6.5 System setup with several analyzers in parallel
The analyzer must have been in operation for at least 30 minutes before commencing with
measurements since a good stability of the analyzer unit is only guaranteed after this time
(99% value).
Make sure that the gas flow is between 1.2 and 2.0 l/min.
Any noise which may occur can be suppressed by adjusting various time constants (see
Parameters: Time constants (Page 129)).
The calibration should be repeated every six to twelve months depending on the ambient
conditions.

System setup with several analyzers in parallel
Example 1
Both analyzers with internal pump and solenoid valve switching between sample gas and
zero gas for AUTOCAL
The cyclic AUTOCAL of the master device triggers an AUTOCAL in parallel for the slave
device via its digital output SYNC and the digital input SYNC of the slave device.
The simultaneous connection between the digital output SYNC of the slave device and the
digital input SYNC of the master device guarantees that zero gas is always passed
simultaneously through both analyzers.
