 At nearly 200 Euros (and possibly VAT on top - there didn't seem any point checking at that pricing level) for the Voltcraft version, I decided to spend my money on the Banggood offering, namely the OWON XDM1041 USB model for just £96.46 plus  a little extra on shipping and tariff insurance (still just under the 99 quid mark with an estimated delivery by the 29th - a realistic estimate going by recent past experience).

It is currently 139,99€ with VAT and shipping included. Add VAT and conversion to € for your Banggood offering, you are about level.

Johnny B Good:
 I just checked the currency exchange rates and I reckon I saved close to £20.00 on the deal (Banggood only show VAT inclusive prices, at least to us Brits). What I'd paid, was the equivalent of 119€ in total with no further charges added on.  :-DD

Johnny B Good:
 The XDM1041 I'd ordered from Banggood arrived this morning - three days sooner than Banggood's estimated delivery date. :)

 I haven't tested everything but it seems to be within its specs on DC volts and K-type temperature readings. The standby energy consumption is a gratifyingly low 250mW, peaking to a maximum of 1.5W at a backlight level of 100% dropping to just below 1W at 0% and just a fraction over 1W at the 25% setting.

 I'm monitoring the EFC voltage difference against my GPSDO's internal +2.0000 voltage reference offset which is hovering around the 366.00mV mark (2.36600v) closely matching the mV readings of a Mestek DM91A 9999 counts true RMS dmm I'd been using to see these variations down to a resolution of 0.1mV.

 I could use it to monitor the full EFC voltage (2.3660 volts) direct but I'd end up seeing only the same effective 100uV resolution I was getting with the Mestek DMM and a +2 volt offset.

 The only thing that had initially put me off buying this 4.5 digit bench meter was the lack of any tempco specification, hence my pushing the boat out on an SDM3065X which has impressively low tempco figures.

 In this regard, I don't expect the Owon bench meter will do any better than the Mesteks which, until I had cause to test their temperature stability a few months ago, had seemed remarkably stable in the face of typical changes in room temperature.

 At least the Owon bench meter isn't going to incur regular changes of a pair of AAA cells every 400 hours of run time (I usually disable the auto shut off time out feature built into the Mesteks to avoid losing sight of whatever I'm monitoring for hours long periods).

 I'll give the Owon a more thorough work out later and report the results here in a follow up post.

Johnny B Good:
 I completed my tests and, with the obvious exception of capacitance measurements being extremely slow to obtain results, everything else checks out with remarkably good accuracy against the SDM3065X.

 The only real complaint I have is in regard to the slowness (glacial) in producing capacitance readings. The accuracy of capacitance measurements is on a par with those obtained with other test meters so no complaint there - it's just the very long time required to get the reading that's so intolerable.

 Luckily, I have much better alternative ways to test capacitors, so this is very much far from being a "deal breaker" (as I suspect will (should!) be the case for most other purchasers).

BugCatcher:
Hi John,

happy to hear that you like your new "investment"!
I'm eager to get the following information:
Which FW-version is running in your box?
