(ie. When in 1/16 inch mode and three bars are showing, themeasurement displayed is rounded down to closest 1/16 inch and eachilluminated bar indicates an additional 1/64 of an inch (“heavy”)measurement.) For better resolution switch to 1/32 or 1/64 fraction mode.For the best resolution switch to a decimal mode.When the measurement is greater than + 99 63/64 inches, a +100 or +200will show in the upper right portion of the LCD to indicate this amount mustbe added to the displayed reading. ie: if the measurement is 154 5/8 inches,54 5/8 and +100 will be displayed on the LCD.
