System Code
Info
The system code on delivery is 0000.
In this state, entry into the system is granted without having to enter the
system code. The system code protects the system from unauthorized use. Functions which may alter the
measurement of O
2
are therefore also protected.
Caution: If the system code has been altered, it must be kept in a safe place!

Adjustment of the Analyzer to the Dryer
The water vapor is not measured directly, but is calculated using the measured oxygen content. The water vapor
concentration is proportional to the quantity of the displaced oxygen. The water vapor is calculated using the
measurement of the O
2
concentration.
The O
2
reference value (dry), which is necessary for this evaluation, is different for each dryer and process.
Before commissioning, the system must be adjusted to the dryer, of which moisture content is to be measured. This
is carried out under:
SYS MENU -> System configuration -> H2O measuring range -> O2 reference value (dry).
