Exactly that, you could buy a cheaper Peaktech and get the same features. Normal Wire Wrap Resistors as Shunts? For 700$? come on! even the HF branded relays are realy shitty Or if you need it: the most bang for the bug gives you Keithley DMM6500.

[@asm_nop]

@@LazyTurtle1988 Not much? Don't have an exact breakdown but I'm tempted to make a guess around $200-300 given the large quantities they manufacture in. The ASIC would have been expensive up-front, but costs a couple dollars per unit after that.

@8:36: 495 SQ is a test coupon. This looks like a comb pattern SIR test coupon. SIR= Surface Insulation Resistance. Perhaps to guarantee that the surface treatment/s could withstand 600V (as shown somewhere else in your breakdown).

[@rustyosgood5667]

In an SIR test, the test voltage is usually north of 100V and 10^-8 or 10^-9 (I forget the IPC standard) ohms is considered a PASS.

[@EEVblog]

Could be. But in that case wouldn't the "surface treatment" include the solder mask?

[@rustyosgood5667]

@@EEVblog Not for the IPC version of the test. The comb is exposed. A pure guess on my part. I have never seen such things on a commercial production PCB. In the IPC (SIR) test structure, the board is meant to test certain (conformal coatings, fluxes, etc... type) treatments, yet this board doesn't seem to have any. Maybe they have a "Ruggedized" version that is coated and use the same PCB in both designs. Test structures that are meant to test the PCB features (as they relate to the manufacturing of the PCB itself) are typically on the outside (keep-out or tooling) portion of the panel. These coupons are added as a means for PCB process controls for signal integrity and other such characteristics. If we really had to know the Answer, My friend "Julie" over at Keysight might know what's up. Let me ping her and see if she can shed some ight!

[@tHaH4x0r]

The nice thing about 'old fashioned' instrument form factors is that you can easily stack them, not so easy to do with these without shelving. Screen is nice and large though. Also, the top component at 17:54 is not a LM393, but a TL072 (jfet opamp). Surprising to see so many jelly bean components in there, should make it a breeze to fix it if it breaks down for whatever reason. I suppose all the magic is of course in the ASIC. Instead of a full review, it would be interesting to see it compared to other multimeters in the price range. Since this is supposed to be about 720 euro, it has to go up against the rigol dm3068 and siglent sdm3065x, which are both 6.5 digits (0.0015% instead of 0.015% accuracy) and the latter also has plotting. Of course for 200 euro more you also have the venerable 34450A, although it doesn't seem to offer anything special for the extra money.

Not a fan of the form factor at all. If I want a bench multimeter I usually want 1 or 2 of them stacked with a PSU or 2 and maybe a function generator. Not sure the large screen adds enough value. Even in a university/school setting I'd prefer the standard format for the usual experiments you do there and the giant display is not exactly neccessary unless you use it show off a measurement in front of the class, but then you are better off with just a remote readout you can show on the beamer anyway, The screen seems kinda pointless, especially if you don't even use it to display a trend/trace.

[@BlackEpyon]

The Riden RD6006 power supply I bought (after seeing it here on EEVBlog) has a graph feature, which I found to be quite handy when eyeballing current load without using an expensive monitoring setup. Something like that on a bench-top multimeter, I could see using. But my eyesight isn't bad enough to need a 6" display for 5-1/2 digits.

Several people here have said they don't like these new shallow-depth bench instruments because they can't be stacked. It would be great if these units had the top shaped to allow stacking, maybe even a way to lock them together. Manufacturers: feel free to steal this idea.

[@todayonthebench]

The soldering on the through hole components is frankly a bit poor. There is little to no solder flow through on any of them. Either they run the boards too quickly through the wave soldering machine, or they are doing poor hand soldering. Neither one is really excusable to be fair. In regards to linear supplies vs switching supplies. It really depends on both the supply and the environment one runs it in. Linear ones tends to just let through all mains noise, one can filter out a fair bit, but most linear supplies don't even make an attempt.... Not to mention the nice ticking from the charging behavior from the rectification into one's caps. Switch mode supplies tend to always have input filtering for EMI reasons, same story for output filtering. This largely eliminates mains noise, leaving the largely known switching noise of the supply left, something that isn't all too hard to filter out. (a pair of caps, and chokes goes a long way.) Though, test equipment should have fairly excellent mains input filtering to ensure that they do not interfere with the operation of other equipment, nor is easily effected by any mains noise that happens to be there. Funnily enough, this is part of the CE requirements that a device shouldn't interfere with other equipment expected in the same environment, though, it also requires the opposite too, a device should be built to not be hampered by stuff that is expected in the same electrical environment. (Directive 2014/30/EU on the harmonization of the laws of the member states relating to electromagnetic compatibility, Chapter 1, Article 2, part (d). but I suggest reading the whole thing, not just the short segment outlining these two points.) So if one operates the device in a noisy mains environment, then an SMPS supply can actually be the better choice. And all one needs to swamp the mains with noise is 1 poorly built mains adapter....

[@rustyosgood5667]

Much of the spacing and even the buried traces seem to be Safety features. If you assume the surface is contaminated (wet) then the inner board spacing lines up in terms of insulation.

Sure, but good practice dictates not running them under lower voltage parts unless you have no choice.

The trend-plotting feature is extremely handy and probably saved me many hours if I did not have it at hand, especially when plotting current measurements.

IMO, the ISL21090 is not that good of a chip unless you really want good initial accuracy. I've personally worked with AD421B chips and they have better 0.1 to 10Hz noise and the temperature coefficient is 3 ppm max, 1 ppm typical. I don't know why Keysight went with such a voltage reference unless they don't want to calibrate the instrument afterwards which is highly unlikely. Although, the ISL21090 has better long-term stability which could have been the motive. I'm not a fanboy but I prefer references from Linear Technology / Analog Devices, especially the LTC6655BHLS8 which isn't that much more expensive and has far superior specs like much lower noise, 1 ppm typical and 2 ppm max temperature coefficient, and better long term stability.

Probably a silly question here, [ been years away from electronics ], but the remark about the transformer implies that they're not used anymore , is that correct ? Thanks , Kieron

[@marcdavis7583]

the mains transformer is a relic from old linear power supplies, which are typically 40-50% power efficient but are quiet. For the past 30 years, most electronics have used switching power supplies (they convert the mains to a rectified DC voltage, then chop it at high frequency using smaller magnetics, with lower losses and much higher efficiency, you can get 95%+ now). There are issues with switching power supplies - they need more components, can be more expensive but generate more noise. So going back to a linear supply with transformer is OK in some applications, especially measurement where you don't need a lot of power and don't want any induced noise.

What's the point of the massive screen if you can't use it for any visuals. May as well slap on a VFD for all the info they give you

[@amrishhirani6096]

Easy and strong meter Thank you 👍

[@ESS1024]

Hmm, I thought that rust on the metal frame edges is patented by Siglent.

Hi Dave. You should definately do a full review on all the new givaway gear. Thet would keep the viewers and the magical Dumpster fairy happy.

It's slow,it's ugly and overpriced

[@allansmith6140]

I have a few nice bench multimeters, truth be told I hardly EVER use any of them, reason being they are too slow to set up as they are all button based. I could think of a thousand other things that would be more useful on a bench than a bench multimeter. This thing though takes the cake, yes it is UGLY, looks cheap, crap performance, and price is LOL.

David spell check your subtitles at 6:22

If they're putting a multimeter in a bench chassis, the least they could do is to make the volume of the continuity beeper adjustable across a wide range, and also change the tone to a more pleasant frequency. It's not like there's a shortage of power or space for a decent speaker in this thing. Why does it still have to screech like a dying cricket?

gonna get keithley.... edu prices went to usd900

What is that music in the background? EDIT: Ahh you are waiting on hold!

Most of the PCB design decisions that you declared as silly seemed to be justifiable IF one is obsessed with keeping creepage distances high*. I guess as your device gets dirtier and dirtier as dust builds up, the effectiveness of creepage is continually worsened, whereas the insulation withstanding voltage through a layer of solid fibreglass will never change, now matter how dirty the surface is. So if you want the device to withstand years of neglect, you do that by pushing creepage distances to the max while not really caring about clearance and distance-through-solid-material (whatever that's called). Whether this is actually good design though, I dunno. * For example, the relay coil-driving traces "pointlessly" diving down to an inner layer would have had a shorter creepage distance to the pad on the "hot" side of that big ass resistor if they were on the top layer.

I would still use it.

Seems like a good form factor for education. Get them out the cupboard.. use on a bench... put back. This is a different use case from being set up permanently on shelves at the back of a lab bench.

Would you talk about the renting of Tesla solar roof ? Money back, energy, charging electric car (Tesla of course 😃) ... Please Thanks a lot

[@robertbox5399]

This looks like a Chinese knock-off at Keysight prices. Look at that power button!

[@codplayer808fly]

Hey Dave, is it worth to get a IEEE membership?

[@LogiForce86]

Give aways... I always miss them and/or just never win them. 😢

[@Salamekleikum]

It gives me a feeling like some aliexpress garbage... but that price...
