Calibration

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 3/8-16 socket head cap

screws, each torqued to 45 ft lb. For additional information

refer to Figure 5-3.

Figure 5-3: 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.

Always position the 40" arm over the front of the

stand as shown. Never extend the test arm behind

the stand. The stand will tip over when weights are

applied.

The 40" test arm is coupled to the 2000-13-03, 1000 ft lb, and

2000-14-03, 2000 ft lb transducers using a 1-1/4" drive adaptor

plate.

1. Remove the internal drive adaptor plate and bottom plate

from the transducer using the torque wrench, ratchet

head and 3/8-3/8 hex bit or 3/4" open end adaptor

supplied.
