3.5 Semi-Conductor Test (

1. Connect the measurement leads to the instrument's
terminals, complying with the polarities indicated: red lead
on the "+" terminal and black lead on the "COM" terminal.
2. Set the rotary switch to "
on the yellow key: The
3. Connect the unit to the semi-conductor (junction) to be
tested.
The measurement current moves from the "+" terminals to
the "COM" terminal. It corresponds to the direct testing of
the semi-conductor junction.
- Short-circuit junction: audio indication for a threshold <
0.050 V
- Cut or reversed junction (or threshold > 3.2 V) : OL

1. Set the rotary switch to position "A
2. Clamp the conductor carrying the current to be measured,
check for proper closing of the jaws and for foreign bodies
in the gap.
For DC, the " " arrow engraved on the jaws must be directed
in the presumed direction of current circulation for the sign
of the displayed value to be significant.
