Resistance Measurement (Ω); Semi-Conductor Test ( ) - Chauvin Arnoux F 07 Manual De Instrucciones

3.4 Resistance measurement (Ω Ω Ω Ω Ω )
1. Connect the measurement cables to the unit terminals.
2. Set the rotary switch to position "
on the yellow key: The
3. Connect the unit to the resistance to be tested.
Range selection is automatic.
To measure low resistance with accuracy compensate the
measurement cable resistance (see § 3.3).
Above 40 Ω, the display indicates OL .

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 position
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) : display
of OL .
