Wobble is defined as the variation from the vertical of a rotating shaft or basket. The USP defines the maximum acceptable wobble as ±0.5mm.

The wobble meter is very simple to use. It uses a special vessel cover that fits inside the top of the vessel. This provides a static anchor point for the meter. (External devices offered by other companies tend to be hard to keep in position).

The wobble meter is firmly attached to this cover. The gauge is placed against the shaft or basket that is then rotated at a slow speed. Deviation from the vertical is displayed on the easy-to-read dial. The test is repeated in each vessel position.
