As a qualified PAT tester I "always" test "every" socket in a standard mains extension lead during a test, and when I train people in PAT testing I "always" make a point of encouraging them to do the same. Would've probably been prudent to highlight this point in this video - just saying!
Can't understand the point of doing an insulation resistance on a plastic class 1. What are you even testing if it's not connected to an exposed conductive part? Can it even fail?
I would love to know how this even qualifies as a PAT tester, it has a FAIL threshold of two Meg on a class one device according to the manual, yet the official threshold is one Meg. On a class two device it has a fail threshold of four Meg, when the the official threshold is two Meg, this all seems so very wrong when other testers are correctly calibrated, and this one seems to pass items other machines would fail.
Hello Ken, The fail thresholds that you have quoted are correct. The PAT tester will fail any Class 1 item which shows an insulation resistance of 2M or lower. As the tester doesn’t display any numerical values, there is an added safety buffer of 1M on the Class 1 test and 2M on the Class 2 test. For example, assume you are testing a Class 1 item with an insulation resistance of 1.1M. If you were using a tester with a numerical readout you would realise that this is very close to the fail limit and would probably fail the item. If the limits on a Pass/Fail tester such as our BattPAT was set at 1M, it would show that the item had passed, but there would be no indication that the test result was very close to the limit. For that reason, we have a threshold of 2M. This means that in our example, the reading of 1.1M would show as a Fail, which gives an added margin of safety in the absence of a numerical display.

This seems to pass everything? Even if the plug has no fuse?

Doesn't it show false readings on microwaves?
I found that too
