Otherwise inflate the bag to the maximum working pres- sure of 0.5 bar / 7.25 psi ± 10 %. At 0.55 bar / 8 psi the safety valve on the controller should be fully open, the pressure inside the bag may not rise any further. If the safety valve does not open fully, stop the test and remedy the fault in the manner explained under “Troubleshooting”. Once the fault has been remedi-ed repeat this part of the test.
