In the world of electronic equipment, appliances, and machines, the process of testing and tagging has become rather crucial. It is a process that requires a professional to test an appliance and also tag it according to the testing results. The entire process involves two primary steps. The first is to visually inspect an electronic appliance and the second is to test it with the help of a Portal Appliance Tester or a PAT.
Unlike common beliefs, the process of test and tag can be carried out by any person who is authorized to do so and knows how to use the PAT. Even if your local electrician has the necessary knowledge and skills, he can do the job for you. The testing and tagging of appliances is not a one-time process. It needs to be done on a periodical basis.
However, the frequency of testing and tagging of different equipment and appliances depend largely on the way these are used. For example, in a construction industry, where electronic machines and equipment are used in a rough manner, they need to test their machines once every 3 months or so. On the other hand, corporate offices, need to test their machines and tools once every year.
How to Test and Tag a Surge Protected Device?
If you wish to successfully wish to test a surge protected device, then you need to understand the basic way your tester works along with proper knowledge of how surge protection exactly works. Normally, surge protected power boards contain Metal Oxide Varistors or MOVs or/and Electro Magnetic Interference filtering or EMI filtering.
The main factor here is that you will have to perform a different type of test that will be based on the type of tester that you use and whether it contains EMI or MOV. It is important for you to understand that there are certain surge protected power boards that will contain both MOV and EMI filtering.
How to Test USB Chargers?
If you discuss with Adelaide ETS test and tag, you will come to know that there is a little confusion around the topic of how to test and tag a USB charger and whether these should be tested at all. It is important for you to visually inspect a USB charger and then electrically tested on the AC side of the transformer. Although these types of chargers produce low voltage DC current, these need to be tested, nonetheless.
You may often hear people say that low voltage items need not be tested. Nonetheless, you need to test the AC side of a USB charger or the side that is plugged into the wall. You also need to visually inspect the pins for protective insulation. Under normal circumstances, any type of fault will be visible during the Class II Leakage Test or Class II Insulation Resistance.
There are several other standards that you need to follow when it comes to testing and tagging various types of electronic tools, gadgets, appliances, machines or equipment.
