3 MECHANICAL SETUP
3.1 Loading shaft orientation
In order to accommodate a variety of testing requirements, the orientation of the loading shaft may be
oriented in either of the two positions shown below. To change the loading shaft orientation, loosen the
two captive screws on the back side of the housing, separate the two housing halves, rotate one half 180
degrees, and reassemble. Exercise care when reassembling the two halves of the housing, ensuring that
internal wires do not interfere.

3.2 Mounting to a plate
Although the dynamometer may be used by hand, proper mounting is important if attached to a fixture or
test stand. The round steel insert with a hole in the back of the housing is provided to withstand the load
during a test. A mating dowel pin should be used (see illustration below). An additional two holes are
supplied for metric screws. These holes are designed to accommodate screws in order to hold the
dynamometer in place. The screws must
not
be used for load bearing purposes. Failure to use a dowel
pin properly can result in a hazardous situation.
3.3 Mounting attachments to the dynamometer
The dynamometer
’s threaded loading shaft is designed to accommodate attachments with female
threads. To mount n attachment, gently thread it onto the shaft. Attachments may not orient in a parallel
manner when tight. In such cases,
do not over-tighten
, or damage will occur. Loosen the attachment to
the desired position, and use in this manner, or use a jam nut to prevent the attachment from rotating.
Use two wrenches to tighten a jam nut; the second wrench should engage the flat section of the load cell
shaft. This is to prevent loosening of the loading shaft, which can lead to damage.
