Secondary Bench DMM recommendation
« on: March 31, 2020, 07:25:46 pm »
I'm looking for another bench DMM to complement my Keithely DMM6500 (current or voltage measurment) so I can know how much power a device is consuming as well as taking other measurments while I assign the Keithley to more important measurments.

Not looking for something expensive and the Siglent DSM3045X caught my attention as it is around my budget (500$) with shipping and taxes.

No specific requirments in mind except that it must have a graphical display screen and display reliable and accurate readings.

The SDM3055 is also appealing but it is a bit over my budget when you factor in shipping costs + custom duties.

It would be nice if I could somehow connect both units to a computer and have a live power measurment on there but if that's not possible then I am ok with it.

Please let me know if you'd recommend other products as well.

How about buying a power supply which can show (log) the consumed power? Way more convenient and no burden voltage drop for the current measurement.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I shouldnt have said power consumption but instead power draw.

I am testing AC and DC loads so will need two DMMs for this kind of task as the power meter I would like to buy is too expensive (R&S®HMC8015 Power analyzer).

Gwinstek makes power analyser that seems decent and has normal price..

I thought it was only for AC power. I read the specifications and DC is also supported it seems (GPM-8213).

That changes everything. Will look into it thanks!
