and page numbers appear at the bottom of the pages.
1.1.1 Text conventions
Key names are shown in bold and reflect the case of the key being described. If a key
has a dual function it may be referred to by its alternate function.
Displayed messages appear in bold italic type and reflect the case of the displayed
message.
Annunciator names appear as italic text and reflect the case of the annunciator.
1.2 Special messages
Examples of special messages you will see in this manual are defined below. The
signal words have specific meanings to alert you to additional information or the relative
level of hazard.
WARNING! This is a Warning symbol. Warnings mean that failure to follow
specific practices and procedures may have major consequences such as
injury or death.
CAUTION! This is a Caution symbol. Cautions give information about

General information and warnings
1.3 Safe operation
Keep all the following in mind as you use the 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.
The shackles are rated in metric tonnes. Thus the 12-tonne shackles are rated to
26,450 lbf and are suitable for use on the 25,000 lbf dynamometer.
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 products are designed to meet the
published Safe Working Load (SWL) and Ultimate Safety Factor (USF) standards of the
United States Military. All CE marked models meet the SWL and ULL (Ultimate Load
Limit) requirements of the European Machinery Directive.
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 Dillon.
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.
Dillon recommends only using qualified rigging hardware and cannot be responsible for
unapproved hardware.
This instrument is not designed for the following:
lApplications that see rapid, dramatic temperature swings or thermal shock.
Wide variation in readings can occur.
lIntrinsically safe environments. This unit has not been Factory Mutual or
ATEX tested.
WARNING: If you overload this dynamometer you could suffer severe injuries
or death. The total load on the dynamometer should NEVER exceed the rated
capacity.

1.5 1.5 Cleaning the Dynamometer
Cleaning DOs and DON’Ts
lDO - Wipe down the outside of standard products with a clean cloth,
moistened with water and a small amount of mild detergent
lDO NOT - Attempt to clean the inside of the machine
lDO NOT - Use harsh abrasives, solvents, scouring cleaners or alkaline
cleaning solutions
1.6 Training
Do not attempt to operate or complete any procedure on a machine unless you have
received the appropriate training or read the instructions.
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.

2.1 General description
A dynamometer is an instrument that displays the tension force exerted between the
two attached shackles. It is generally used to determine tension in a line/cable or for
suspended weighing.
Figure 2.1 shows one model of dynamometer.

CAUTION: Dillon Dynamometers are not designed for measurement of dynamic
shock loads and should not be subjected to sudden force. Load or weight
should be applied in a gradual manner to avoid damaging the Dynamometer.
Torque loads applied to the dynamometer should be relieved or avoided.
Dynamometer Installation Instructions 9
2.1 General description
Heavy duty needle bearings inserted in each end of the Dynamometer deflection beam
(or into both sides of the shackles ears) allow the shackle pin to rotate as force is
applied. See Figure 2.1. Bearings should be cleaned periodically in a suitable solvent.
After drying, the bearings should be treated with a coat of light machine oil (SAE-5W
non-detergent oil or lighter).
The case is not water-tight and if the Dynamometer should be accidentally immersed,
hold it so that water is free to run out through the openings in the bottom of the case
and allow to dry.
CAUTION: DO NOT allow oil to run into the mechanism case. The mechanism should
never be oiled as this tends to attract dust or dirt.

Introduction
2.2 Third-party shackles and attachments
Dillon supplies shackles and pins with the dynamometers that have been confirmed to
properly work with our mechanical dynamometers. Do not use shackles or shackle pins
that have not been qualified by Dillon. Lower profile non-machined spots can often be
observed and are normal.
If any type of accessory fitting is made for use with the Dillon Dynamometer, be sure to
machine this from high grade aircraft alloy (E4340 steel or equivalent) and heat treat it
in order to ensure maximum safety.
2.3 Maintenance and handling
The Dillon Dynamometer is a precision instrument and will provide many years of
dependable service if given reasonable care and suitable protection. Many firms make
it a regular practice to return Dynamometers to their distributors at 6 to 8 month
intervals (depending upon how much they are used) to have accuracy recertified. We
recommend this at least once a year. Consult with your Dillon distributor concerning
any questions you may have about recalibration intervals. Your area may require
periodic proof testing. Consult your local regulations.
Transport and store the dynamometer in the supplied storage case when not in use.
Dillon / Avery Weigh-Tronix is not responsible for failure of attachment fittings
furnished by others.

3Operation
Zero the dynamometer for best accuracy. To properly zero the instrument when using
the max pointer, adjust the black needle below the desired zero point using the zero
adjustment wheel on the rear of the case. Move the red maximum pointer
counterclockwise until it contacts the black needle. Use the zero adjustment wheel to
simultaneously move both pointers to the desired zero point. This procedure will
prevent the slight drag of the max pointer from influencing the displayed reading. If the
max pointer is not required, rotate the red pointer clockwise until it reaches the zero
position and operate normally.
Dillon Mechanical Dynamometers permit zeroing of up to 20% of instrument capacity.
Do not zero off a deadload and then use the instrument to capacity.
WARNING: Failure to adjust the max hand prior to use of the Dynamometer
WILL affect the readings if the max hand is used.
