The nominal U.S.A. voltage is 120. Code usually requires no more than a 3% drop due to conductor runs, but that is fixed and should not cause "fluctuations" if the load is constant. I was wondering why the nominal voltage has migrated upward since the early 1900s.
The range is usually set by your power company, It fluctuates based on how long the service drop is, and conductor size. I believe the official target is 110 v +/- 5%
I wish I had looked at the specs more closely, got me a 8845A, but now I cant measure temperature. Would even trade my 8845A with some money on top to get your 8846A.
I love your technical videos - thank you! Has the LAN connection feature on this meter become useful in the last two years since the video? Is there now some Fluke software available that uses the connection?
this precision is used to see deviation cause to the heat, seebeck effect, noise added on line, and any changement on the signal. The high accuracy is used to understand a time ratio, including the pourcentage of deviation according to the signal changement measure. This is a mainly scientific meter, sometime used to see changement, more than to measure a signal itself.
Has your nominal mains voltage changed over the years? In the U.S., voltage moved through 107, 110, 115, 117 and now 120, and you can see 125 volts at times. Who directs the changes and why? Note: Motors stuck at the 115/230-volt level to allow for voltage drop in the feeding conductors.
Just a guess but maybe a trend to avoid brownout level voltages on appliances and electric motors. Most motors seem to take 10% over voltage easily a 10% under voltage is a another story probably utilities wishing to avoid equipment brownout voltage damage claims.
I'm using an 8845A to read AC and DC voltages and currents on my machine. I'm noticing that when I try to read AC current it takes a while for the signal to stabilize on a value (approx 5 sec or so). I'm using this in a production line, so I'm trying to cut down on wasted time. I guess it is sampling values so that it can determine the rms number, but when I take my handheld fluke 115 in series with it, it responds much faster. Any suggestions? or is this as good as it is going to get? AC voltage, DC voltage, and DC current are awesome at around a 1 sec response time. Just thought I would get your opinion on it. Thanks, Range = 2 amps Resolution = 0.0001 amps Bandwidth = 20 Hz

I really appreciate your opinions on the trend plotting. Your video was the only one I could find that went over that feature well. Thanks!
Interesting, our mains voltage has "remained" at 220v as far as I know but that of course fluctuates depending on conductor run and loads.
They given it to me for some of the work I've done for them....so not quite for free ;-). Cheers, Martin.
I think the lighting issues was do to the frame rate of the camera and the frequency of the LED lights....I will try to resolve. Thanks.

My pleasure.
Great informative review thank you! Looking at getting one of these.

In the Netherlands it went from 220 to 230 (EU standard)... (and waaaay back it was 127v)
400V between phases and 400V / sqrt(3) ~230V between phase and neutral/ground. It's easy to remember.

Looks like it's cold in the workshop with that fleece zipped up...
Nice review - I'll pass on buying a second hand fluke 8846A, Ta.
pls show,, ac v and ac mv... from 50 hz to 10 000 hz or so... low ac voltages
Well done !! Thanks
Would you pls make review how to do fout point resistance test for solar cell pls
Very informative, Thank you
Hi, Thanks for review. Can you please help to share the website regarding the ethernet connection as I am having a big troubles with that
Excuse me, I have this device, but I suffer from high noise in the current measurements. How can I get rid of it? please
what's the difference between 0,999 V or 0,99883527297 V
In which field of electronic is such precision required ?
yes, the test tools are electronics too, how do you think you get to read the 0.999 accurately?
this precision is used to see deviation cause to the heat, seebeck effect, noise added on line, and any changement on the signal. The high accuracy is used to understand a time ratio, including the pourcentage of deviation according to the signal changement measure. This is a mainly scientific meter, sometime used to see changement, more than to measure a signal itself.
Is it possible to data log both current and voltage at the same time with this multimeter and then output to a csv file to analyse in a spreadsheet?

hmm, seems like a very basic multimeter compared to the 6.5 Keysight, would you say so?
What is the bias voltage in this device?
hello, is there any button to switch between LOCAL and REMOTE modes on Fluke 8846a?
What reference voltage board is that? Are there ones that also do reference resistance too? I need one for an old Fluke 37 I have. Thanks.
That looks more like a stroboscopic effect from fluorescent lights to me.
Does this Fluke come with Software, specifically i want to graph. even if transfer data in .cvs format, i could always create a graph in excel?

you got a ground loop. 7:00
You said "Comtest prodivded" you with the meter. Does that mean free?
Hi
Can you tell us in which contery is maded?
ut 61e
Wow man, did you get the money to buy this from your youtube channel ? :)
If Then I Switch On the Fluke 8845A Digital Multimeter Then Only Received Message INITALIZING show not on please confirm This is Start On
i see video effect sorry i m new to this whole video thing
