Resistance Measurement; Diode Test; Continuity Test - Würth MM 50 Traducción Del Manual De Instrucciones De Servicio Original

Resistance measurement

▸
Set the selector switch [9] measuring range to "Ω".
▸
Plug the black measuring lead into the COM jack [5].
▸
Plug the red measuring lead into the V/Ω input
jack [6].
▸
Connect the measuring leads to the test object.
The multimeter automatically searches for the most
3
favourable measurement range.
The measurement result is output at the display [1].

▸
Plug the black measuring lead into the COM jack [5].
▸
Plug the red measuring lead into the V/Ω input
jack [6].
▸
Connect the measuring leads to the test object.:
• Red measuring lead = anode
• Black measuring lead = cathode.
The forward voltage is displayed.

Continuity test

▸
Set the selector switch [9] measuring range to "
/ /Ω".
▸
Plug the black measuring lead into the COM jack [5].
▸
Plug the red measuring lead into the V/Ω input
jack [6].
▸
Connect the measuring leads to the circuit being
tested.
A beep is emitted for continuous electrical circuits
