CALIBRATION CHAPTER 5
5-44
Torque Under 250 ft lb
Mount the calibration block at the center of the stand with two 1/2-13 socket head cap
screws with test bars that are 10" or shorter. Install these screws using the supplied torque
wrench and 3/8-3/8 socket driver adapter. Use this configuration for up to 250 ft lb of
applied torque. A 1/2" to 3/8" reducer is required when mounting the 10" arm to
transducers having 3/8" drives.
Torque Over 250 ft lb
For torque calibration above 250 ft lb, the calibration block is moved to the left for CCW
loading and to the right for CW loading. The torque arm is always extended over the front
of the reaction bracket for both CW and CCW torque applications. In this configuration,
useful up to 2000 ft lb, the calibration block is secured to the stand using four 1/2-13
socket head cap screws, each torqued to 75 ft lb. For additional information refer to
Figure 5-2.
Figure 5-2: Single High Torque Transducer Mounting Detail
The 2000-12-02, 600 ft lb transducer, requires the 1-1/4" to 3/4" drive reducer, supplied, to couple to
the 40" test bar.
