A PAT tester, or portable appliance tester, is an electronic device that is used to check electrical devices for faults in a wide range of working environments. They will provide a pass or fail for the appliance you are testing immediately, so you know it's safe to use. You can find more information about PAT testers and PAT testing in our complete guide to PAT testing equipment.
A lot of electrical safety issues can and are detected by visually examining the appliances, but some will only be found by PAT testing. By testing your portable devices by visual inspection and with a tester designed for the purpose, the risk of potential safety problems such as shock and appliance failure are reduced. PAT testers can be calibrated to ensure maximum safety, as they can deviate from the manufacturer's settings. Resulting in inaccurate readings could be the difference between a pass and failure. RS offer a UKAS calibrated service as well as our very own calibrated approval (RSCAL) for pinpoint readings.
PAT is a key component of the Electricity at Work Regulations in 1989, which requires employers or the self-employed to do anything that is 'reasonably practical' to protect people from harm. The regulation does not specify the frequency of the testing. Therefore, the testing should be carried out according to the environment and purpose of the equipment.
Deciding on the right PAT tester for your needs, you should first think about what you will be testing. Different models offer testing on different equipment. Some PAT testers can be used for Class I and Class II appliances, power leads, extension leads and RCDs. Many models include one-touch testing to return a pass or fail result, which can increase the number of tests that can be done in one day. You must also consider what voltages you are testing when selecting the right PAT tester.
