Many things can degrade radio signals, such as brick walls, metal reinforced concrete, machinery and even
wiring within walls. Other systems such as wireless networks and cordless phones may degrade or interfere with
operation of the Cooper Instruments radio-equipped system. As an FCC approved instrument on a license-free
radio band, the instrument must accept interference received from other devices that share the same frequency
and airspace. If other systems are colliding, it is best to isolate the device(s) that cause the interference and
then take steps to eliminate the problem which may include relocation, conditional operation or retirement of the
interfering device.
10.5 Installing Spacers
High capacity dynamometers with shackles of 50,000 lbf/20000kgf capacity and up, use spacers, Figure 11, to
insure proper centering of the dynamometer for performance and safety reasons.
Figure 11. Spacer
Do not use the dynamometer with shackles if the spacers are not installed. The LTL 730 design incorporates an
innovative method to retain these spacers, if desired, to ease shackle installation.
Place spacer on a solid surface and use a hammer to start the roll pins into the two small spacer holes. See
Figure 12.
Figure 12. Inserting roll pin
Insert through matching holes in dynamometer body. Lay the dynamometer on the spacers on a solid surface
with the roll pins protruding from the top. See Figure 13.
Figure 13. Roll pins extending above dynamometer body
Position the holes of the second spacer over the holes and tap spacer into position. See Figure 14.
