- This one covers the use of the auto ranging multimeter including capacitor tester, micro amps, DC millivolts, DC volts, AC volts, ohm meter, megohm meter
This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.

This is one of the best demonstrations of the use of a autorange multimeter for any C/Heating repairs
I have watched a thousand of these videos online this evening trying to figure out of my capacitor is dead in my HVAC, and this is the best illustrated and most helpful video online. It is just a shame I did not find it earlier. Thanks for taking the time to make this video.
Fluke 16 is a great multi-meter. I have had one for years and it is still going strong.

I believe they were the first to make a meter that I could not break. Most of the commercial meters are protected now but I get your point.
GFM
Fluke has had their problems with some of their new meters. Thanks for commenting.

I hate that fluke stopped making the 16!I have one that i use every day.I bought a 116 but never really liked it.Enjoyed your video.
There are "cheaper" meters out there that are viable for commercial usage. As to the very cheap meters, they are ok for the homeowner that uses them occasionally in some cases. But continued use every day as a tech would do, will damage the meter and be dangerous for the user. Check the meter playlist on my channel. Hope it helps.

Glad I helped.

A veces escribir notas en mis manos. No puedo recordar lo que era.

thank you...
Hey Gray.. this is a noob question. Can we use the Common on the furnace control board when checking for 120v ac throughout the furnace?
The voltage on the Ohm side is the LoZ setting it's used to eliminate ghost voltages if you have induced interference from other circuits it provides a Low 2 K resistance it shouldn't be used on control circuits
Robert Reed Thanks for the info.GFM

can i get a link for part 1-5?
+Angel Bardin Try this: ruclips.net/video/b3waUZ-MgWc/видео.htmlI will set up links.

You skipped continuity which is a function on the diode setting. Poor oversight.
Is the ac symbol called a sine wave or skwiggly line?? Plz use grown up language sir
prettytoney09 Does it matter? No, really, does it matter? I ask because he’s literally demonstrating it his way. It has nothing to do with “grown-up language.”
Have any other “brilliant” theoretical advice to give him?
