As they say everything has USB now... And now I have a Multimeter that has USB!

Specs



Usability


Well this is like any other multimeter, it has auto-ranging inputs, which combined with the large screen, makes it easy to use. All the buttons controlling the device are "soft buttons" switching between DC and AC is just as easy as pressing the button again. To switch from Hz to Temperature you just press and hold the button until it beeps! Turning on the RS232 Output is a tad bit harder, you have to press and hold the REL/RS232 switch. The Max and Min, and backlight are just the icing on the cake.

The most infuriating problem is that the Power Switch is a toggle button, which means when it's Auto-Power off turns the device off, you have to press the power button TWICE, which can be a pain if you are trying to view the stability of a rail [Auto power off is only disabled in RS232 mode]

Design


It's a tool for engineers... You'll never see an Art Student toting one of these. It's a ruggedised grey plastic case, with a High-Vis, orange rubber jacket, with a large quite thick perspex screen. Designed to withstand the torture that engineers will put it through.

Quality


It' has an amazing build quality. It's CAT II Rated device, and accepts up to 1kVDC and 750VAC. But who would want to hook up 1kVDC to a device connected to your computer...

Oh look, the USB port is Optically isolated! Which means the computer is completely fine if you hook it up to the mains since the clearance between traces are large enough that it would short on the input side before the USB side.
I tested it against some Regulated power supplies, Sparkfun's 1/4 Watt Resistor kit and all the values were bang on the rated values.

Software


Now there is a little bit of note here: The device is advertised as RS232, and the device does have RS232 output AND that's what the USB uses as it's data input. BUT the USB output is HID AND proprietary. And the software is a tad bit lowest bidder.

It's not multi platform software, Windows only folks! It's weird that they didn't develop for OSX, but it's no surprise they didn't develop for Linux.
It's annoying that the device has Auto-Ranging but the Software doesn't. Also the software hides all the files you save [Hint: Look in "%localappdata%/VirtualStore\Program Files (x86)\DMM V3.0\DMM V3.0" on a 64 Bit OS or "%localappdata%/VirtualStore\Program Files\DMM V3.0\DMM V3.0" on a 32-Bit OS] or you could just export it to Excel and do fancy graphs!
And it has the most cheapest CD EVER!The stupid surface that the data is stored on flaked off when I pulled it from the sleeve! It still works, and I could always just download the drivers off the net.
If I had to give this an subjective score I would give it a 10 of 10.
Very well made multimeter but the Software and accessories are cheap. But they all work perfectly.

It's not on the same field as a high end Fluke Multi-meter, but at it's at the top of the prosumer/enterprise level, it's a very very good buy.
