Assembling the Air Track
1. Use the screws and Allen wrenches provided and
attach the single and double leveling foot to the Air
Track U-channel as shown in Figure 2.
2. Install one end stop at
each end of the Air Track
using the mounting
screws included in the
accessory tray.
Leveling the Air Track
Place the Air Track on a stable, level table and rotate
the two adjustable feet until the Air Track is as level as
possible. A bubble level may be used to approximately
level the track.
The final leveling, however, must be accomplished in
the following manner:
➀
Connect the Air Track to the Air Supply and turn
the Air Supply on.
➁
Place a glider in the middle of the track without
initial velocity.
➂
Adjust the leveling screws until the glider remains
at its initial position, not accelerating in either
direction.
➦ NOTE: The glider may oscillate slightly
about its position. This movement is caused by
air currents from the air holes in the track and
should be considered normal.
Adjusting the Air Supply
The Air Supply PASCO Model SF-9216 is connected
to the Air Track by the air fitting on one end of the
track. The output of the blower should be adjusted so
that the glider just floats on the track. Excessive air
pressure may cause the glider to wander on the track,
even in the absence of an accelerating force.
The Air Supply will slightly heat the Air Track,
causing it to expand. The adjustment beam under the
track has been set such that the track will be straight to
+/- .04 mm when warm, or after 5 minutes of operation
with the Air Supply.
