The analyzer is completely switched off.
The thermostatic control of the IR-cell is
switched on. The furnace is switched off
and the gas flow is disabled.
Communication with the PC is possible.
Furnace is switched on, but the gas flow
remains disabled.
All functions of the analyzer are in
operation mode.
In case the analyzer was switched off (pos. 0) for long, it should be set to pos. 1 for
at least 1 hour, in order for the IR-cell to reach the stable operating temperature.
The furnace heating-up time depends on the set temperature. In order to power the
furnace, the analyzer has to be switched to position 2. At this position the gas flow
is still disabled so that there is no gas consumption.
For running analyses set the power switch to position 3. At this position, the pump
is enabled so that air and any moisture which has entered the gas flow system can
be purged by the oxygen flow. Keep it there for about 10-15 minutes before starting
the first analysis. To save time, the purging can be started before the set
temperature has been reached. The slight influence of the oxygen flow on the
temperature of the infrared cell is compensated.
At short working breaks (like lunch breaks) the mains switch remains on position 2
(furnace on) to save gas and to keep the set temperature.
During longer breaks, e.g. after finishing the work for the day, the mains switch is
set to position 1 (standby). The thermostatic control of the infrared cell is then
working, so that no long warm-up time is needed, when re-starting the analyzer.
Energy consumption and wear are negligible on standby. The analyzer is designed
for long term use, so that no damage results.
Switch off the analyzer (position 0) is only useful, when working break takes
several days or weeks.
