Functional Test - WIKA WUD-20 Betriebsanleitung

7. Initial start-up and operation

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 10 „Trouble shooting".
WARNING!
Open pressure connections only after the system is without pressure!
■
Observe the ambient and working conditions outlined in chapter 7 "Initial start-up and operation".
■
Please make sure that the pressure transducer is only used within the over load threshold limit at all times!
