Radio systems are vulnerable to interference, resulting in delays between the dynamometer scale and remote.
In some instances of interference, the display shown on the remote may be several seconds old. This can result
in a hazardous situation when the system is used as the reference for acceptable loads in cases such as proof
loading and monitoring of binding or overload. In these applications where timely updates are critical, a
communication cable should be used to physically connect the LTL 730 and Communicator remote (see setup
of RS-485 communications). Alternately, the LTL 730 display can be observed directly.
3.0 INTRODUCTION
The LTL 730 electronic dynamometer from Cooper Instruments is a force measurement load sensor and digital
readout in one instrument. The LTL 730 can be used to measure tension or weight. It can operate stand-alone
or be coupled with a remote Cooper Instruments Communicator, via radio communication or direct wire
connection, for improved convenience, functionality and safety.
This manual covers the setup and operation of the LTL 730 and optional Communicator.
This manual covers the following:
• LTL 730 & Communicator Description
• LTL 730 Setup
• Communicator
Setup
• LTL 730 & Communicator Operation
• Troubleshooting
Be sure to read the safety precautions found in the Safe Operation section.
If you overload this dynamometer you could suffer severe injuries or death. The
total load on the dynamometer should NEVER exceed the rated capacity!

LTL 730 Keys
There are four “hard” keys and four “soft” keys. The hard keys are permanently labeled and the soft keys are
just below the display. The soft key functions change and the key label appears above each key on the display.
Sometimes the individual soft keys are referred to as the F1, F2, F3 and F4 keys as numbered from left
to right.
If you press and hold the ZERO key for five seconds, the LTL 730 display will show the zero reference
calibration point.
