Functional test
Open pressure connections only after the system is without pressure!
Observe the ambient and working conditions outlined in section 8 „Technical
data.
Please make sure that the pressure transmitter is only used within the overload
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.
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“.
