Considering "Ease of use" when selecting dielectric breakdown voltage tester
(1) An instrument that is difficult to use is not just an irritation, it also wastes time and reduces productivity. Look for an instrument that has a clear and straightforward user interface. Operation of the instrument should be intuitive and it should not be necessary to repeatedly refer to the user guide. This is particularly important for instruments that are made available for hire, and in cases where they will be used by engineers and technicians who do not perform oil tests regularly. Here are some specific points to consider.
(2) User interface. The user should be able to easily identify and access the main functions of the instrument, such as test method selection, test sequence set up, stored data functions and user settings including, for example, the operating language.
(3) Display. The display should be clear and bright, and preferably in colour. The display is a window into the functioning of the instrument - the bigger and clearer this window is, the better.
(4) Test chamber access. Good test chamber access will aid instrument operation and cleaning. Deep and dark chambers are bad, not least because they make it difficult to see if the chamber is dirty. Most users prefer top access instruments.
(5) Automatic testing. Most modern instruments support automatic testing, and will follow the test sequence specified in the chosen test standard with little or no operator intervention. Low-cost manual instruments are still available, but think carefully about day-to-day operation is needed before purchasing one of these. They may be appropriate for some users, but a high degree of skill is needed to use them successfully.
