Testing the motoscope tiny

Motoscope tiny

Device doesn’t power on

First the Brown cable to +12V and then the black cable to ground.
The LED’s should now illuminate and the needle should do a whole rotation to 200 and back to 0.
If that’s not the case, the device might be defective and must be returned for repair.
Mind: During the tests, please ensure that the connection cable is not subjected to any tensile or compressive load at the point where the cable exits the housing.

Needle doesn’t rotate to 200 and back.

If the needle doesn’t rotate to 200 and back to 0 when switched on try the following steps:

If there is any force on the cable of the motoscope tiny/speedster/vintage.
It is possible that the mechanic of the tacho can’t work properly.
Battery voltage too low.
If the battery voltage is too low the functions of the motoscope can be impaired.
Plus, or ground contact not properly clean/attached.

Speed indicator

first the Brown cable to +12V and then the black cable to ground.
If the device is powered on, navigate through the setup using the green wire.
To enter the setup navigate to the display hour and hold the green cable against ground until you enter the menu.
Set Pulse (3) to 1 & Set Circ (4) to 2000.
Exit the setup menu by holding the green cable against ground until the hour screen shows up.
Now tap the orange cable against ground/plus. A velocity should be shown.
Depending on when the device shows a velocity the speed sensor must be connected to serve that condition.

Wrong speed is shown

If a motogadget sensor is used, it must be calibrated using the TEACH function.

If you don’t know whether your sensor is compatible, move the bike a couple of meters.

If a velocity is shown the sensor is most likely compatible.

Navigate to the point TEACH in the setup menu.
Drive 50 Km/h or 31mp/h and hold the settings button for 2 seconds. After that the TEACH function will be started.
The TEACH process takes 5 – 10 seconds depending on the device.
When the process is finished, the display will change back to km/h / mp/h
--> If there is no velocity shown the sensor might be incompatible or defective.
Please refer to the previous /next chapter to test both options.
Incompatible sensors are generally all 5V powered sensors, as well as hall sensors (such as BMW).

Revs aren’t shown correctly

Check the parameter ImpE und ImpF in the setup menu.
ImpF is a filter normalizing the tacho signal. Adjust it if the needle jumps while it should be steady.
If the revs are too different from the real value the ImpE needs to be adjusted.
The value of ImpE is depending on the cylinder count and number of ignition coils. Mostly values of 0.5 or 1 should be correct.

Connecting the speed sensor

After checking whether the speed sensor is plus- or minus/ground-active it needs to be connected according to the following instruction.

Minus/Ground-Active signal:
The motogadget Speed sensor must be connected to ground on one side. The other side needs to be connected to the input of the tachometer.

Plus-Active signal:
The motogadget Speed sensor must be connected to 12V+ on one side. The other side needs to be connected to the input of the tachometer.
