Do not buy DM3068. Unlike with Rigol oscilloscopes there is only small price difference. And their service was total crap after it failed on me less than in two weeks (was sent to Germany few times). Took more than 6 months being away in total and a bit of cheating on my side - destroying AC ranges completely to get it finally exchanged. They tried to prove me that it was within spec although last 4 digits on AC voltage/current ranges were useless jumping garbage. Replacement was dirty refub (even hard to call it refub) with PCB burned and one pad coming off under TVS diode which they replaced. And that with my original meter being almost new, just travelling back and forth. As of strange things, there were few bodge wires in my original meter but non such in the replacement unit although replacement was month or two older and with the same PCB revision. Dark stuff on the photo are not flux residues, I cleaned most of them before making photos duh, looked uglier. It is burned PCB with solder mask which came off near the pads (from the beginning, before I removed TVS to see what's under it). Also in the replacement, PCB was really dirty, Like if coated with the dirt form "crap spray". If you see the last photo from original meter, except bodge wires, there are flux residues all over analog stuff which IMO is not acceptable in 6.5 digit DMM. Just remembered, DM3068 input leakage current is really high with 10 Gohm input resistance setting. Around 100 pA IIRC with 50pA typical in the datashet. On other hand on my 34461A it is tiny, one of the advertised features BTW.
