Time/Date
Time
Here the time of day is set in the format hh:mm:ss.
Date Format
Display of date can be switched from European (DD.MM.YY) to American
(MM/DD/YY) notation.

rules, so it is not possible e.g. to enter the date 29.02.01. In order to make this test
possible, first the year, then the month and then the day has to be set.
Other Parameters

Set Active Channels
1Y 2Y 3Y 4Y 5N 6Y
In this example all channels except channel 5 are active.

completes one last zero cycle and then displays concentrations in 1 s intervals.
This is useful for finding ozone leaks by using a PTFE tube (with sample gas filter
attached) and "sniffing” in the area of an installation where a leak is suspected.
Channels can still be changed in Sniffer mode. A channel change will lead again to
one single zero cycle. Because the instrument will show a zero drift in this mode,
