4.
Pour only clear fluid into sensor. If fluid is dirty use a paper coffee filter or fine
screen to eliminate particles.
5. Slowly pour fluid into sensor until it is full. The sensor is full when the fluid just reaches
the bottom of the fill-port.
6.
Place Teflon

tape around the fill plug then screw it into the fill-port and tighten. Note:
the fill plug and fill-port have tapered threads designed to form a tight seal. Tighten the
plug just enough to prevent leakage - over tightening may damage the sensor housing.
7.
Sensor is now ready for use.
The different sensor fluids listed above will provide slightly different signal amplitudes
but their use will ensure that the magnetometer measures the magnetic field strength
correctly and that the sensor will not be damaged interaction with the fluid.
Geometrics
does not recommend the use of gasoline (petrol) as a sensor fluid. Experience as shown
that local formulation of gasoline may include additives that can damage the sensor. Do
not put any solvent containing acetone or toluene into the sensor: these will dissolve the
sensor body.
