I always sort of assumed the holders on the back of the DMM had 2 positions, one for storage and one so that you could hold the probe and the DMM in one hand and the other probe in your other when field checking. Not sure if this was intentional, but I've definitely used it like that before.
Hi, at 1:50 you measure the low current fuse resistance, the meter indicates 10.7M Ohms. That is not what a slow blow fuse should measure out to. Slow blow fuses do not have 10M Ohms resistance, I understand they are basically fast blow fuses with heatsinking to delay the wire fusing. At 4:13 you should be able to apply enough charge to the gate with most DMMs in Ohms mode. At 6:50 the tips storage in the back of the DMM, you can still leave the negative probe in the storage slot but protruding to help when you have to measure say a power board and don't have anywhere to secure the DMM. Use the DMM with the negative probe in the back, protruding out of the DMM, and use the DMM as the probe holder.👍👍👍 I have a pair of needle nose probes that each connect to a banana plug, they are great for pushing thorough conformal coating or tarnished copper tracks. E14 P/N 2917883 as an example.
Hi Good Informatics Video Thanks, Im from Bangalore City - South India, we do repair work on AV Equipment like LCD TV , projectors and AVR Amplifiers, I need to buy good DMM for my job, plz suggest us any good DMM model . Thank you.
I though youvwere going to show how to check out who's who in a bjt, emitter, base and collector with a dmm. the emitter and collector of the bc's are swapped in relation to the 2n's for example.
Blowing the fuse I've learned a long time ago but my friend at work keeps doing that so we changed almost 100's of them now and he still won't change the plugs back 🤣
Using the diode test to charge up the gate capacitance of a mosfet is pretty sketchy. Some DMM's can only output a little over 1V for the diode test. And lots of power mosfets have turn-on voltages around 10V. A better way is to use a power supply to apply your gate to source voltage, and just use the DMM to measure the channel resistance.
James's videos are concise, intelligent, thought provoking and entertaining. As always. Thanks for you work!
Thank you. Great video.
Great tip on SMD LED polarity checks!
This is your BEST video yet !! Thank you and may God bless you and your family.

TIL a new way to use the holders on the back of the DMM!
Great tips, thanks
This was definitely one of your more useful videos👍👍

Not sure why, but ohm mode didn't work with this meter for the FET. I tried several and none would get enough charge.

UNI-T 161E this one is the best for the price.

That DMM from video looks like a UNI-T OEM branded..

thanks for not supporting Fluke, that company sucks with how they treated SparkFun
Fluke replaced all those crappy $15 meters with Fluke products to Sparkfun free of charge. Sounds like a pretty good company to me.
