will display the different measurement modes. The measurement modes offered are metric circumference,
metric diameter, inch circumference, and inch diameter.
6) When not in use, the digital unit turns o automatically after approximately 5 minutes.
NOTE: If digital unit needs to be reset or error message is shown, turn o digital unit by pressing right button
until all characters disappear. Then repeat steps 2 through 4.
The diameter display has a resolution of 0.0005” (0.01mm) with an overall tape tolerance of ± .002” (± .06mm).
