The Meter UT106 is a tool for the very effective diagnosis
of the troubles with the electronic systems of the
automobile. This part gives a special introduction as to
how the Meter UT106 is used to diagnose any trouble

Set the rotary switch 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.
Short circuit the red and black test lead probes, when
the reading of the meter should be displayed between
0.2 and 0.5 . If it is more than 0.5 , check the test
leads to see whether they are well connected.

to the two ends of the fuse, when the reading of the
meter should be displayed less than 10 , indicating
that the fuse is good. When the display is overload
