The PASCO CI-6690 “A”-Base Rotational Adapter is
designed for use with the PASCO CI-6538 Rotary Mo-
tion Sensor (RMS) or the PASCO CI-6625 Rotary Mo-
tion Sensor for ULI. It is used to mount the RMS to the
“A” base of the PASCO ME-8951 Rotating Platform or
the PASCO ME-8960 Gyroscope. The Rotary Motion
Sensor provides higher resolution than a Smart Pulley,
and precession and nutation of the Gyroscope can be plot-
ted since the RMS keeps track of direction of rotation.
The adapter includes a mounting bracket, a shoulder
screw, a drive belt (o-ring) and a 3-step Pulley. The drive
belt links the 3-step Pulley mounted on the “A” base to
the 3-step Pulley on the RMS. For a one-to-one corre-
spondence, connect the two pulleys using the o-ring on
the middle step of each pulley. Each revolution of the
Rotating Platform or Gyroscope corresponds to one revo-
lution of the RMS. If desired, a 5-to-1 ration can be at-
tained by putting the o-ring on the top or bottom steps.

Assembling the RMS to the “A” Base
The pulley attaches to the underside of the rotating shaft
with the shoulder screw. Please note the pulley orienta-
tion as illustrated. The bracket connects to the “A” base
of the Rotating Platform or the Gyroscope and to the
RMS rod clamp.
