Am in the middle of a large factory pir. When compairing results from the previous test sheets from 3 years ago, we have found many results vary some by quite a bit.
I must admit that the previous sheets do look a bit dubious to say the least, with only IR and earth loop being carried out.
My question is how should i put this down on the test sheets, the fact that there are so many differing results?
