To move the probe holders together
Figure 2-11 The slide bar assembly
1.
Ensure that the thumb-knobs, the lock screw, and the large knob are tight.
2.
Attach the probe holders to the slide assembly (see “To install the probe holder
onto the ChainSCANNER” on page 29).
3.
Rotate the large knob to adjust the position of the pair of probes (see Figure 2-11
on page 32).
In summary, the large red knob is used to move the two slide assemblies together,
while each small red knob moves its respective slide assembly. Once the distance
between the probes is set, you can then use the large red knob to maintain the probes
aligned with the weld during the displacement of the scanner. This is especially useful
on larger pipe diameters.
