Check your user manual on the CD for further detail on obtaining best accuracy.
Î Please note... IMPORTANT: This equipment must be routinely checked for proper operation and calibration. Application
and usage will determine the frequency of calibration required for safe operation.
Safe Operation
Any zeroed deadload must be considered as part of the ultimate load.
Although this instrument has a substantial overload protection rating, the instrument should not be used above the rated
capacity. Doing so can significantly impact fatigue life of the instrument and cause premature and abrupt failure. If a higher
capacity reading is needed, Cooper insists that a larger instrument be used.
Do not grind, stamp or deform the metal on the dynamometer body in any way.
Any significant damage or deformation to the loading element is cause for evaluation by Cooper, particularly in the element
side members to the right and left of the display.
Always observe all safety code standards and ratings when lifting or in hazardous environments.
Insure all hardware, fittings and line used to sustain the load are properly sized and rated for the application. Have
the system evaluated by a qualified engineer if any question or uncertainty exists.
Check your user manual on the CD for further detail on obtaining best accuracy.
Radio Information
The radio technology used in the radio equipped LTL and Communicator is a 2.4 GHz digital spread spectrum system
designed for communications reliability.
Tips for best performance:
• Keep the Communicator and LTL as close as possible together.
• Keep metal and other dense objects as far from the instruments as possible.
• Normally the higher that both the LTL and Communicator are above the ground, the better the performance and
range will be.
Check your user manual on the CD for further detail on communications.
Radio systems are vulnerable to interference, resulting in delays between the dynamometer scale and remote. In some
instances 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 or monitoring of overload. When timely
updates are critical, a communication cable should be used to physically connect the LTL and Communicator. Alternately,
the LTL display can be observed directly
Î Please note... WARNING! Low power radio systems should not be used in applications where timely updates of
readings are required for safety purposes.
Annunciators
Force This tells you that the display is showing live force measurement at the moment. Will show
Peak when viewing Peak Mode.
lbf Current unit of measure is lbf in this example. May also be kgf or N.
~ Motion symbol. This appears when the force is in motion. This symbol disappears when
motion ceases.
(Y) The is configured ON and is in communication with a Communicator
Y The radio is configured ON but is not in communications with any Communicator.
The radio is configured ON but is not in communications with any Communicator. The battery
in the device is too low to power the radio electronics. The LTL will continue to display but not
communicate by radio.
Battery annunciator. This shows approximate remaining battery life.
