Introduction
The EDjuniorTM (EDjr) electronic dynamometer from Dillon is a force mea-
surement load sensor and digital readout in one instrument. The EDjr can be
used to measure tension or weight.
This manual covers the setup and operation of the EDjr. General information
is covered in the right column of each page with major sections separated
by the black bar shown above. Subheads appear in the left column along
with any special notes, cautions or warnings.
This manual covers the following:
• EDjr Description
• EDjr Setup
• EDjr Operation
• Troubleshooting
Be sure to read the safety precautions found in the Safe Operation section.
The EDjr comes in several weight capacities. All have the same front panel,
shown in Figure 1.

EDjunior front panel
There are four “hard” keys and four “soft” keys. The hard keys are perma-
nently labeled and the soft keys are just below the display. The soft key
functions change and the key label appears above each key on the display.
Sometimes the individual soft keys are referred to as the F1, F2, F3 and
F4 keys as numbered from left to right.

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.

On/Off key Use this key to turn the unit on and off.
ZERO key Use this key to zero the force indicated
on the display.
ESC key Use this key to escape from portions of
the menu structure and return to previ-
ous choices or displays.
Arrow key Use this key to access any available soft
keys not currently viewed.
If lift hardware (shackles,
chains, beams, hoppers, etc.)
is used to support the load and
zeroed prior to lifting the
current load being displayed,
you can press the ZERO key
for five seconds, the display
will show the total load being
lifted based on the zero point
used in calibrating the EDjr.

Power On and Annunciators
When you power up the EDjr you will see a display similar to the example
shown on the left in Figure 2.
Figure 2
Initial displays
The display sample above shows several symbols you may see on your
display but usually not all at the same time.
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.
Battery annunciator. This shows approximate remaining battery
life.
Capture of a new peak value. This annunciator will remain lit for
a few seconds.
Depending on permission
settings and/or revision of
firmware, various soft keys
may be in a different location or
not visible.
lbf and kgf are units of force,
not weight. They will be close
to their mass counterparts, lb
and kg, for most applications
and at most locations.

EDjr Setup
One of the first things you should do to begin using the EDjr is to set it up to
suit your specific needs and equipment. You can access the Setup menu,
shown in Figure 3, using the soft keys. Press the appropriate soft key to
accomplish the functions listed on the following pages.

Setup
Misc Press the Misc key to access the following soft key set (refer to Figure 3):
Flash Press this soft key to enable or disable the “display flash”
feedback. If enabled, the press of a key causes the display to
momentarily flash to give you a visual feedback that the key was
activated.
Zero Press this soft key to enable or disable the Zero key’s ability to
also clear the Peak force value. If you enable this function,
press the Zero key to clear the Peak force and zero the load. If
you disable the function, the Zero key will only zero the load.
Peak force remains in effect and will only be cleared with the
Clear function during operation.
Contr Press this key to adjust the contrast of the LCD display. Press
the Down soft key to lighten the contrast. Press the Up soft key
to darken the contrast.
There is a keypad shortcut for increasing and decreasing
contrast. While in normal display mode press Arrow key and F2
simultaneously to increase contrast. Press Arrow key and F1
simultaneously to decrease contrast.
The next soft key is the About. The About menu shows an assortment of
information about your Dillon instrument. This can be handy for maintaining
calibration, troubleshooting or determining if the firmware can be upgraded.
Press this and access the following soft key set (refer to Figure 3):
Device Press this to see software revision and dynamometer informa-
tion.
Calib This soft key access the following soft key set:
Points Press this key to display the calibration loading points.
Setup
About
Dillon suggests that calibration
data be recorded and saved.
Sometimes the individual
soft keys are referred to as
the F1, F2, F3 and F4 keys as
numbered from left to right.

Test
O.Load Lists the number of overloads that have occurred since the unit
was manufactured.
Zero Lists the current zero point compared to the calibration zero
point. If the zero point has moved significantly, this may indicate
a serious overload has occurred and the instrument should be
returned for service.
The Test functions can help service technicians remotely diagnose your
Dillon instrument by showing information on key internal functions. Typically
these menus will have significance only to trained technicians . You may
look at these menus without technical guidance, but the information may
have little meaning, or an error may be reported that may not exist.
Press this key to access several items described below (refer to Figure 3):
Batt Press this key to perform a battery test. This shows the battery
level in A-D counts and approximate voltage. Voltage is not
calibrated.
A-D Press this key to test the A-D section of the EDjr. You need to
apply force to change the counts and test the unit. The A-D is
the electronics portion that converts analog load cell signal to
digital numbers.
Disp. Press this key to perform a display test. Stop the test by press-
ing the ESC key.
Keys Press this key to perform key tests. Any key pressed will be
reflected in the display. Press ESC to end the test.
