Input purge cycle
To guarantee that the sample being analyzed is current, the sampling
line must be sufficiently purged over its entire length. When the sys-
tem is unused for an extended period and when the analysis interval
is considerable, a purge cycle of more than 60 seconds should be
selected. The purging is performed by simultaneously opening the
inlet and outlet valves of the Testomat® EVO TH.
Duration of the analysis interval
The analysis interval depends directly on the programmed purge
cycle. If for example a purge cycle of 90 seconds is set, the analysis
interval must be at least 90 seconds as well.
Internally enter the purge cycle
Select in the menu
Basic program => Flush time => Time
Input in the menu option "Time" the time in seconds(s).
(The factory default setting is 00 seconds(s))
Confirm all entries with "OK"
Enter excess
An additional purge cycle can be entered here after the limit value
has been exceeded, if the internal purging is not sufficient to flush out
the intake. The internal purge cycle is then extended by the set time.
Input the time in minutes (m) and seconds (s) in the menu option
"ExceedanceFlush".
(The factory default setting is 00m:00s )
Confirm all entries with "OK"
Select water meter
For quantity-based analytical trigger, a water meter must be connect-
ed to the WM input (WM = water meter).
