Pumping capacity: The pumping capacity (patented method) can be adjusted in the
service menu between 20 and 100 %.
Remark: The adjusted pumping capacity has no effect on the suction height
but only on the average suction speed when extracting the sample.
The lower the pumping capacity, the longer the life of the pump!
