11. The chair will probably stop when you arrive
at the edge, but still keep the joystick
in exactly the same position.
Press UP
12. Press the UP button on the HHP until you
can feel that the front wheels try to pull up the
edge. Every time you press UP you will
feel this more.
13. Press “UP” SLOWLY until the chair smoothly
climbs over the edge with the joystick still in
exactly the same position as in step 11.
14. Turn the powerchair around and drive
to the location of step 1
15. Push the joystick forward to go over the
edge. If load compensation has the
correct value, the chair will not slow down
much, it will go smoothly over the edge.

16. Press EXIT to save the motor resistance
17. Turn the DX System OFF
18. Disconnect the HHP.
Notes:
1. This test procedure causes the motor to become hot. For this reason
the resulting value for Load Compensation is too high. Reduce Load
Compensation by 20% to make sure that the powerchair is not
uncomfortable to drive when the motor is cold.
2. A new motor usually has a higher motor resistance than a motor
that has been used for some time, because the motor brushes that
are inside the motor do not make optimal contact until they are
"worn in". If possible, perform this procedure when the motor has
been used for several hours.
