Continuity tester

Continuity tester- A device that tells whether a circuit is capable of carrying electricity. 

A d.c. test using an ohmmeter continuity tester is suitable where the protective conductors are of copper or aluminium up to 35 mm. The test is made with the supply disconnected, measuring from the consumer s main protective earthing terminal to the far end of each CPC, as shown in Fig. 4.32. The resistance of the... 

The test is done with the supply disconnected using an ohmmeter or continuity tester as follows ... 

Heating units are somewhat susceptible to failure. If a unit is bent, twisted, or dropped, the element inside the unit can be damaged and an open circuit will result in failure. Plastic buildup on a heater band can also lead to a failure. Finally, if the unit is on and there is an air gap between the heater and the metal surface, a hot spot can occur on the heater and it will fail. A heat transfer paste can sometimes be used to ensure good conduction to the metal. If a heating element is suspected to have failed, it can be easily checked offline with a continuity tester. A short or open circuit means that the heating unit needs to be replaced. 

An ohmmeter can be used as a "continuity tester," to determine whether or not wires are properly connected. More expensive meters often have a buzzer that...
