Model UT106: OPERATING MANUAL
Move the Hall sensor out of the automobile and see
the details of the operation in various kinds of
automotive manuals.
Connect the positive pole of the 9 V battery to the
source end of the sensor and the negative pole to
the ground end of the sensor by referring the details
to the positions of the source and ground ends of the
sensor in various kinds of automotive manuals.
Set the rotary switch of the meter to 200 . As
prompted at the LCD connect terminal, insert the red
test lead into the terminal and the black one into
the COM terminal.
Connect the red and black test lead probes in parallel
to the signal connect terminal and ground end of the
sensor and the meter should display a small ohm.
When a metal plate (blade, steel tape, etc.) is inserted
into a concave magnetic pole of the sensor, the display
of the meter will be enlarged or overloaded; if the
metal plate is moved away, the display will become
smaller, which proves that the sensor is satisfactory.

The functions of a magnetic resistance sensor is similar
to those of a Hall sensor and the testing methods of both
sensors are also similar. Their normal resistance is
generally in a range of 150 to 1 k . Refer to the ranges
of resistance in various kinds of automotive manuals for
the details.
