3.2. Extension Arms
Fig. 7: Tighten thumb screw
- Align the receiving component’s hole (centre base, blind side base, arms) with the thumb screw (Fig. 7) of the connecting component.
- Ensure correct arm orientation when using magnetic arms.
- Place magnetic arms furthest from indicator for optimal stability.
- A small radius on the bottom surface assists with measuring along the length of small diameter pipes.
3.3. Indicator Adjustments
Fig. 8: Loosen to pivot indicator Fig. 9: Centre base or blind side base
Fig. 10: Rotate indicator face
- Loosen the thumb screw to pivot the indicator when required (Fig. 8).
- Loosen thumb screw to switch indicator for use with either base (Fig. 9).
- Rotate the indicator face during inverted scanning (Fig. 10).
3.4. Optional Magnetic Arm (Fig. 11)
Fig. 11: Adjust magnetic attraction with lever
- The red lever controls the amount of magnetic attraction.
- Pivot the lever left to disengage all magnetism, pivot the lever to the right to engage full magnetism.
3.5. Blind Side Base (Fig. 12)
Fig. 12: Blind side base
- Use to measure when centre base is not appropriate (i.e. close to a weld or flange).
