Nice review Scott, and good spot on the weird range switch errors. 👍 Loving the continuity sensitivity on this one.
But those 2mm(ish) jacks... noooo!
Try this mate whenever you need probes to stay in 4mm jacks.. Put a couple of cm's of cocktail stick in each jack, then push the probe in. It'll be retained nicely. Works a treat 👍
Cheers mate

I'm too old school for one of these knobless smartphone thingies, but it looks neat!! Anyway for me any meter that does not use standard 4mm jacks at standard spacing is unacceptable.

Really liking that calibrator, so purposeful in design.

Nice review! Thanks! Also sprach Zarathustra for the screen pull ;-)

It's a nice meter, at least the one you have is pretty accurate, got to be careful though they'll send you an accurate one then send out ones that aren't too accurate. Now I wonder how it would do in cold weather like being outside working on something in cold weather. 🤔 Great review 👍🏼👍🏼

The "problem" with calibrators is that they themselves must be calibrated to a standard and any test carried out are only relevant if the NEXT calibration is carried out and the equipment is certified. I believe Siglent (formerly HP) has a gold standard mobile calibration vehicle that does the rounds here in Oz that cost better than a million bucks to fit out. Why? Because there's bloody good money to be had and it's basically compulsory if one wants to remain in the game be it calibrating industry equipment or simply using certified equipment fro ones own business.
The equipment in that Siglent vehicle is taken to a calibration centre in the US to be calibrated.
Looking hard at your Datron 4700 that you picked up off eBay and used in reviews, I saw no calibration sticker. That's the problem isn't it. It's a rabbit hole that we have to go down OR decide to wing it. If one isn't calibrating other equipment it's hard to justify say in a smallish repair business such as yours. I mean, no one cares but you.
Finally, I would like to see you or someone do a video on compliance/calibration. It's one hellova fascinating aspect of test equipment.

Nice review - hate the test leads! The cross-coloring and non-standard size is just wrong. The obvious choice for screen peeling would be "The Stripper" by David Rose - not sure about the copyright though. Thanks for reviewing all these "entry level" meters Scott.

I like the option of USB charging. The non standard banana plugs wouldn’t be acceptable for my main bench meter but perhaps as a standby meter maybe. It look a bit different to sit comfortably with my expectations etc. The probe colours are just stupid. Thanks for the review regarding chris

[tigrafrog]

Thank you for review - I'm starting to looking for second DMM.
Exactly as Electric Car - looks slick, rechargeable, but completely useless for everyday usage. Also, exactly as Electric car, will not work when -30 C outside (today on my location). Nice looking toy.

[showkothossen]

Beautiful meter. It’s available in Dhaka? How much?

[Chris_Grossman]

The non-standard lead jacks are unacceptable.
Why didn't you use alligator clips to connect to the leads?

[andymouse]

Those weird leads are a deal breaker for me....cheers.

[captiveimage]

Too many compromises for this to be of any interest to me, even as a chuck-it-in-the-toolbox meter. Slow update, low resolution, lack of accuracy on 'auto' and those leads... Horrible! For not much more dosh, a Fluke 101 would be a better, more useful, more reliable tool.

On the positive side I do like the recharge off usb option, and the one line, non-contact AC beeper is pretty cool.

I really enjoy your reviews though, and your screen peel's are hilarious. 🤣🤣🤣

So just say it's a junk don't buy it
