After the Zero Count Filter has been installed it is very important to clean (purge) the system before reading the values to qualify
the system.
Purge system
Press “Purge Time” to define the initial wait time and the purge time.
“Initial wait time” means the time delay before the pump starts working. For example, you can use this time to leave a clean room
and let the laminar air flow re-establish itself before starting the sampling.
“Purge Time” is the time when the pump is already working, but the counting has not started yet. The pump needs a time of about
10 seconds to reach a stable operating condition. Therefore, the purge time should not be set below 10 seconds.
