Installation instructions;
1. Determine proper setting distance using figures from Table 1 or the readings on the
calibration sheet. Using a hammer drill or other suitable equipment, drill two ½" holes
approximately 3" deep at the proper locations. Shorter holes may be drilled if the anchors
are cut down accordingly.
2. Assemble the Crackmeter with anchors attached. If installing the instrument at the mid-
range position, leave the nylon tie installed (see Figure 1) that secures the transducer shaft.
Fill the holes with grout or epoxy and push the anchors in until the tops are flush with the
surface. For holes drilled overhead use a quick setting grout or epoxy.
3. Secure the instrument after the grout or epoxy has set. Remove the cotter pins from the end
of each ball elbow joint and tighten the ball using a regular blade screwdriver. Re-install the
cotter pins to secure the ball locking screw. Remove the nylon tie.
4. Check the reading with a portable readout. Use Table 2 or the readings on the calibration
sheet to check the position. Installation complete.

Installation using Machine Bolt Expansion Anchors
The Bolt Expansion Anchor is needed to customize, applied to quick installation or unable to
install groutable anchor. The user self can also purchase inner expansion (inner explosion type)
bolt, make a M6 hole in bolt using for the connection of elbow joint.

Installation instructions;
1. Determine proper setting distance using figures from Table 1 or the readings on the
calibration sheet. Using a hammer drill or other suitable equipment, drill two ½" holes
approximately 2" deep at the proper locations.
2. Insert the expansion anchors with the threaded ends down into the hole, and tighten.
3. Remove the nylon tie securing the transducer shaft. Screw the ball stud on each end of the
crackmeter into the respective threaded holes in the anchors. Remove the cotter pins from
the end of each ball elbow joint and tighten the ball using a regular blade screwdriver. Re-
install the cotter pins to secure the ball locking screw.
4. Check the reading with a portable readout. Use Table 2 or the readings on the calibration
sheet to check the position. Installation completes.
