Faraday Verification

The Faraday verification works only for hydrogen concentrations
below 40–50 ppb. If automatic Faraday verification is enabled, a
periodic check of the system is performed. A manual verification
can be started for test purposes.
Per default the instrument performs an automatic Faraday verifica-
tion every 3 hours. To change the settings for automatic verification
navigate to menu <Operation>/<Faraday Parameter>, see menu
4.1.3, p. 58 for details.
Possible settings are:
 off
 interval
 daily
 weekly
To start a manual verification:
1 Navigate to menu 3.2.2 <Maintenance>/<Service>/<Faraday
Verification>.
