5. Insert the anti-rotation pin into one of the holes on the bottom of the crosshead.
There are four pin holes on the bottom of the crosshead that let you position the load
cell either straight on or at an angle.
6. Place the locating ring into the top surface of the load cell that connects to the cross-
head.
7. Place the load cell against the bottom of the crosshead, ensuring that the anti-rota-
tion pin and locating ring fit securely in place against both the crosshead and load
cell. Place the cable to the left side of the column.
8. Tighten the mounting screw by hand so that it secures to the load cell underneath the
crosshead.
When applying torque to the mounting screw, prevent the load frame from sliding by
holding the crosshead with one hand while applying torque with the other.
9. Use the torque wrench to tighten the mounting screw to 25 N-m (18.4 ft-lb).
10. Connect the load cell cable to the
FORCE connector on the controller. Ensure that the
connector is fully engaged in the socket.
11. Press the load cell cable into the clips on the column cover to prevent it from inter-
fering with your test.
12. Calibrate the load cell (refer to “Calibrate a transducer” on page 99).
13. Leave the system on for at least 15 minutes to allow the load cell circuitry to stabilize.
After this warm-up period, calibrate the load cell again.
Adapters
Adapters let you connect grips or fixtures to the frame when the interfaces have
different connection sizes. There are two types of adapters: base adapters and coupling
adapters.
Base adapters
Base adapters let you connect grips and fixtures to the base of the load frame. The load
frame is are supplied with a Type O base adapter installed. A Type D base adapter is
supplied in the ancillary parts kit. If you need to remove and re-install the base adapter,
for example to change the orientation, use the following procedures.
