Screwing together the measuring cell results in significant overpressure in the lower half of the cell.
This overpressure decreases quickly because the solvent permeates through the pores of the semi-
permeable membrane. The screwing together is performed manually without tools.
The overpressure created during this operation can easily destroy the sensitive pressure transducer.
Therefore, the measuring cell has to be screwed together carefully in small intervals.
If the pressure increases to above 99.9 cm water column, the display starts flashing
(Figure 4-12)
. If
the pressure increases further to approx. 550 cm water column, the "overload" warning light comes on
(Figure 4-13)
. When an alarm sounds, you must immediately stop the screwing operation, otherwise
the pressure transducer will be destroyed. You may resume after the pressure has decreased enough
so that the "overload" LED goes off.
The measuring cell is screwed together in small increments until the end stop is reached by firmly
turning by hand.
