Learn how to PAT Test (portable appliance test) a PC… First of all – unplug the machine. To PAT test the PC it needs to be disconnected from the mains and plugged into a PAT tester. By doing this, the PAT tester will be able to obtain electrical readings and generate a PASS or FAIL result.
First, PAT test the power cord…
When PAT testing a PC, the power cord is always tested first. The standard lead test consists of 4 steps: a visual inspection, an earth continuity test, an insulation test (500V DC) and a polarity test.
Then, PAT test the PC…
Once you have completed the led test sequence, you then test the computer with its own lead. Plug the computer into the 13A socket on the PAT tester using its own power cord and connect the earth bond lead to bare metal, which can normally be found in the back. The test sequence for the PC consists of three steps: a visual inspection, an earth continuity test (100 or 200mA) and an insulation test (500V DC).
It is worth mentioning here that PCs should not be tested with a test current which exceeds 200mA, as this vould potentially damage the motherboard. Also, you might use the leakage test, instead of the insulation test, if the PC you are testing is quite old.
Of course, you might want to learn from an expert on a one-to-one level. Our Portable ApplianceTesting training courses can be carried out the comfort of your office, or at our premises. PAT Courses can be booked as group booking or individual sessions.
