6.7. Faraday Verification
The Faraday verification works only for oxygen concentrations be-
low 200 ppb. If automatic Faraday verification is enabled, a periodic
check of the system is performed. A manual verification can be
started for test purposes.
Automatic
Verification
Per default the instrument performs an automatic faraday verifica-
tion every 3 hours. To change the settings for automatic verification
go to menu Faraday Parameter- Timer mode, see menu 4.1.3, p.
73 for details.
Possible settings are:
off
interval
daily
weekly
