5.5. Water monitoring
The analyser measures the water concentration of the sample gas in the
infrared measuring cell. A measurement of different sample gas compo-
nents is particularly accurate if the water concentration in the measuring
cell is as constant as possible and does not change after the zero point
has been taken. Reasons for a change can be a gradual drying out of the
gas cooler or subsequent components. The analyser offers with this menu
item the possibility to recommend or even start a new zeroing based on
the water measurement.
HINWEIS
The accuracies achieved in the proficiency test are real-
ised without this monitoring and derived zero point
taking. This monitoring is only intended for higher
accuracy requirements and is deactivated in the
delivery state.
•
You have the possibility to set a permitted deviation between
the reference value and the current value.
• You have the possibility to set an allowed duration of the
Deviation
• You have the possibility to set the time when the water monitor-
ing should start after the zero point has been taken.
