Had as an electrician, for example the following situation: A cable tray with 300 lines in it, the order was as follows: In the cup several cable layers that have not been used for years and we should remove them. However, we could not turn off the power at the factory since many things were produced. Well now we have been the end of cable and just had to figure out what the other end of the junction box is to separate it from the Storm. I lit at the end of the cable to the tester of red and colleague at junction box of a power protection switches are actuated by one the red light stops to shine. Maintenance switch again, off, from, (lamp red lamp, lamp red) OK, this cable is we close it off. That was quite handy with the Fluke. But for example, it was a 100-percentage indicator for example use to determine if something is live I would not recommend, this is too vague. In a sheathed cable the current-carrying wire never expires so bolt upright but times up times down, even if he does not show the cable to the Fluke Encircled particularly reliably if power is there or nicht.Soll not mean now that the device incorrect values provides, but when certain things affect the power I'd like as an electrician with a real meter to be certain.
