2.5 Zero
Press when the Dyna-Clamp is not under tension to remove small deviations of the zero reading. Zero on location, just
prior to positioning the Dyna-Clamp on the wire rope. Re-zero the Dyna-Clamp each time the wire rope selection is changed.
The Dyna-Clamp must be held horizontally by the carrying handle. The load cell mount assembly must be fully
suspended and not in contact with any surrounding surfaces or objects before pressing
. The unloaded
indication on the display will vary slightly depending on orientation. This variation is negated once under tension.
2.6 Tension Measurement
The following procedure describes how to connect the Dyna-Clamp to a wire rope to take a tension reading. The Dyna-Clamp
can be used to monitor the tension of a wire rope for maintenance and installation applications.
Always ensure that the wire rope is centered on both bobbins and never use the Dyna-Clamp on a wire rope
diameter over 1''. Regularly apply moly grease to the drive rod threads to maintain proper lubrication.
1. Loosen the drive rod.
2. Zero the Dyna-Clamp (
Section 2.5 ).
Figure 2-2. Dyna-Clamp On Wire Rope
3. Position the Dyna-Clamp on the wire rope ( Figure 2-2 ).
Position Dyna-Clamp directly to the wire rope, at least two feet from any attachments or the termination points.
4. Roll the Dyna-Clamp 6-8'' back and forth along the wire rope to align the unit to the center of the wire rope.
5. Tighten the drive rod assembly firmly, torquing the drive rod to approximately 60-100 in-lb. The optimal torque rating
varies depending on the wire rope diameter and construction.
Do not over tighten the drive rod. Over tightening could cause damage to the wire rope or the Dyna-Clamp.
6. Take the tension reading from display. See Section 2.7 on page 5 for how to use the Average Function.
7. Loosen the drive rod assembly and remove the Dyna-Clamp from the wire rope.
8. Repeat
Steps 3-7 to take additional tension measurements as needed. For the best accuracy take at least three
tension readings at slightly different locations along the wire rope using the Average Function ( Section 2.7 on page 5 ).
