In addition to the manuals that any electrician should possess , it is necessary to add :
- If the troubleshooting performed under tension :
- a voltmeter : device used to give an indication of the magnitude of the voltage .
there are two types of voltmeters longer use :
digital voltmeter analog voltmeter and
- ammeter (optional) : device used to give an indication of the magnitude of the current.
Types of ammeters :
- a test lamp neon : device indicating either the magnitude of voltage or polarity of the conductor AC (phase or neutral).
- a lamp with the same rated voltage as the supply voltage circuit dépannager .
- If troubleshooting carried off:
- ohmmeter : device used to give an indication of the magnitude of resistance.
- a lamp with buzzer or bell : apparatus for detecting circuit continuity ( . whether it is correct the unit emits a light signal and noise ) .
note:
He is a machine perfectly suited to the troubleshooting that is called " universal controller DIGITAL MULTIMETER or " It can measure . :
of trying - ( voltmeter ) .
- the current ( ammeter ) .
- resistance ( ohmmeter ) .
