I guess you'll finally be buying one these then Brumby!!!!!!!!!
Perhaps not? As you seem to know all Dave's intentions for this meter, both present and future, if you resist this bargain 20% off deal then maybe your holding off for a revised model?
My guess is that Dave has stock on his shelves that needs to be turned into cash. Stock on the shelf doesn't do anything but tie up capital. It needs to be sold and new stock ordered for any business to survive.
Correct. I talked about this on the Amp hour the other month. I have to buy a lot of meters in one hit, and it's a huge amount of money, the last lot (plus other things) practically wiped out the companies cash reserve. So much so that I had to stop paying myself wages.
Not surprising to anyone with half an idea of how small business is challenged on a daily basis. I don't have any secret communications, just common sense (sometimes ).
It's just a meter, there was some excitement because it was a kickstarter, but now it's a year and half later and it's now just another product in my store. That was inevitable.
I'm using 2.00 firmware at present and UEI have said we can release it, so expect it soon."
Fixes are still coming. I'm using 2.00 firmware at present and UEI have said we can release it, so expect it soon. Improvements are better and faster resistance and capacitance autoranging.
Could someone please share calibration data? I lost it while messing up with the meter and not all ranges I can calibrate (like I don't have a high-voltage source for AC, for example). I know results won't be perfect, but it's fine
After Dave's comments about reviving the toggle bot to repeat the switch life cycle testing, I offered to buy a couple of the new meters and run that test for them but no response and I have not heard anything else.
If I had a spare new thicker PCB meter to send you, I would.

Or people could just listen to The Amp Hour
Does anyone have any idea on how to source replacement probes?
Now, it seems that the "soufflé est retombé" as we say in French. I would like to be proven the opposite, but except a few apparitions of the multi-meter in some videos, enthusiasm seems to be gone, upgrades are no longer available, no more reaction from any Dave.
What "enthusiasm" do you want?
Want me to include an outro in every video plugging the meter?

"Low Z" is typically meant for "ghost voltage" on mains.
But wouldn't it make sense to allow it to be used for other things like testing batteries?
In most high impedance "ghost" mains voltage cases isn't one more interested in measuring the current anyway (measure with a few kohm R in series so no chance you blow a fuse somewhere)?
just use normal voltage range.
But wouldn't it make sense to allow it to be used for other things like testing batteries?Theoretically yes, but the current would be still pretty low for a battery. E.g. the Fluke 117 has ~3kOhm resitance in LoZ mode, so a 1.5V cell would cause a current of 500µA. That's probably not enough to be useful for battery testing.In most high impedance "ghost" mains voltage cases isn't one more interested in measuring the current anyway (measure with a few kohm R in series so no chance you blow a fuse somewhere)?
just use normal voltage range.Ghost voltages are created by capacitive coupling (no current flowing). With the typical multi MOhm resistance, you can measure voltages like e.g. 75V that seem to be dangerous. When measuring in LoZ mode, the current over the e.g. 3kOhm resistor is enough for the ghost voltage to disappear.
You think that if you put AC across a capacitor no current flows?
I thought we were all engineers in here.

LoZ is for AC and DC . When "engineering minds" work in real world will find many situations when a voltage in a circuit looks OK with a tipical high impedance multimeter , but it's not actually , because there is a fault and the circuit is just capacitive coupled or there is some high resistance conductive dirt somewhere ... For this is LoZ .
For example in a car circuit , you should check with LoZ or a light bulb if the fuses are OK , if not , a blown fuse can leave some conductive traces and you would be fooled with a normal multimeter .

You seem to be missing some basics here...
For the ghost voltage situation, putting a DMM with a 10M (or higher) input impedance across it is not going to load the voltage down a lot. You could easily measure 100VAC which might prompt you to start chasing down a fault that simply does not exist. The simple answer is to put an appropriate load across the measured points and then read off the voltage. Know your load and know your voltage means you know your current.
What is of most interest here is not the actual current that flows but the voltage you read when the circuit is under this load.
So why is it AC only on the 121GW ?
Most interest? Why? The rules and regulations about how much leakage is safe quote currents not voltages across some vaguely defined non linear load.
So why is it AC only on the 121GW ?
Why do you believe it is AC only?
My 121GW have no problems showing DC voltage in LowZ mode.
