Always ensure the red clamp is attached to the positive battery post and
the black clamp is attached to the negative battery post.
Flow Meter: A small floating ball indicates when air is flowing. The ball indicates a
positive air flow if there is a leak internally to ELF-1 during initial setup or
in the external system during a leak test.

3 PSI mode. Turns off when 1 or 3 PSI is attained. It will illuminate
continuously when in the 4-15 PSI mode.
