NOTE: When testing tubes that have dirt or scale build-up, it may become necessary to replace or clean the � lter within the VLD unit.

Hold trigger and monitor gauge for approximately 10 seconds.

If the tube does not hold a vacuum, a drop in pressure will be detected on the gauge, indicating a leak in the tube.

Larger leaks will show more quickly than smaller ones.
