The display limits for the different units of measurement are summarized in the table
below.
The lower display limit may be increased by the user. Please refer to Section 4.5.3
for how to edit the lower display limit.
As soon as an acoustic alarm sounds, the tip should be removed from the spot being
tested. After displaying a constant leak rate the ZERO button should be pressed
again to repeat the test. Thus, a measurement error can be prevented and the leak
can be located.
