Someone better word up the Fluke humble showman in that youtube video >
youtube.com/watch?v=OEoazQ1zuUM&feature=youtu.be&t=325that there is NO FUSE inside a Fluke 114, and no current inputs,
like hey, I own one for that reason (besides being a decent no frills meter) and have taken it apart to see what I paid for, and customary check for possible assembly-line dumbassery
therefore NO -quote-
'expensive fuse' exists in that 114 meter that he harps about, to protect the meter or operator in the event of a bad hair day turning the selector knob the way he did whilst applying 660 volts AC
He could have at least opened the 114 like he did the cremated red cheapie meter to show us the ummm... 'invisible expensive fuse'
Double Dumbass and Darwin Award candidate points for not wearing gloves or eye-wear for his own anti-Murphy precaution handling the unholstered Fluke,
nor supplying eye-wear for the audience/bystanders, thus setting a proper SAFETY example.
and aren't fuses usually in the current path on most meters anyway, not volts and ohms
and what happens if there's moisture ingress, or debris from a drop, inside the meter and the operator plays 'spin the dial' with power applied ?
Surely Fluke can do better than this halfassed product promo
FWIW our host Dave Jones has a dissected Fluke 114 video EEVblog #597 here >
youtube.com/watch?v=iFyEqcVpKLISkip to about 8.45 minutes where he gets to the main board...notice no 'expensive fuse' or gold plated fuse holder to be seen
Thanks to MJ Lorton for posting the video and useful summary at the end
EDIT: It's a Fluke 113 the Fluke rep is using in the Youtube video
youtube.com/watch?v=OEoazQ1zuUM&feature=youtu.be&t=325 which is a basic 114 style idiot proof meter that auto selects between modes
It too has NO FUSE, either 'expensive' nor cheap glass
The 113 is too 'auto' for my liking, the fixed 'auto' Low Z can be a pita when prodding into RCD/GFCI circuits to confirm 240v or 120v etc, because it trips them!
You would think Fluke would try and trash an 87V with 'spin the dial' games at 660VAC
versus a red manual range cheapie
guaranteed to issue magic smoke and fireworks,
instead they selected a Fluke with 3 position dial with auto select modes... basically a 'meter and leads' version of a a typical electricians dual wand voltage/continuity tester If their meters survive russian roulette 'spin the dial' games at high voltages, then it's some form of protection in the front end circuit/s, saving the meter,
not 'expensive' fuses in the current path AFAIK
and it's anyones guess how many times and for how long, and under what conditions any meter can survive such abuse,
or how much of it's accuracy and reliability compromised
FWIW the only meter documentation I've ever seen suggesting -dial changes- is starting at the highest relevant manual range,
and selecting a lower range in the same mode if required for better accuracy and / or needle scale depending on the type of meter
