Introduction

The EDjuniorTM (EDjr) electronic dynamometer from Dillon is a force mea­surement 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.

If you overload this dynamom­eter you could suffer severe
injuries or death. The total load
on the dynamometer should
NEVER exceed the rated
capacity.

There are four “hard” keys and four “soft” keys. The hard keys are perma­nently 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.
