For the purpose of this presentation, we will use
the .040 standard.

• Position the Testers selector switch to the
  .040 calibration.
• Turn the Tester ON.
• Set the Pass / Fail mark by using your thumb to
  align the red pointer flag with the ball.
• Now the red flag is set to equal a .040
  leak and it is calibrated for that vehicle.

At first the ball will go to the top of the flow
meter. The ball will slowly drop until it no
longer goes down. 3. Once the ball stops moving
downward, check the alignment with the red flag.
If the ball is below the red flag, the leak(s)
are less than .040 PASS If the ball is above
the red flag, the leak(s) are greater than .040
