Versatile
The Model
920 instrument is designed to conduct torque testing before, during
or after assembly. Although it fits comfortably in the hand, the 920
is powerful and accurate enough to be used as a primary standard for
auditing most torque applications in manufacturing and quality departments.
You can use it to test the capability of power tools, verify the accuracy
of hand tools, monitor the capability of a fastening process, or audit
the quality of an assembled joint. The 920 can also be easily set up
for use with force washers, clamp force sensors, and other transducers
to measure fastener assembly preload, press force, pressure, and many
other applications.

Easy to
Use
The Model 920 can
measure and record data quickly, easily, and accurately. It reads the
ID chip in most RS Technologies transducers to speed setup and calibration.
The alphanumeric display is easy to read and prompts you through setup
and operation as needed. The 920 displays peak and track data simultaneously
and measures in either the clockwise or counterclockwise (compression
or tension) direction. It contains an on-board library of transducer
setup data to simplify tool selection. Pick from one of five user-defined
transducer setups or from the library of RS Tech transducers.

Quick Data
Outputs
The built-in serial port lets you
print data and statistics right from the Model 920.
The recorded data can also be easily uploaded to a personal computer
for further analysis using the HyperTerminal application provided with
the Windows operating system.
