Figure 3-1. Visually divide the LCSF into four quad­rants as shown. The white arrows indicate the clamp pads in each quadrant.
1.
Turn the rotating ring to position the dial indicator tip at the clamp pad location in quadrant 1.
2.
Put the indicator tip against the inner surface of the pipe under the clamp pad.
3.
Set the indicator to 0 (zero).
4.
By hand, turn the rotating ring 180° so that the indica­tor tip is under the clamp pad in quadrant 3.
5.
The indicator dial will move into the plus or minus zone (unless the LSCF is perfectly centered across quadrant 1 and quadrant 3).

• If the dial moved into the plus zone in quadrant 3, then quadrant 3 has to move toward the
pipe by one-half the measurement indicated.
• If the dial moved into the minus zone in quadrant 3, then quadrant 3 has to move away
from the pipe by one-half the measurement indicated.
If the indicator has moved into the plus zone, loosen the clamp pad in quadrant 1 and tighten
the clamp pad in quadrant 3. Watch the dial as you adjust the screws; it should move about
half-way back to 0.
