Megger streamlines PAT testing for professionals

The testers are fast to use, light to carry and feature an internal database for results storage.

Key benefits also include rapid start up, instant restart after temporary disconnection when moving between test locations and optional barcode support to aid rapid asset identification.

Megger's professional PAT tester range comprises three models: the PAT410, which is an ideal choice for use in office and IT environments; the PAT420, which is equally at home in commercial, industrial and construction environments; and the PAT450, which is optimised for use by service organisations and tool hire companies.

The new testers offer both manual and automatic operation and, when they are used in automatic mode, the test structure can readily be configured to suit specific requirements.

Supervisors can pre-define a test structure for a specific application, and then be sure that all tests are performed exactly as required, irrespective of who carries out the actual testing work.

Efficient handling of test results is another characteristic of these instruments.

They have an integral multiuser database with ten times the capacity of a typical downloading PAT tester, and they use a flat data structure that enhances traceability as well as making it easy to set up assets and to find the data associated with them.

Results can also be stored in test groups, and there is no limit to the length of the group names.

These can be made descriptive and easy to understand, which is an important aid to testing efficiency.

Tests offered by the PAT410 include earth continuity (bond testing), 250 V and 500 V insulation tests, VA, alternative leakage tests and RCD trip tests for portable RCDs, anti-surge leads and power cords.

The instrument is designed for testing 230 V assets, and bond testing is carried out at 200 mA, which is suitable for IT and office equipment.

The PAT420 adds facilities for testing 110 V assets and for carrying out bond tests at 10 A and 25 A as well as at 200 mA, while the PAT450 offers all of the facilities of the PAT420 plus 1.5 kV and 3 kV flash test functions.

Megger's professional PAT testers are supplied as standard with a calibration certificate, printed quick start guide, full user guide on CD, continuity/earth bond lead and probe and a 13A extension lead adapter, all presented in convenient carrying case with an integral lead/document pouch.
