After a test is started, move the grip probe about slowly at an average speed to
detect the leaking point. When a leaking point is located, the specific data will be
displayed on the screen and the buzzer will start beeping at a certain frequency.
Basically there are 5 levels: once every 5 second upon a value of 10% above the
alarm point; once every 3 second upon 50%; once every second upon 80%; and
once every 0.5 second upon 100%. The maximum testing time for each single
test is 4 minutes.

During a test, touch the ‘LED’ key on the panel users to turn on the white LED
light on the front end of the handle. This will help the user to detect a leaking

light.
3.9 During the process, if the“Measure” key on the handle trigger is touched, or the measuring
process has lasted for 4 minutes, the instrument will buzz and the measuring process will be
finished. Touch the “Measure” key on the handle trigger again to start another measuring
process.
3.10 When a measuring process is finished, the instrument panel will show the “Data Viewing
Interface”, which includes two pages, one for density data (Refer to Figure 9 below), and
the other for quantitative calculation (Refer to Figure 10 below). Touch “Up” or “Down” key
to view the pages:
