Chapter: Installation
34 M10-14052-EN
Equipment
You need the following items:
• a specimen capable of withstanding a tensile load equal to the current load string
preload
• spanner wrench (1/4 in.)
Checklist
Check for the following conditions before you preload the grips:
• The jaw faces are installed.
• The side plates are secure. If you are using a 50 kN wedge grip, ensure that either
the spacers or side plates are fitted on the grip and are secure.
• If using a 50 kN grip, check the thickness of your specimen and ensure that the
appropriate spacers or side plates are installed. Refer to “Installing the Spacers
and Side Plates” on page 29 for additional information.
• The Load channel indicates a zero load.
• The electronic load limits are set to protect the weakest load string component.
Procedure
1. Install a specimen. Refer to section “Installing a specimen” on page 35.
2. Set the control electronics for a tensile load equal to the amount of the current load
string preload.
3. Using the spanner wrench, turn each locknut away from the mounting device (load
cell, baseplate clevis, or actuator).
4. Repeat Step 1 through Step 3 for the other grip.
5. Refer to section “Removing a Specimen” on page 37 to remove the specimen.
