There is an incredibly wide range of test equipment on the market, and there are some obvious benefits to some equipment, and some not so obvious pitfalls to other equipment.
Firstly, you need to determine how you want to see your results.
- Are you happy with a handwritten log of testing showing Pass and Fail?
- Would you prefer an electronic printed register with audited test history of each individual test conducted?
If you are happy with a handwritten log detailing Pass or Fail, then you might also be happy with handwritten test tags on your appliances, and therefore you can choose a provider that operates basic hand held test equipment or your local electrician operating equipment such as a Megger.
If you want an electronic register with fully traceable test results, then you will need to choose a provider operating test equipment that stores the test results. A provider using equipment that stores the test results will also be able to provide you with a detailed summary of the individual tests conducted on your appliances. In this way you can form an electrical history of your appliances, and not simply a register of Pass or Fail.
