Using the Multitest
Torque Calibration System
The 2000-610-02 Indicator is designed to work specifically with
the MULTITEST series of smart transducers for measuring
torque. The MULTITEST series transducers contain a memory
chip that identifies the transducer range and calibration
parameters to the Indicator.
This chapter contains information on how to test, measure, and
use the MULTITEST Torque Calibration System.
Testing Torque Wrenches and Drivers
To use the MULTITEST 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.
