The PAT120 provides all of the functions needed to carry out tests on the vast majority of commonly encountered portable appliances, which is complemented by a new smartphone/tablet app which is available for Apple and Android devices. The app provides a concise guide to PAT testing, including risk assessment, determining retest frequency, and cable calculations for extension leads.

It features pre-programmed test groups with fixed pass/fail limits for testing Class I and Class II appliances as well as extension and power leads. The use of test groups means that the instruments carries out the correct sequence of tests automatically, with a minimum of operator intervention. Not only does this simplify testing, it also reduces testing time and guards against errors.

The PAT120 offers insulation testing at 500 V by default, but a 250 V option, which provides safe testing for IT equipment and surge protected devices, can be selected at the start of each test. Leakage testing is carried out using the “substitute” leakage method, which removes the need for access to a mains supply while performing the test.
