When you are an industrial electrician Fluke is the go to instrument. I've used a Fluke multimeter for a couple of decades now and it's been the same meter
I’d be interested to see how the readings of this instrument compare to your less portable lab equipment. Also it would be cool to see how high of a frequency it can handle.
For those who are looking at repairing one of these, Fluke will repair any current model unit for free.... I've bought several broken current model Flukes and sent them in for repair. They even sent them back with new batteries and a calibration certificate!
Wow, what a great find! I used to use its big brother, the Fluke 434 to check the operation of 80 KW UPS systems - really amazing test equipment in a small package.
Please consider doing some inrush current research :) Especially with big SMPS which are pain in the ass to use and trip breakers. Any way of limiting inrush current even more apart from built-in limiters in them? Especially when they share the same power strip and are powered on at the same time
Maybe there is an inrush current- the heater coil should have lower resistance at room temp compared to when it heats up. In fact, I can’t see how there could not be an inrush current. Try it and let us know
@3:12 would you know what the original value of these 4 resistors in a row in the input path are? I've got a 345 that had battery leakage and these four resistors were completely caked in. cleaned it as good as I could but meter overreads 10V consistently, I think due to leakage because of remaining battery gunk?
Were you powering that heater from from the public AC supply, or from an AC PSU? The waveforms looked much more sinusoidal than I have ever seen on the UK mains!
Thanks for this vedio. i have agilent e4416a rf power meter. the stand by indicator light is on but when I press the on button nothing happens can you help me. knowing that the battery measures 2.9v and the voltages 12v -12v and 5v exist
An interesting video. I think many products are made with the wrong type of plastic. A portable device like this should be capable of being dropped. I wonder if it was over tightened in manufacture and broke when the screw was turned. It has many features but extremely expensive.
Still $320 on ebay ;-) LEM Ultrastab are far cheaper and much more accurate, bought a bunch of them for $30 to calibrate my 400A TIG welder, total overkill, but worked nicely. DC to few 100kHz bandwidth, so you can watch welder current waveforms on scope, with like 50ppm accuracy ;-D
Yeah, funny how some people get these kinds of "repairs" and all I get from ebay stuff listet as "does not react to keyboard input" is things where the internal lithium battery exploded and ate away all the expensive digitizer board...
It would be interesting to see the results when driving a cheap switching power supply (wall wart), or the output of an inexpensive UPS or generator.
Fun video Shahriar! Thanks for taking the time to post, It's nice to see more video's from you.
That's one lucky score, you should do the lottery more often.
You are videos are always quite amazing !!
Oh wow what an endlessly useful looking tool
Ill keep an eye out for broken units on ebay
as an embedded dev who regards RF circuits as magic, it's gratifying to see an RF expert impressed by a latching shift register for button input 😜
I wouldn't say I am impressed by it. I was just describing how it works. :)
@@Thesignalpath it's nice to hear these details, not all of us have seen everything, and there's so many ways to solve digital problems
Nice catch!.....i quite like it, lots of great features.

Great video,Louis
The keyboard with a shift register is the same way Nintendo handled controllers on the NES and SNES

Great tip, thank you!

Nice quick fix. They could have included a bit of scholastic for the money. Meter has some good information and a nice score.
It's best test to come is within the jefferie's tube.
Nice deal with simple lucky repair! 👍😉
Hello .. A very very useful and well explained video... Best regards....!!

A 100W tungsten filament bulb in series and a relay that shorts out the bulb after a few seconds.
@@simontay4851 yeah, I always thought that such thing should be an internal part of these SMPS'es ;)
Have you sent the date to 2021. thanks for sharing.
Damn! Yes, it seems 2021 took only a few months to pass by...
TNP inflating prices on secondhand market :). Nice work.
Great work 👌.
Congratulations with that fancy fluk
Hook it up ton a induction motor pump (ie pool pump) with and without load. Spoiler alert: Current does a wobbly

He did it again. Last time i bought something like this, the processor was fried and the firmware not available of course.

Update about this lazy question: All are 220kOhm, I replaced the 4 contaminated ones and the device works perfectly now!

It’s from an AC supply.
i bet the seller is gouging his eyes out right now :))

wonder if it has hall sensor for current measurement , what's the chip ?
An interesting video.

As you usually say "here you are nothing special " it is not 50 GHz Bandwidth instrument , BUT it can measure 2000A😁😁😀
👍.
Does it measure DC current as well? Hall sensor based?
Yes.
lucky lucky find
Wow ! only Fluke can get away with these prices, great find though...cheers.
No replacement fuse is scary!
not PO, PQ (Power Quality)
Yes! Misspoke.
🙏👍🙏
"The Industry Standard", "Ultra Rugged", "Ultra Dependable", Mighty Fluke couldn't spend $0.10 for some glue ????
Nice score.... you have the date set to 2021 🙂
Thanks! Fixed. :)
That's NES controller keyboard technology.
I am sure this unit performs well, but the case looks like junk. I think they are selling a good $100 meter for three grand.
I’m the industry standard I can charge any price
Are you shure, battery CR2032 is rechargeble?
It is not a "CR" prefix. It is a different part number. It is VL2020.
Still $320 on ebay ;-)

I was surprised that the frequency resolution wasn't better for $3k
