Safe Operation

If you overload this dynamom-

eter you could suffer severe

injuries or death. The total load

on the dynamometer should

NEVER exceed the rated

capacity.

Keep all the following in mind as you use the EDjr dynamometer.

The system capacity is equal to the rating of the dynamometers. The

shackle rating should not be used to determine lift capacity of the system.

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, Dillon 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 DILLON prod-

ucts 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 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 Dillon, 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 can

result.

Dillon 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 employ-

ing 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.
