Functional test

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 9 „Troubleshooting".
Open pressure connections only after the system is without pressure!
„
Observe the ambient and working conditions outlined in section 7 „Technical
„
data".
Warning
Please make sure that the pressure transmitter is only used within the over-
„
load threshold limit at all times!
When touching the pressure transmitter, keep in mind that the surfaces of
the instrument components might get hot during operation.
