- Page 4 The ’ ’ key confirms operations. It must be pressed each time a function is activated or to confirm a parameter. The ’ ’ key cancels current operations. This key can be used to interrupt a gas tight test or to reset the previous parameters.

- Page 6 An important point to bear in mind with regards the sequence of settings for a gas tight test is that the values inserted are saved and retrieved for carrying out the test only if the test itself is started. This stores the test data until a new test is carried out, but has the disadvantage that if a screen is cancelled by pressing ’...

- Page 8 The UNI 7129 norm test is required to approve new systems or reconditioned systems that have been unused for a period of maintenance. For the UNI 7129 gas tight test with PRESSOTEST prime the system to a pressure of at least 100mBar with inert gas, stabilise the test gas for at least 15 minutes and then wait 15 minutes while the instrument evaluates the fall in pressure in the system.
