If the push button is hold for some seconds, the display will be switch back to the setup main
menu.
If the function TEACH is used there no need to adjust something in this menu.
12.4 Menu 4 – Set wheel circumference (SET CIRC)
The value Circ represents the circumference of the wheel in mm to which the magnet and the
speedometer sensor is attached to.
Measure the wheel circumference, e.g. with the aid of a flexible wire or a cord. Subsequently, add
a speedometer advance of 5% by multiplying the measured value by 1.05. A short push button
operation (one indicator light is illuminated) increases the chosen digit. A long push button
operation (two indicator lights are illuminated) change between the digits. If the push button is hold
for some seconds, the display will be switch back to the setup main menu.
If the function TEACH is used there no need to adjust something in this menu.
12.5 Menue 5 – Speed sensor teach - in (TEACH)
The sub-point Teach affords an automatic calibration of the speedometer. To use this function, the
vehicle must be driven constantly at exactly 50 km/h (31 mph) while a 5 second countdown
elapses. Start the teaching by a long push button operation (two indicator lights are illuminated).
The device stores the calculated values and returns to the standard display.
The resulting accuracy is depending from the reference speed accuracy during the teach count-
down. This fact may cause a inaccurate speed display if the reference speed of 50km/h (31mph) is
not hold exactly during the teach-in. Therefore the use of the conventional method (set pulse and
circumference) is recommended.
12.6 Menu 6 – Set unit (UNIT)
Within this function the display indication can be changed from kilometres to miles by pressing the
push button for a short time. The character “0” is standing for kilometres and character “1” for
miles. To leave the sub-point; engage the push button until the setup main menu appears.
12.7 Menue 7 – Show number of software version (STAND)
This point shows the current software version. Nothing can be adjusted. Leave this sub-menu
engaging the push button until the setup main menu appears..
13 Safety instructions
The motoscope tiny provides a lot of information at one time. Users consequently require a certain
"training" period in order to recognise all the given information quickly and correctly. Please do not distract
yourself by watching the instrument in public traffic. The user of the instrument is responsible for the
correct entry of all relevant data as well as for the adjustment of the speedometer and all other functions.
In particular, the fitting of the dry reed contact as well as the input of all calculation factors for speed
determination must do with great care. The user is also responsible for mounting the instrument, the
sensors, and all other accessory parts to the vehicle correctly and securely.
