Megger makes Pat testing easier than ever

Their very short learning curve and their tough construction – they feature hardened, scratchproof glass to protect the display and rubber armouring for the cases.

Megger’s new PAT100 series testers are currently available in three models.

The keenly priced PAT120 provides all of the functions needed to carry out tests on the vast majority of commonly encountered portable appliances. It features pre-programmed test groups with fixed pass/fail limits for testing earthed and double-insulated 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.

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.

For users who need to test an even wider range of portable and fixed equipment, the PAT150 offers all of the functions of the PAT120 plus many others. The additional functions include tests for 10 mA and 30 mA portable RCDs, and separate tests for continuity, insulation, leakage and SELV equipment, all of which can be accessed rapidly via the quick-test button.
