DET-HHD-STE-TA6-CM01

This procedure provides instructions for repairing power knobs that are too stiff to turn. If the instrument also has a display button that is too difficult to press, then the entire top housing should be replaced; refer to DET-HHD-STE-TA6-CM02, TA600 Top Housing Replacement. The 0.05-in. [inch] hex driver needed to perform this procedure is not a commonly available tool and should be obtained in advance of attempting this procedure. It is also recommended to use a magnifying glass as the components are very small.
