Ok it's not working again....

Unless I'm missing something obvious.

I have a 56K resistor with probes attached either side.  First I'm measuring with a brilliant cheap multimeter the Owen B35T+. It measures the resistor at 56K5 which is confirmed using using Keithley 2100.  Then I haven't changed anything at all but simply moved the probes from the Owen to the 121GW.  The 121GW measures the value as...... well it doesn't even recognise there is a value.  I then put the probes back into the Owen and it is measuring the same.  All I get out of the 121GW is OF.L. Not good for a meter costing 10-15 times the amount. 


I have a similar issue on Ohms range. In my case is the rotary switch. If it is not centered exactly, it doesn't behave correctly.

Yes after it worked that first time it now works every time (I will have to start using it more to make sure it doesn’t happen again before the warranty is up) I bought this 2-3 months ago but as I have a couple of Philips/fluke and a Keighley bench meter on my bench it doesn’t get used much (twice). I’m currently scrabbling around on the floor trying to rewire a cab with speakers that don’t belong in it! I was getting more and more annoyed :-) it’s working now and I can get back to my nice soothing valve amplifiers.......

Fire walker,

I think it was just that the button was stiff from new or not seated right. It’s working fine now and all the other buttons SEEM to be fine. I’ve only used it once before. I can’t use it as my main DDM as I build valve amplifiers and I’m messing with voltages higher than 500v which it didn’t want to measure (no doubt there will be a way to measure them and I’ll have to check the destruction book to see). I’ve not spent any real time with it. I bought it on a whim when I got a refund for a camera for my bench scope.

Not my go to meter as it makes me work hard to get results but I can report it spent a night in torrential rain and after a drying session appears to be fine.

I've been using mine often as an auto electrician, but I don't work flat out so it's not used every day. The voltage accuracy is brilliant.

It happily measures micro volts (after the decimal), so when power is flowing across a fuse, I can approximate the current draw from the voltage drop. Fuses act like a current shunt, but the reading is very small and changes for each fuse size.
Hoping for a chance to use bluetooth or logging on a job. It works well, given it uses BLE to save energy. That gives it a refresh rate slower than the LCD, but it's fast enough for many things.
I get slightly different diode voltage readings between 3v and 15v. For example, an IR diode reads 1.038v (3v) or 1.131v (15v). To be fair, accuracy isn't specified for diodes. Maybe the PTC affects the reading too much.

I'm glad that this meter has worked well for me. With firmware v2.04, it's given me no problems and I like it as my main meter

lol, yep fix all problems by burning the error report.

have it actually ever happened before here on eevblog a whole thread being nuked.

That's really strange.   Is the plan to merge those posts into this thread or is the idea to try and erase the history?

That wouldn't make any sense -  this thread (EEVBlog 121GW Discussion thread) was started after the KS meters had been delivered - and is more or less a continuation of this old thread: https://www.eevblog.com/forum/testgear/new-eevblog-branded-multimeter-coming/.

The now missing issues thread was intended for reporting specific issues - sure there was some overlapping between the threads - but for the most part they served their purpose - and a possibility to report issues with less chance of it drowning in the general discussion around the meter.

I could also just have said - if someone thought there were to be too many 121gw threads - then just lock the one(s) deemed redundant.

I don't think there was any confusion about the purpose of the thread.  Deleting it makes little sense to me.

It doesn't look like Dave or Simon been online since the thread disappeared. When they get back hopefully they can provide some info on wtf happened.

IMHO the 121GW never lived up to the pre KickStarter hype or the potential of the design. Major hardware problems with the selector switch and then auto-ranging times, etc, with the firmware, set the scene for a troubled launch.

I bought into the KickStater event knowing full well the V1.0 could be a lemon, but love EEVBlog and supported Dave in the venture. Well the meter is usuable and a good size for limited bench space, so for basic multimeter functions it gets used. I'm surprised Dave is closing off forum discussion on the meter's issues and would like very much to hear Dave's reasons for doing it.

I personally would not buy another test instrument from Dave for the simple reason that I think customer support is not at a professional level and many other wholesaler/retailers do a much better job. Stick with what you do well is always a good mantra to follow.

Dave is really good at critically and objectively evaluating test instruments and EEVBlog teardowns and forums are the best in class.

That is not certain.

All we know is that the thread is no longer available.  There could be other reasons.

I would like to have a specific response before venturing any further down that path.

 :o  :scared:
I did delete a new thread the other day that someone started that was a duplicate of a post in the Isssues thread, but that was it, I did not deliberate remove the Issues thread.
It's possible I deleted the wrong thing  :palm: , I need to investigate....

Yep, it was deleted  :(
I can see the entire thread in the deleted posts section but the Restore Topic function doesn't seem to be working, I have no idea why. It spins the wheels for a few second and goes back the list as if it worked, but it's still in the deleted section.
So I'm currently at a loss as to how to get this back  >:(

Maybe you and another moderator saw the new similar post. One deleted the correct and the other the wrong one...

Yep, I suspect that's what happened.
Normally not a problem, just hit Restore Topic and it's fixed.

Well, the data is still around then.  It's just going to be a matter of getting links and pointers and whatever other elements of the structure back to normal - but doing this manually requires a full understanding of how SMF does this.  These details can become convoluted, especially on software that's been around for a while and has had lots of revisions.

I won't pretend to know SMF this well, but unless an SMF process can be found, I can see Gnif possibly getting involved.

It might be an easy fix - or it might not.  Be patient people.

Apparently it's a bug in SMF when threads get too long, they can't be restored.
But Gnif worked his magic on the database and it's back!  :clap:

Manually tweaking the database is his preferred method for everything, he's a nerd  ;D
