Fluke 831 - Asymmetric and Symmetric Tolerances; Tolerance Table Based on Coupling Format

Use the onscreen keyboard (4) that comes into view. The edited values are shown (5).
Asymmetric and symmetric tolerances
When asymmetric tolerances have not been enabled (1), the displayed specified tolerances
(2) are symmetric. The gap and offset tolerances for both horizontal and vertical planes are
identical.
If asymmetric tolerances are enabled (3) all four specified values are displayed (4).
Tolerance table based on coupling format
For the same type of tolerance, RPM, and coupling diameter, the tolerances value differ with
the coupling format selected. To select the necessary coupling format, tap the item "Coupling
format" in the tolerances screen.
