OWON XDM1041 the unknown multimeter...

martinr33:
The original photos of the innards (on the brochure) show a power supply integrated with the PCB.

So we are looking at some kind of fix here. Esecially with the corner rounding and cutoff on the board - that's a reworked board from another design.

Wow, that's an ugly fix! It seems rushed and desperate to put product out.

theHWcave:
I just got mine thru Ebay, straight from China to the UK, took about 2 weeks although the seller said 4 weeks.
Interestingly, my power supply is exactly like in the brochure, no ugly fix
but they cheated on the fuses, instead of 2 decent 30 mm long high rupture ceramic as in the brochure, I got cheap 20mm long ones rated for 250V only, at least the 10A is ceramic.

Other than the slowness already mentioned, the meter is quite ok for what it is. After a weekend of intense testing my summary is:
the negatives:

* Capacitance above 500uF, auto range is not always working and one has to do manual ranging... capacitance is definitely the weakest mode anyway, the lowest range is just 50nF and 500pF or less shows only zero
* Ranging in volt mode is weird: it can auto range from the millivolt up to volts but not down from volts to millivolts. Same with manual ranging. To go from volts to millivolts or back you can't use the range up down, instead you have to select between volt and mV mode. You can get used to i, but interestingly this is just a problem of the user interface. The behaviour over SCPI is much more sensible, you can just go up and down using the RANGE command or use the CONF command without any issue.
* Rel mode is actually a maths function which means you can't have rel active and do averaging or dB/dBm at the same time since only one function can be active at a time 
* No smart data hold which would have been easy in software..., just a silly run/stop button which is like a dumb hold 
on the plus side:

* I really like the temperature mode. Very comprehensive and can do PT100 or K-type
* The SCPI interface (RS-232) has its quirks, syntax wise, but once figured out, it works well and can deliver more decimals than shown on the display. Using that the accuracy is pretty good.
* The display is easy on the eyes, especially if those eyes are not as young anymore...
* It fits exactly under the first tier of the shelf at the back of my bench. That space is very shallow and very low, which is why I got this meter for it. It does not take any extra space on the work area, its mains powered and can be on the whole day, and its display is exactly at the right angle .
And if you have not guessed it... the meter is always on as long as it's plugged into mains.The power switch on the front is only a soft-switch, but I measured the "standby" current to be only about 1mA at 230V, so its not too much of an issue.

coromonadalix:
would be nice if Owon could read this thread and improve the meter in a fw update ??

msquared:
It's finally official.

Also looks like there's already a newer version with a USB data port instead of RS232.

So much for being an early adopter. Maybe time for a little internal USB mod...
