Now if i could only fix my cheap Gordak soldering iron to not run the heater full blast every time i'm testing a RF amp lol.

Ran into same problem with meters that were sensitive. This meter does have that internal capacitor that you can use for AC. Just not a great setup having to use it.

If they are not asking you to buy an analog meter, I would hold off. Just use what they provide you.

I doubt you would find a fast enough mechanical protection system that would save the meter during these tests. Most of the event is over in 100us.

Why waste time double posting? Oh right, analog meters.

@@joesmith-je3tq sorry I didn’t mean to bug you. Just didn’t know if you’d see it, and I’m half brain dead these days😬🤷‍♂️😁

Why do they continue to use unfilled glass ...

Most are Vishay low temp co, 0.1%. Less than 1ohm and the 100M ,1G are Ohmite. Caps are all film or ceramic.

Certainly more robust than it was and no more glass fuse. It slams pretty good in the forward direction as well. I thought about increasing the size of the dampening cap but would end up giving up some of the response. It would be fun to try and protect a high end analog meter. If I were to design a modern analog meter it would be a hybrid. None of this low impedance rubbish. lol.

LOL you would make a digital/analog dual display meter, a fet op amp tapped on to the output of the resistor divider to drive the analog meter, the best of both worlds :-D

Right. Or maybe a stepper motor meter. Than again, I haven't used an analog meter in I would guess over 30 years. Talk about beating a dead horse...

Hey, your the one that suggested modding an analog meter, i was just commenting back, stick to the digitals.

Well it was "If I were to design..." I'm sure they have their place but it escapes me what it is. The few times I would have liked the visual effect, I can now get with the Brymen.

What does the waveform look like? Is that 6V peak, p-p, what? What sort of wave shape? Is there any DC bias to it? Do you have a scope that you could provide a screen shot? I could then run a test for you with the meters I have available including this one.

I have an Oscilloscope, but only analog one with 10mhz bandwidth. waveform would be a triangular , symmetrical peak around 22V from the bottom, 20us at base, followed by 40us of flat line.Falling edge of the triangular peak is filled in at the bottom and transition to flat line is smooth on that side, raising edge and peak are sharp at corners. I didn't check for dc bias, but my ut139c show the frequency of this waveform, and it wouldn't want to do it with a waveform that does not cross trough 0. Or i just don't know how to use it :] my old ut201 (non rms) show about 5,15V at ac range, ut139c true rms shows 0,0006V (out of bandwidth), service manual of my tv cals for measurment with hp 3403c and rms voltage value of 6,3V at 700mA (ac bad 10V scale) And since i replaced the crt and that is the only voltage i have problem determining value of i am a little cautious about it. I was thinking about making an opamp buffer powered from 3 9V batterys in series. a 500k pot to set ground bias and 2 3 meg resistors, one for input and one as a bias output for the floating ground edit if i read schematic corectly, it is dc bias at 53V from the chasis ground, but it is driven from its own winding of flyback transformer in closed loop.

20us + 40us would be 16.67KHz. Is this just the error in your measurement? Is the rise and fall of the triangle 10us?

Saw your post on EEVblog with the scope shot. I'll post what find in your thread. It will take me some time to put a test together.

thanks for your help, as for the the scope measurment, it might not by accurate, my scope wasn't calibrated on a timebase since i got it , and it is about 30 years old. In my post on eevblog, the waveform is verticaly fliped i was measuring it with both scope and tv floating with no earth reference.

It's a good idea to learn to use a an analog meter and read an analog clock. I have not used an analog multi-meter I would say for at least 30 years.

If you posted a distasteful comment, YT never notified me of it. It could have been bad enough that YT filtered it. The videos are not really suited for the kids.

I just said something along the lines of you being jealous of eev success. I take it back your clearly more knowledgeable then Dave in this area

Trust there is worse , there is backdoor sold Chinese Chinese copy , with half component removed , like continuity check , buzzer and LED , gone with the wind , thats my version labeled as TRN , but tis ok , im using it as ammeter/voltmeter for my DIY power supply , tough me more then anything , striped it down to the gauge and reused it as volt amp meter for my DIY power supply , something i couldn't do if it was original expensive version , dont have that much cash to destroy expensive stuff .
