O Cell
This measuring cell is designed for operation within the measuring limits of 0
inH
2
O (absolute) to 100 inH
2
O (absolute). When stored in the normal ambient
pressure of about of about 14.7 psi (absolute), the measuring cell is in the
overload state. An overload error of up to 0.8 inH
2
O may occur. The overload
disappears in normal operation within the measuring limits and the transmitter
operates within specifications.
When performing accurate continuous pressure measurements within the
measuring limits, a readjustment of the transmitter zero for absolute pressure
must be performed after approximately one day (refer to Section 6.2.5).
