 After the clamping of the piston/cylinder
system and the test specimen, air may be
trapped in the system.
 Afterwards, build the pressure back up.
 Attention: If the piston is not turning
easily or "squeaks", do not under any
circumstances force it to turn. Doing so
could cause lasting damage that would
seriously affect measurement properties.
 The piston/cylinder system must be
reconditioned by authorised specialists
