2. Electrical outlet tester - Wikipedia

   en.wikipedia.org/wiki/Electrical_outlet_tester

   A receptacle tester being used to check for some types of improper wiring of an outlet. For this particular tester, proper wiring is indicated by the two yellow lights. The outlet tester checks that each contact in the outlet appears to be connected to the correct wire in the building's electrical wiring. It can identify several common wiring ...

3. In-circuit testing - Wikipedia

   en.wikipedia.org/wiki/In-circuit_testing

   A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.

   Guidance is provided by the IET in the form of the Code of Practice for In-service Inspection and Testing of Electrical Equipment – 5th Edition published in October 2021. [ 15 ] In Australia it is a legal requirement, per AS/NZS 3760 2010, that formal PAT testing ( Test and Tag ) is performed by a competent person, with suitable competence ...

   Live testing. Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified by standards Insulation resistance testing Polarity test: a test to check that the connections are connected in the right sequence

   Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video signal generator: Generates video signal for testing purposes Voltmeter

7. Continuity tester - Wikipedia

   en.wikipedia.org/wiki/Continuity_tester

   A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; [1] that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus.

8. Growler (electrical device) - Wikipedia

   en.wikipedia.org/wiki/Growler_(electrical_device)

   to test series and interpoles (commutating) fields from a DC motor; to determine phasing and polarity in multiwinding armatures; to test rotors in rotating frequency changers, as well as in wound rotors; to test shorts between turns in taped coils before installation into an armature or a stator; as a low voltage isolation transformer

9. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   Any meter will load the circuit under test to some extent. For example, a multimeter using a moving coil movement with full-scale deflection current of 50 microamps (μA), the highest sensitivity commonly available, must draw at least 50 μA from the circuit under test for the meter to reach the top end of its scale. This may load a high ...
