All Formotion Compass compensators
have been set at the factory to the neutral position and may be
perfectly calibrated right out of the box for your car, boat or RV.
Compensating Instructions:
It's easier
than ever to compensate the new Formotion Auto Compass because all the adjusting screws
are reachable while the compass is attached to the car!
1. Attach the compass in the desired
mounting position.
2. Head NORTH, turn the N/S compensator screw very slowly until
the dial reads "N".
3. Head EAST, turn the E/W compensator screw very slowly until the
dial reads "E".
4. Head SOUTH, if the compass does not read exactly "S", turn the
N/S compensator screw just enough to remove only half the error.
EXAMPLE: if the reading is off 2 marks on the dial, then adjust it
to make the dial read only 1 mark off.
5. Head WEST, if the compass does not read exactly "W" then follow
the same instructions as in line 4 using the E/W compensator
screw.
NOTE: Use only the adjusting tool or dime to adjust the
compensating screws. DO NOT use a steel screw-driver (This will
affect the compass magnets).
IMPORTANT:
The new Formotion Auto Compass internal
magnets are very strong. We did this because they are
designed to be used in motorsport applications that can incorporate a lot of
metal and or other material that can produce false readings or
even stop the compass from working properly at all.
The Formotion
Auto Moto Compasses strong
internal magnets helps eliminate unwanted distortion from the
surrounding metal on your vehicle but means that you have to be
very sensitive when you turn the compasses compensating screws
to calibrate your compass: a little is a lot on these settings.
When the compensating screws are at
a horizontal position they are considered in the neutral
position. Start with both screws in this position.
Follow the instructions above, but be careful not to turn the
screws too much: never turn the screws fully vertical as this
positions the internal magnets at the compass ball in a very
direct and strong way and you may find that it is so strong that
the compass may not spin freely. Your settings should
always be degrees OFF the vertical position either way.
Remember, turn the screws very little for each calibration step.
