alarm (flashing of
display and of fault indicator) will appear, which can be stopped either by
pressing the alarm-quit-button (if realized at the connected
machine/plant) or will stop automatically after 1 minute. In case of a
malfunction of the instrument, a restart of the instrument becomes
necessary.
