Instruction manual

ProCaliper

ProCaliper is easy to install and use. By following the installation

instructions in this section, reliable, error-free operation is assured, with

only an occasional need for adjustments or realignment of the jaws.

Assembly:

1. The jaws can be attached to the caliper in either of two positions.

They may be mounted on the upper or lower side of the lip on each

of the fixed or moving heads.

2. Loosely attach the left (fixed head) jaw to the caliper using the

supplied socket screws. Square the jaw to the caliper rail with a

machinist's square. Carefully tighten the screws, taking care to keep

the jaw square to the rail.

3. Loosely attach the right jaw (moving head) to the caliper using the

supplied socket screws. Slide the moving head up to the fixed head

until the measuring surfaces of the two jaws touch.

4. While holding the jaws together, carefully tighten the screws on the

moving jaw.

5. Using a feeler gauge, check for misalignment between the jaws near

the tip and the heel of the jaws. If a gap of more than 0.05mm

(0.002 inches) exists between the jaws at either point, loosen the

screws and repeat steps 2 through 4.

Mounting:

1. Determine an appropriate mounting surface for the ProCaliper.

Ideally, it should be mounted on an open, flat surface which does not

interfere with the moving head.

2. Notice the three 1/4-20 mounting holes in the bottom of ProCaliper.

Determine the depth of the mounting surface. Mount the rail to the

surface using bolts of the appropriate length, making certain it is
