→Digital Multimeter
==Digital Multimeter==
==Digital Multimeter==
A digital multimeter can measure a host of electrical properties including DC voltage and current, AC voltage and current, resistance, continuity, frequency, period, dB, dBm, True RMS AC+DC, and diode testing.
===Controls===
The buttons you need to be most familiar with when using the digital multimeter are the function keys: DC V, AC V, Ω, Freq, AC+DC, and diode (that's what that symbol is). To access the functions written in blue, press the shift key and then press the respective function key. The blue functions include: DC I, AC I, Continuity, Period, dB, dBm. Let's talk about all of them very briefly.
The DC V function will measure a DC voltage
===Plugging In The Leads===
It is very important that you plug in the leads (cables, banana jacks, whatever you want to call them) into the correct terminals to make your measurement. The correct input terminals can change depending on what type of measurement you are performing. Failure to choose the correct terminals and set up the measurement properly can result in a blown fuse, damage to the digital multimeter, damage to another benchtop instrument, and/or damage to your circuit. So... read what each terminal is meant for before you start plugging things in willy-nilly.
