PICKUP CARD INSTALLATION
The pickup card is an electronic circuit board that accurately senses each drum
revolution.
1
Locate the pickup card bracket on the right side of the dyno just ahead of the
drum.
2
Install the pickup card to the bracket using two No. 8 screws.
3
Align the optical pickup card with the wheel on the dyno drum axle. Be sure the
wheel passes freely through the optical pickup. You may need to loosen the
bracket to help with alignment.
4
Once aligned, tighten the screws to secure the pickup card bracket in place.
The optical pickup is very delicate. Be careful not to damage the optical
pickup during alignment.
