Cooper Instruments & Systems LTL 730 Wireless Tension Link Load Cell - Manual (Page 5)

CF 150 LTL 730 2 12/08
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 Instruments insists that a larger instrument be
used.
Safety is always a concern in overhead lifting and tensioning applications. To limit your liability always insist
upon factory supplied shackles and pins and factory tested and certified safe optional equipment. All COOPER
INSTRUMENTS products are designed to meet the published Safe Working Load (SWL) and Ultimate Safety
Factor (USF) standards of the United States Military.
Do not grind, stamp, drill or deform the metal on the dynamometer body in any way. Protect the instrument from
impact in use and storage.
Any significant damage or deformation to the loading element is cause for evaluation by Cooper Instruments,
particularly in the element side members to the right and left of the display.
Relieve all torsional and off axis loads.
Apply load in the center of the shackle bow with this instrument. Off center loading results in substandard
performance.
Instrument requires time to stabilize when changing temperatures.
Use only the hardware supplied with this instrument. If no hardware was supplied, insure that the mating pin and
shackle bow is equivalent to the hardware used at calibration. Otherwise substandard performance or failure
can result.
Cooper Instruments recommends only using qualified rigging hardware and cannot be responsible for
unapproved hardware.
This instrument is not designed for the following:
• Applications that see rapid, dramatic temperature swings or thermal shock. Wide variation in readings
can occur.
• Environments with high electromagnetic fields such as cranes employing electromagnets to lift metal.
These induce trace voltages that are picked up within the load cell lead wiring and appear as inaccurate
loads.
• Intrinsically safe environments. This unit has not been Factory Mutual tested.
2.1 Radio Safety
The radiated output power of this device is far below the FCC radio frequency exposure limits. Nevertheless, the
device shall be used in such manner that the potential for human contact during normal operation is minimized.
When connecting an external antenna to the device, the antenna shall be placed in such a manner to minimize
the potential for human contact during normal operation. In order to avoid the possibility of exceeding the FCC
radio frequency exposure limits, human proximity to the antenna shall not be less than 3 inch (7.5 cm) during
normal operation. The antenna is located at the connector panel on the Communicator.
2.2 Radio Communications Reliability
Low power radio systems should not be used in applications where timely updates of
readings are required for safety purposes.
