UT196 arrived at work... For appx 160€ it looks solid, but not the quality a brymen in this range do got. There are "air gaps" around the input, but this is not the input where you can measure up to 1700V. First test before giving it away for calibrating on the magna power 0-1500V supply. Martin |
| Kleinstein:
The combined Ohms and high voltage input could be tricky: the ohms part kind of needs a connection to the switch and there tend to be marginal creep paths. So the seprate higher voltage input with no ohms fuction is what make it relatively easy to provide a safe 2000 V range. It is still not safe from user error - but with 1000 V or more some case is advised anyway. |

The UT196 they at least splurged on MOV's and four pair of bigger SOT-89 clamp transistors. But the spacings for R1 2MEG are hilarious if you follow the pcb trace. We don't know if it's actually 61010 certified, Uni-T removed their certificates from their website after it revealed their dodgy practices. It's common practice to deceive and say "designed to" or "follows" 61010 but nobody ever tested it. Provide the certificate and file number if the multimeter has passed regulatory. It's very difficult to find a PTC rated for 1,000V and UL approved. Putting two in series does not work because they have unequal resistance and heating times. |

Larger PTCs as well. Are they using three MOVs in series for the V input side and two in series on the low voltage circuit? I have ran my BM869s up to 1.5kV but for a quick demo, the clamps start to conduct around 1.8kV and they don't blank the display. The prototype BM789 I have will run up a bit higher before it starts to clamp. I am uniquely qualified in the art of stupidity and am not suggesting anyone attempt to do this with your meters. It would be far better to buy a proper probe. |
