I saw it ages ago but have not yet tripped over it when using the meter, that I've noticed :-\ --- End quote --- Oh, that will be great for me! I'm planning next week to buy a 5 1/2 digit one, but rebranded as "Multicomp Pro MP730028". Waiting for your test results, or even a small video if you can... Thanks! |

From the Video, I can't get the Owon to read bad resistance values (it was left to warm up for thirty minutes, but it still read the right value from 'cold'), I've tried switching between VDC/VAC, Current, Ohm's/continuity/diode, Capacitance, Frequency and Temp and back. I've tried high, middle and low update speeds as well: My BM869s The XDM3041 There is another video of 'features': Now this I did get some consistency from, the main input terminal acts like an ariel and messes with the resistance value (it should be open circuit) but reads odd values: Flickering from 'overload' to 72Mohm with both leads connected: With the 'Input' lead connected (does not happen with the 'LO' lead connected only), I then get the half value: It does not do this if using four wire (with kelvin clips connected) The unit is firmware version 2.12.0, not there appears to be any other firmware (that I can find) Hope this helps |

@Mouse69 Hi, thank you for your sharings! This week arrived my unit, which is a rebranded Farnell MulticompPro MP730028 5 1/2 digits. I tried the same things as in the two youtube videos posted previously and gladly my unit does not behave weird. Then I tried and played with all it's features and everything seems to work very well. The only odd thing about it was somewhere in the menu, a little typo "Cancle" instead of "Cancel". My unit has version V2.12.0. I also brought it to my workplace where I have a calibrated 6 1/2 digit Agilent and compared them: DCV measurement was identical on all ranges, ohms was lower by very little on all scales, DCI was higher by very little only for currents greater than few hundred mA. I didn't check AC stuff. Other thing I liked was the fact that it can count up to 238'000. As the Agilent is able of ~1'100'000 counts, it was a nice sight for me to see the same amount of digits while measuring voltages between roughly 11V and 24V. The only downside from my point of view (and I hope it will remain the only one) is the continuous noisy fan, which is very noticeable in a silent room/lab. |

Hello, guys! In my last reply here I had only good things to say about this DMM, but this week I saw (heard) something interesting and decided to share it with you. It does not bother me very much, but maybe someone else is planning to buy this unit and it may be his decisive factor not to do it. Please read the video description. |

Hello ! I'm back with some teardown photos. The overall build quality looks cheap, I only liked that I saw Omron relays and many AD ICs. The current listing price on farnell is ~520 EUR including VAT :( :'( You can judge yourself if it's worth the money. I bought it second-hand almost new for about half of that and I am glad I did it. Enjoy the photos! |
