CHAPTER 4
SURETEST TORQUE CALIBRATION
SYSTEM SETUP
This chapter contains information on how to test, measure, and use the SURETEST
Torque Calibration System.
Testing Torque Wrenches and Drivers
To use the SURETEST Torque Calibration System for torque wrench testing, a
transducer of the appropriate range is fitted to the 2000-600-02 Manual Loader.
The Loader provides a stop that holds the torque wrench handle fixed and rotates the
transducer under the wrench drive. The system applies a precise, monitored torque to the
wrench. For additional information refer to Chapter 6—2000-600-02 Manual Loader.
Selecting a Transducer
When selecting a transducer, choose a single transducer that covers the low to high end
capacity of the torque wrench. Although possible, it is best not to change transducers
between calibration check points. For example: to test or calibrate a 20 to 100 ft lb
wrench, use the 2000-10-02 transducer, which covers the range between 10 and 125 ft lb.
Installing a Transducer
Install the transducer by lining up the red mark with the “TORQUE” label on the loader.
For additional information refer to 2000-600-02 Loader.
• Before changing or replacing transducers, adjust SET HIGH and SET LOW limits to
remain within the capacity of the tool under test. For additional information refer to
Chapter 3 Setting Up High and Low Limits Alert .
• If you must retain the statistical analysis, do not change SET HIGH and SET LOW
limits after changing the transducers and be careful not to exceed the wrench capacity.
The procedures provided are general. You may use or establish your own testing
procedures, techniques or standards.
