The Digital Degree Wheel is an electronic device, with a digital reading, which enable a measuring of the diagram of the internal combustion engine, both of the two-stroke and four-stroke engines, at the tenth degree of precision. It is essential to know precisely all the distinctive corners of two-stroke engine as suction, exhaust, opening and closing of valves, the width of the valves of four stroke engines. It has been made to replace the traditional graduate degree wheel or goniometer and to work out the problem of precision, basic element when preparing competition engines. The PRISMA Electronics already realized in 1995 the first Digital Degree Wheel which then became the standard to measure the diagram of two-stroke engines.

Main Features:

•       Reading at the hundreth degree of precision - ex. 128,15°
•       High precision when measuring thanks to an extremely accurate encoder
•       Information about the battery-charge status
•       Dimension : 100x60mm
•       Backlit display to make sure an high visibility of the reading process even when you are in critical room
•       AA rechargable batteries powered wich automatically recharge themsleves as soon as connection with the feeder is estabilished
•       Coupling for attachment the engine controlled
•       Automatic power off after not having used for 5 minutes
•       High working autonomy

Particular function:

• Through the push-button MODE it is possible to evaluate how many revolutions the encoder has made and then it is useful to measure the gear in the 125 cc category.

Applications :
2 Stroke engine :
Timing port measuring
Gear shift ratio measuring

4 stroke engine :
Cam timing measuring
Gear shift ratio measuring

The Digital Degree Wheel is made up of the display unit which enables to catch sight of the outcome of the measuring through a graphic, monochromatic display 122x32 pixel and through the encoder. This last one is to be put on the driveshaft through the threded, little bushing, putting between them the plastic joint ( we supply you with ) wich enable to reduce the imperfect aplomb between the driveshaft and the encoder. To reach a perfect measuring it is necessary to consider a very important factor: the assembling of the encoder on the driveshaft must be as much as possible perpendicular so that during his spinning there won’t be any irregular movement wich could cause a wrong measuring. To this end it is essential to use the plastic joint you are supplied with to correct any lack of allignment.
