My only gripe is the location of the symbol. Like it is right now, it strongly implies it refers to the primary (lower, bigger) value instead of the secondary, top one.

I noticed this too and don't like it. While the meaning is understandable, it does grate on you.

He needs to ask?

For what outside customization someone whats if any.  No electronic ideas.  At a min he could sell autographed ones.

Yes, gold plating or a solid gold body makes so much sense in a meter designed to test mains voltages...  :-DD

In order to be sellable on the open market, it would have to be put through the whole testing process separately from the standard meter, and would fail on items like double insulation. Creepage and clearance issues would be a swine. It could only ever be sold as an ornament, not something that is intended to be used around electricity.

Cat III 300V is tested to 4kV  IV is 6kV. I wouldn't want to be holding that meter...

Dave, why did you call it the 121GW?

Any idea when (roughly) it will be available?

if its basic accuracy can be on par with F289 or U1253B

It's not.
Deliberately a lower accuracy to meet a lower price point

Will this meter be more accurate than the BM235 ?
Do you have any idea when it will be available for purchase ?

I'm in the market for a new multimeter and just happened to stumble upon this thread. I'm super excited about it and will hold out until I hear more info about this meter.

Take a look a look at video "EEVblog #966 – CPM700 Counter Surveillance Monitor Repair" (about 5:15 in) to get a peek at one of the prototypes...

Did the issue of the "m
                                  V" display get sorted out?

The LCD is not changing, we have more important things to worry about.

I can't help thinking you would make as much money with far less potential grief just selling another batch of rulers.

There's no challenge in that.

The 121GW is very much worth the effort!

Indeed, it's fun to have been part of the process.
The uRuler is coming as well, just have to think of a few more things to add.

More centimeters?

Something that will be a world first in rulers

Add WIFI, so it can convert between metric and imperial using some cloud service. :horse:

Put the numbers on an LCD, the base model will only show centimeters, when you need millimeters you need to buy an additional license. :horse:

Sure, why not reveal a low-burden multimeter just after I order a uCurrent?  :P
At least this uCurrent will have a lot of experiences to share with me, as DHL seems to be giving it a long vacation in Europe  >:D

This is the full quoted text of the response from Dave to my enquiry.
The LCD is not changing, we have more important things to worry about.

That's a very direct, honest answer. Good on Dave for doing that.

Selectively editing words carelessly can change the meaning. I would possibly tolerate that sort of unctuous post if seemed other than totally self serving.

I must have missed something.    We know he was having some problems with the BT connection.  Not sure how saying I'm sure they will sort things out is self serving.   

Meter is looking sharp!  Hope the testing is going well

Actually, a few major issues still...


I couldn't help thinking of simpsons after I hear dave mention "it has bluetooth, 4 AA's instead of AAA, and two full size HRC".

I just got the prototype and the Bluetooth doesn't seem to connect on my android phone  :scared:

I was doing a little bit of google "research" on AFE (Analog Front Ends) and such for DMM's, and I came across this very interesting document from TI:
http://www.ti.com/lit/ug/tidubv5a/tidubv5a.pdf

Wireless IoT, Bluetooth® low energy, 4½ Digit, 100-kHz
True RMS Digital Multimeter Reference Design

Features
• Basic DMM Measurement Modes:
– Voltage: 50 V, 5 V, 500 mV, and 50 mV
– Current: 50 mA and 500 µA
• 18-Bit, 400 kSPS, SAR ADC Enabling:
– 50,000 Display Count Resolution
– 1-µV / 10-nA resolution
– .05% DC Accuracy, 3% AC Accuracy at
100 kHz
• Wireless MCU Enabling BLE for IoT Wireless
Communication
etc.


I wonder if this DMM (121GW) is built on any aspects of this "TIDA-01012" reference design at all? (50000 counts, bluetooth, etc)

If not, does anyone know of any DMM which IS built based on it? It sounds pretty cool, and interesting to me. I like the features, and although I haven't read the whole PDF document yet, it's making for some interesting reading.
