Basic information
The FuelGaugePro –Bar Graph Display Panel is a display panel designed for displaying actual amount of
fuel in fuel tank in cooperation with FuelGaugePro - Float-free Fuel Level Sensor. It is mountable on
double-sided adhesive tape on the dashboard of motorcycles, cars, boats etc. For best visibility on the
direct sunlight and not blinding at night, the display panel have automatic brightness regulation.
After installation, the whole system needs to be calibrated (except bike specific kits where the system is
factory calibrated). Calibration data are stored in display panel.

Calibration
For proper working of whole FuelGaugePro system, the system must be calibrated. Calibration includes:
-calibration of low/high fuel level
or
-calibration with fuel tank shape compensation for unevenly shaped tank
What you must think on during calibration:
-Make sure the FuelGaugePro –Float-free Fuel Level Sensor, the fuel tank and all parts of fuel
system are on its final places and bike stands in its riding position (not on kickstand).
-Double check connection of all fuel hoses. Leaking fuel can be very dangerous.
-Make sure the petcock is opened. If your bike is equipped with vacuum controlled petcock, the
engine must be running during calibration to hold the petcock opened.
1.Decide what type of calibration you will need
a) Low/high fuel level calibration:
-FuelGaugePro calibrated using low/high level calibration measures well enough with most
motorcycle fuel tanks.
-The gauge shows the height of the fuel. Not the real amount.
-No need to drain the tank. Just mount the gauge, ride the fuel out and when you switch to
reserve, set the minimum. Go on gas station, fill the tank up and set the maximum.
-For this type of calibration follow step 2 and skip step 3.
b) Calibration with fuel tank shape compensation:
-More precise –every 10% of fuel is stored separately in memory.
-The gauge shows the real amount of fuel.
-Need to drain the tank, start the calibration process, fill 1/10 of the tank, store the value, fill
2/10 of the tank, store the value etc…
-For this type of calibration skip step 2 and follow step 3.

2.Simple low/high fuel level calibration
a) Low level set:
-Ride the gas out to the amount you want to gauge show as a minimum. You can use the
moment when you switch to reserve for example.
-Make sure the petcock is opened and bike stands straight.
-Hold the included magnet in active area of Display Panel as you see on picture on page 2 for
3-5 seconds. You should see the animation. When it ends, take the magnet out. The upper
segment is now on.
-Hold the magnet in active area for ca. 3-5 seconds until you see the animation (all LEDs from
bottom to top will light on) and take the magnet out.
-Now the low level is set.
b) High level set:
-Fill the tank to the amount you want to gauge show as a maximum.
-Make sure the petcock is opened and bike stands straight.
-Hold the magnet in active area of Display Panel for 3-5 seconds. You should see the
animation. When it ends, take the magnet out. The upper segment is now on.
-Proximity the magnet to the active area shortly (0.5-2s) and take it out. You should see the
two segments from the top are on.
-Hold the magnet in active area for ca. 3-5 seconds until you see the animation (all LEDs from
bottom to top will light on) and take the magnet out.
-Now the high level is set.
Note: You can do low/high level calibration separately whenever you want. You can also turn the gauge
off and on between low and high level calibrations.

3.Calibration with fuel tank shape compensation
-Fill the tank to the amount you want to gauge show as empty tank.
-Make sure the petcock is opened and bike stands straight.
-Hold the included magnet in active area of Display Panel as you see on picture on page 2 for 3-5
seconds. You should see the animation. When it ends, take the magnet out. The upper segment
is now on.
-Proximity the magnet to the active area shortly (0.5-2s) and take it out. You should see two
segments from the top are on.
-Proximity the magnet to the active area shortly (0.5-2s) and take it out again. You should see
three segments from the top are on.
-Hold the magnet in active area for ca. 3-5 seconds until you see the animation and take the
magnet out. Now you will see two flashing segments –top and bottom.
oNow the device is prepared for storing first value (0%).
oWe suggest to fill 0.2-0.5l to the empty tank to make sure all fuel hoses are filled up.
-Confirm 0% by proximity the magnet to the active area shortly (0.5-2s) and take it out. After
animation you should see the 1st bottom flashing segment.
oDevice is prepared for storing second value (10%).
-Fill the 10% fuel to the tank now confirm 10% by proximity the magnet to the active area
shortly (0.5-2s) and take it out. After animation you should see the two bottom flashing
segments.
oDevice is prepared for storing third value (20%).
-Repeat previous step for two flashing bottom segments (20%), three bottom flashing segments
(30%) up to ten flashing segments (100% of fuel tank capacity).
-Now the FuelGaugePro system is calibrated.

Flashing off means no segment is illuminated when the Display Panel shows empty tank.
Flashing on means first segment is flashing when the Display Panel shows empty tank (factory setting).
-Hold the included magnet in active area of Display Panel as you see on picture on page 2 for 3-5
seconds. You should see the animation. When it ends, take the magnet out. The upper segment is
now on.
-Proximity the magnet to the active area shortly (0.5-2s) and take it out. You should see two segments
from the top are on.
-Proximity the magnet to the active area shortly (0.5-2s) and take it out again. You should see three
segments from the top are on.
-Proximity the magnet to the active area shortly (0.5-2s) and take it out again. You should see four
segments from the top are on.

Troubleshooting
If you obey all the instructions, this fuel gauge should work properly without problems. In case of any
problems, feel free to contact us.
-If the gauge doesn’t show anything on the display, check out all the connections of the device.
-If the gauge shows nonsense and is calibrated correctly, try checking, if you filled up the fuel hoses
like explained on page three.
-Wrong data display is often caused by dirty fuel strainer in the fuel tank, dirty fuel filter if the gauge is
connected after it or just marginally opened fuel cock. In case of problems, try to check/replace these
parts. This fault is often represented by the amount of fuel dependant on engine revs. Pressure
sensor fail is very improbable –problems are usually caused by something else.
If nothing helps, contact us.
