Restarting the Gas Analyzer
NOTE
New and still unused sample gas lines and sampling probes can release
hydrocarbons over a longer period after initial start-up. Therefore, it can
take a longer time until the measured value drift has reached an
acceptable value.
1 Feed in instrument air and combustion air and purge the gas analyzer
for at least 20 minutes.
2 Switch on power supply of the gas analyzer.
3 Turn on the combustion gas supply and adjust the combustion gas
pressure.
4 Check (see page 118) the seal integrity of the combustion gas feed
path.
5 Turn on the sample gas supply.
ATTENTION
The connection cable of the 115/230 V AC power supply for heating
the detector and possibly the heated sample gas connection may not
be removed under voltage on any account!
The cover of the heated sample gas terminal is hot during operation. It
reaches a temperature of more than 70 °C!
