I recently got a UT210E also. It's nice to have the NCV which beeps to show voltages in proximity in a sort of graduated manner.. That as well as the 1ma clamp current measuring capacity are very nice to have and both seem to me they will help make the hobby safer. In the past with my UT61E for example, which doesnt have NCV I don't just start probing everything when I open up a device and apply power but with the UT210E I have been - as its so easy to just scan around with its tip and its good..You just say, okay, there are voltages here and here and here, that I should know about. Thats just really good as no thinking or examining the layout or schematic whatsoever is required to do that,
and there is no risk that that could damage anything either..
