WHEN LOCATING THE BASE IN A FABRICATED PIPING SYSTEM CHECK
FOR ANY OBSTRUCTIONS, WELDS AND FLANGE-TO-PIPE MISALIGNMENTS
THAT COULD PREVENT THE BASE FROM LOCATING SECURELY.
5.2.3 Centralising the base within the bore
1. Locate the central mast onto the mounting base assembly. Secure with the cap
screws and use the dowels for location.
2. Slide the sighting bar into the pivoted bracket. Adjust the position of the sighting
bar to suit the flange diameter and clamp in position. Fit the knuckle bar,
knuckle and spike to the outer end of the sighting bar.
3. Using the spike select the datum diameter (i.e. raised face, 'V' groove or bolt
holes) and rotate the unit. Check the spike follows the datum and adjust if
necessary. To adjust the base, tighten and slacken opposite sets of ram bolts
(similar to a four jaw chuck operation) securing the unit progressively in the
flange until the desired accuracy has been achieved.

5. If a greater degree of accuracy is required, replace the spike with a Dial Test
Indicator (DTI) and proceed to Section 5.2.4.
