responsibility column of the 43-180 on the USATA home page.
a. Verify that TI is clean and free from defects that would impair its operation.
b. Ensure that the equipment has been allowed to stabilize at the ambient
temperature.
c. Position torque plate on a stable and rigid work surface and secure with bolts or
clamps.
d. Assemble TI and torque cell no. 2 on torque plate using appropriate drive bar and
socket wrench adapter. Ensure that locating pins and drive bar are engaged in their
respective mounting holes. Install TI crank handle in socket as necessary.
e. Connect torque cell to force/torque indicator using cable supplied with force/torque
indicator. Connect force/torque indicator to appropriate power source. Turn power switch
to ON and allow the units to warm-up for 30 minutes. Select channel 3 using the
CHANNEL + and keys.
f. Press the F4 key on the force/torque indicator until the
