NOTE: This is a Note symbol. Notes give additional and important information, hints
and tips that help you to use your product.
1.2 Installation
DANGER: RISK OF ELECTRICAL SHOCK. NO USER SERVICEABLE
PARTS. REFER TO QUALIFIED SERVICE PERSONNEL FOR SERVICE.
1.2.1 Safe handling of equipment with batteries
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer. Dispose
of used batteries according to the manufacturer’s instructions.
ATTENTION: Il y a danger d'explosion s'il y a remplacement incorrect de la
batterie, remplacer uniquement avec une batterie du même type ou d'un type
équivalent recommandé par le constructeur. Mettre au rebut les batteries
usagées conformément aux instructions du fabricant.
1.3 Safe Operation
Keep all the following in mind as you use the EDjr dynamometer.
DANGER: IF YOU OVERLOAD THIS DYNAMOMETER YOU COULD
SUFFER SEVERE INJURIES OR DEATH. THE TOTAL LOAD ON THE
DYNAMOMETER SHOULD NEVER EXCEED THE RATED CAPACITY.
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.
6 EDjunior Dynamometer User Instructions
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.
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:
l Applications that see rapid, dramatic temperature swings or thermal shock.
Wide variation in readings can occur.
l 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.
l Intrinsically safe environments. This unit has not been Factory Mutual
tested.

1.4 Routine maintenance
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.
1.5 Cleaning the machine
Table 1.1 Cleaning DOs and DON’Ts
DO DO NOT
Wipe down the outside of standard products
with a clean cloth, moistened with water and
a small amount of mild detergent
Spray the cloth when using a proprietary
cleaning fluid
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 instruction books.
To avoid the risk of RSI (Repetitive Strain Injury), place the machine on a surface which
is ergonomically satisfactory to the user. Take frequent breaks during prolonged usage.
1.7 Sharp objects
Do not use sharp objects such as screwdrivers or long fingernails to operate the keys.
Attempt to clean the inside of the machine
Use harsh abrasives, solvents, scouring cleaners or
alkaline cleaning solutions
Spray any liquid directly on to the display windows
