Hi All, I got a megger TPT220 Really pleased with it. It has a LCD display for the voltage, plus the entire display flashes red and it beeps at the same time. It has a phase rotation tester built in, if you use it in a dark location the display has a backlight that AUTOMATICALLY comes on [there is a built in light sensor] plus there is a built in torch that you can switch on and off to obviously light up where you are sticking it if it is dark. Plus, the best feature of all, it DOES NOT trip rcd's. So, when you use it to quickly test polarity of a live circuit, say at at the end of a submain or at a DB you are working on, just to "make sure" [as i always do] as part of isolating and then "checking dead" it will not trip any upstream rcd's mid test.. Unless of course you actually want it to, so you can see if an rcd is at least functioning, when all you have to do is press a button on it and it will switch in a 30mA load, and off goes the rcd!!!
Really really pleased with it,
