Functional test
„
Observe the ambient and working conditions outlined in section 7 „Technical
data".
„
Please make sure that the pressure transmitter is only used within the over-
load threshold limit at all times!
The output signal must be proportional to the pressure. If not, this might point to a
damage of the diaphragm. In that case refer to chapter 10 „Troubleshooting“.
