6.
If you cannot see the scored line, then the goal is too low. Place your finger and thumb on the shaft,
directly under the housing, and pull the tester at an angle toward you. The shaft will extend further,
revealing the scored line. You can then estimate the height discrepancy.
7.
If the scored line is visible below the housing, then the goal is too high.
8.
The goal height should be adjusted to 10'-0". See instructions included with backboard support to make
adjustments as required.
9.
After all adjustments are complete, replace the measuring shaft into the housing, making sure the knurled
handle is once again tightened.
Testing of Basket Rebound
1.
Test competition baskets for proper NCAA (or FIBA) rebound range – 35 to 50% on each basket. Later,
you will check the difference between the two baskets – it must be no greater than 5%.
2.
Basket testing is best achieved by holding the readout box in one hand, and dropping the weight with the
other hand. IMPORTANT – When dropping the weight, keep hands, fingers and cord clear of tube
enclosure to avoid possible injuries or damage to the unit.
3.
Press the
MODE
button and the message
Test Bskt 1
will appear on the readout
(Photo M).
4.
Press the
EXECUTION
button and the message
Bskt 1 Drop # 1
will appear on
the readout.
5.
Press the
EXECUTION
button and the message
Raise Weight
will appear on the
readout.

6.
Hold the unit in a vertical position. Raise the weight to the stop collar, then drop the weight. The
percentage of the impact energy absorption of the rim will be displayed. Note – Stop the weight from
bouncing before performing second and third drops.
7.
Repeat Steps 4 through 6 for Drops # 2 and # 3.
8.
Press the
EXECUTION
button and the average of the three
drops will appear on the readout (Photo N).
Press the
5
EXECUTION
button again and the readout will indicate if the
backstop passes or fails (Photo O). If basket 1 fails, the goal will
need to be adjusted (per the manufacturer's instructions) or
replaced.
IMPORTANT – The weight must be allowed to come to rest on the
spring in the housing between trials, to quiet the vibration of the
spring. Neglecting to do so may produce erroneous measurements.

Repeat Steps 3 through 8 (
Test Bskt 2
) for the second competitive rim and goal support equipment.
