Keysight DMM - Yay or nay?

@blackdog thanks for reporting back. Awesome that you have all those meters and can provide such a nice comparison, altough this makes my life a *lot* harder now. I really do like the Keithley and its features, but I'm really struggling with myself if I can/want to accept the touch screen. To make things even harder I also stumbled across the Keithley DAQ6510 which now also entered the ring of contenders, unfortunately it is also touch-controlled.

At least the GDM9060 seems to use a comparable SD ADC chip to the Sigilent.

There is also a Teledyn (T3DMM6-5), that seems to be essetially the same as the Sigilent - possibly an OEM build.

Correct, no rear inputs on SDM3065X unless you get the 16ch scanner card but these have limitations for voltage and current.

@Kleinstein, @tautech Yes you're right the Siglent doesn't seem to have rear terminals, good point. Also the T3DMM6-5 really looks like a rebranded Siglent, it seems to be much more expensive though (according to a quick google shopping search).

blackdog:
Hi, Traceless,

You're welcome, I also have two Tektronics DMM4050 which are similar to the Fluke versions.

Of these I can say that at the 10V DC range they are also very stable.
They were last calibrated about seven years ago and the deviation is now about 4PPM at the 10V range at normal room temperature.

I don't think I would buy this model (Fluke/TEK) now. don't get me wrong, these are very good measuring instruments, but the price... silly Fluke.
One negative point is the input sockets on the front, on one of my two meters I have already had to repair it.
The machanic design of the connection bushings is a big Marketing mistake.
I am very careful with my measuring instruments but it still breaks down.
Soon, on the second meter, I will also redo the soldering of the input bushings.

Software for logging is also not widely available from the Fluke/TEK meters, that is also a consideration when weighing.

The two TEK meters are my workhorses, so don't think now that I don't value them. :-)

Kind regards,
Bram

@mawyatt to rule out that blackdog just had very bad luck with his KS meters, did you observe similar auto-cal issues with yours compared to the DMM6500.

Also since both of you @mawyatt and @blackdock have access to a DMM6500, can you by chance tell if a) I can ignore the touch screen and access all functions with the buttons next to the display and b) if the touch screen can be operated with gloves like this?
