Different Types Of Circuit Testers

Electrical circuit testers and meters are diagnostic tools that can determine whether a circuit is properly grounded or not. They can also determine if there is electricity running through a circuit.

A circuit tester is made of 2 insulated wires and a small neon light and is commonly known as voltage testers, test lamps, test lights or neon testers.

These electrical tools are a basic and crucial tool no matter of the type of job. To ease your search, we have prepared a buying guide that will show you to the most common electrical testers and meters and its use. Have a look at it.

Electrical Circuit Testers

  • Voltage Testers – The voltage testers can detect the presence/absence of electrical voltage in cables, circuit breakers, wires, light fixtures, switches and outlets.

  • Non-Contact Voltage Testers – These types of testers can read the tested wires and devices without touching the wires. They give off a light or emit a sound when voltage is detected, but do not give a numerical reading of any present voltage.

  • Electronic Voltage Testers – The electrical voltage testers can measure AC ( alternating current) and DC (direct current ) and give a numeric reading of the present voltage.

  • Circuit Breaker Finders – The circuit breaker finder is a tool that can determine the circuit breaker that control the outlet. They contain two parts – a receiver and a transmitter. The transmitter is plugged into the outlet and the receiver is passed over the circuit breakers, so when the transmitter passes over the correct breaker, it shows a light or emits a sound.

  • Continuity Testers – These testers are used to determine a malfunctioning of a light switch. They can measure whether the electrical circuit is open or closed. A light switch circuit is open when the light is off and is closed when the light is on and. Closed circuits have continuity, so they can conduct electricity, while open circuits cannot conduct electricity. Make sure the power is turned off to a circuit before performing a continuity test.

  • Receptacle Analyzers – Plug the analyzer into an outlet to find out whether that outlet is working safely and properly.

Meters

  • Multimeters – The multimeters perform several tests in a single unit. They come with red and black lead testers and attached probes to the ends of wires. A single multimeter can take the place of a voltmeter, an ammeter and an ohmmeter and can measure voltage, current and resistance making it and effective and affordable tool for any homeowner.

    There are digital multimeters that can display measurements as a number and analog multimeters that display measurements across a bar making it harder to read.

  • Clamp Meters – Clamp meters can measure current, but today there are many other types of clamp meters that can be used for measuring temperature, voltage, temperature, etc.

  • Low-Voltage Meters – They are used for testing different types of connections in the following cables: coax, cat5, cat5e, cat6. These meters can diagnose troubleshoot problems in computer networking cables, phone lines, television signal cables, home networking cables, and audio/video distribution cables.
