Pat testing equipment used for this purpose comes in a vast variety, and it is important to choose the right one suitable for the individual or organization’s needs. Here we discuss the various options available in the market, each with their pros and cons. pfe tester

Simple Pass/ Fail Pat Testing Equipment:

These are the most basic forms of testing systems available. The result of an appliance’s working condition is displayed only in terms of either it ‘passed’ the test or it ‘failed’. These systems serve well for small units where the appliances to be tested are less and not sophisticated. If looking for testing equipment that would provide a more detailed test, this system fails on that. The numbers of tests it offers are also limited- the basic tests possible on pass/ fail type are the insulation resistance and earth continuity tests.

A major drawback is that one may encounter a false negative result. The earth bondage limit is fixed in this form of Pat testing equipment, and often appliances with long leads fail the test, even though they are in perfectly good working condition.

Manual Pass/ Fail Pat Testing Equipment:

These testers are a step ahead from the type detailed above. Although, these too function ultimately on a pass/ fail system, the testers belonging to this range offer greater functionality. For example, the current in the earth continuity test can be selected, and is not fixed like in the basic forms. Added features bring with them a requirement for the user to have adequate knowledge and skill to operate the manual testers. Staff handling these must have proper training.

Automated Pat Testing Equipment:

Pat testers of this kind are the latest additions to the electrical testing system. Results recorded from computerized testing equipment can be saved and loaded onto a PC. it is of great help when the number of appliances to be tested are many, as it offers rapid reading of multiple equipments. In-depth analysis can be carried out later. Most come equipped with large memories, so one can take readings of many appliances before having to assimilate on the computer. The most fundamental edge that these computerized systems provide is that they allow measurement of earth bond readings in form of true or absolute values. This makes the task cost-effective and less time consuming.

Buying the correct testing equipment for your appliances will, therefore require good groundwork and research skills. The number of appliances to be tested and the level of safety one wishes to check form important parameters in deciding from amongst the vast array of products available.
