Multimeters are the most versatile of the electrical testers and, as the name implies, they are capable of many different testing functions. All professional electricians own one of these tools. Most multimeters can provide precise readings of resistance, AC and DC voltage, continuity, capacitance, and frequency.
What is an electric tester?
An electrical tester can measure a variety of electrical parameters, from current and voltage to resistance, continuity and beyond. An electrical tester is used by electrical contractors to assess everything from live wires and circuit breakers to electrical panels and power transformers.
What is the purpose of electrical testing?
Testing is the only way to identify manufacturing faults that could compromise the electrical safety of a product out in the field. Thorough electrical safety testing protects against the risk of electrical shock, so that products can be used for their intended purpose with minimal chance of injury occurring.

Can any electrician do an EICR?
Only registered electricians should carry out an EICR.
Why is inspection and testing carried out?
Before inspection and testing is carried out
It is important to protect the safety of people, livestock and property against the dangers and damage that electrical installations can cause. In basic terms this means assessing risk of injury from things such as: Electric shock. Burns/fire.
What are the 2 types of currents?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.
