I change the leads for new ones every year as part of maintenance program these leads have already been tested.

In house PAT testing kit
All you are testing is the ability of the cable not the equipment it is attached to.
Used to do all the PAT testing at a company I worked for many moons ago (20 yrs).
That goes without saying, Multiple Earth Paths ability: It is important to choose a PAT tester with the ability to make accurate earth bond measurements, even when multiple earth paths exist. Most PAT testers can measure earth leakage over multiple earth paths, but this is not the same as checking the integrity of an appliance's main earth. For example, consider the common office computer, which often has several other devices attached to it via a screened data cable - for example a printer, monitor or scanner.
An earth return path can still exist even if the earth bond wire in the cord of a computer is faulty.
If you buy a PAT tester that does not automatically cater for earth bond measurement under Multiple Earth Path conditions, the only way to ensure you are actually testing the earth bond of the computer is to disconnect it from all other ancillary equipment. The end result is an increase in test time, and a significant reduction in the number of tests you can do in a day.
Summary: On Servers it would be a visual or actually shutting them down before testing. Some third party PAT testing companies do not follow the rules as they are only in it for the money and so you get a thread like this.
