THE BEST Multimeter Tutorial

The voltmeter… the Volt-Ohm Meter… the Multimeter… digital or analog… continuity… amperage, voltage and ohms… COME ON, MAN!  What is it and how hard is it to use in the every day life of a ham radio enthusiast or just someone working in their workshop?  Once again, Afrotechmods has an excellent tutorial on his YouTube channel for us to learn from!

Regardless if it’s your flashlight, your 2 Meter hand-held radio, your QRP rig, your Field Day station(s), your APRS setup, your balloon launch radio transmitter, your trolling motor, your emergency preparations or your personal GoBox… understanding how long those batteries that supply operating power will last becomes quite important.  It will also assist you in deciding what battery to select for a particular project or product.  Afrotechmods has several excellent YouTube videos on his channel that we all can enjoy!
