The Best Multimeter Tutorial in The World

The Best Multimeter Tutorial in The World!

This video compares a 10 dollar to a 170 dollar multimeter and shows the average person how to use the voltage, current, resistance, continuity, diode and battery options. I also cover safety concerns and run all tests simultaneous with both multimeters.

Difference between 3 and 4 prongs on a multimeter

Tests include:
Voltage of Battery
Voltage of Outlet
–> discover something interesting in one of my outlets
–> discover a SERIOUS hazard with the 10 dollar meter
Current of a toaster
Resistor test
Metal Tape test ?
Probing a circuit board
Discovering schematic of a Emergency 4-prong switch
Conductivity of water & salt
Light bulb test (Same as a fuse test)

Funny jokes, disgusting drinks, etc.

Here is a list of other tasks that Multimeters are used for [depending on available functionality]:
–  Get voltage readings of D.C. and A.C. Readings
–  Measure current in a circuit
–  Measure resistances of resistors, circuits, wires, etc.
–  Use continuity check for fuses, wires, electronics
–  Get capacitance readings
–  Measure min/max of voltages, currents, etc.
–  Diode measurements (continuity check)


warningWarning. Improper use or failure to follow the manufactures specifications can result in a broken Multimeter, incorrect readings, damage to the device, and possible injury to yourself and others.


–  Exceeding voltage above the maximum value of the Multimeter as well as probes.
–  Attempting to measure higher current then the rated specifications. If it says 1A max, do not try to measure 1.01 Amp or 10 Amp.
–  Selecting continuity on the multimeter and randomly probing electronics or household devices.
–  Not switching test leads (probes) when switching between current and other tests such as voltage, and continuity.
–  To avoid false readings, replace multimeter batteries as soon as the battery indicator appears.
–  Keep fingers behind the test leads.

    Wow. This was very useful. I never though voltmeters were so handy!! Also salt water drinking was gross.
