Extension Lead Test
PAT Testers with an inbuilt lead length calculator for long cables and extension leads will save a lot of headaches.
Downloadable
Generally, PAT Testers with a memory can be downloaded to reporting software. This can then be made into reports.

200mA
10A 25A
Earth Bond Test
The Earth Bond Test (Earth Continuity Test) is carried out on all earthed appliances. An Earth Bond Test shows whether the earth conductor is in a satisfactory condition.
Tests IT Equipment
This PAT Tester is suitable for testing IT and electronic equipment with a low current Earth Bond Test (usually either 100mA or 200mA).

10000
Tester Has Memory
This allows the tester to store an allocated number of tests. Results can be downloaded into reporting software but can only be viewed on screen if it is a manual PAT tester.
Mains Powered
These PAT Testers offer a wider range of tests and are powered by a mains socket.
Connects To Printer
A Printer can speed up your PAT Testing a great deal. If you require a printer, then you must choose a PAT Tester with printer compatibility.
110v Run Test
Most industrial and construction equipment is powered by 110v. A 110v Run Test (also known as Load Test) is required for this.
Connects To Scanner
A scanner can speed up your PAT Testing a great deal. If you require a scanner, then you must choose a PAT Tester with scanner compatibility.

250
500V
Insulation Test
The Insulation Test measures the insulation resistance of a device under test. A 250v Insulation Test overcomes problems in testing surge protected extension leads.

4.4Kg
Weight
If you need to walk between tests make sure you pick a PAT Tester with a comfortable weight.
