The Megger PAT350 PAT Tester is capable of automatic PAT testing with pre-set test sequences and manual testing where the user selects the appropriate function as and when required. The tester performs standard tests such as earth bond (200mA, 10A & 25A), insulation resistance and polarity in addition to more advanced functions such as substitute/differential/touch leakage current measurement, portable RCD testing, load & run testing, and flash testing (1.5kV & 3kV).

An integrated 110V socket on the Megger PAT350 means that it can test industrial appliances such as power tools without requiring a separate adaptor. Individual buttons trigger individual tests or automatic test sequences for Class I and Class II appliances or extension leads. The bright colour display allows the user to navigate through various menus using the direction buttons and clearly shows a PASS/FAIL indication and numerical results.

The Megger PAT350 is a mains-powered tester but nevertheless has an internal back up battery that can power the unit for up to five minutes once disconnected from a power source, so it will be possible to finish a test in the event of a power cut. The tester is an ideal unit for commercial, domestic and industrial settings including production lines and repair shops.
