How to Test a Diode using Multimeter
A multimeter can be used as a fast and simple way to check a diode out of the circuit. A good diode will show an extremely high resistance (ideally an open)...
How to Measure Duty Cycle using Multimeter
Duty cycle basics Duty cycle is the ratio of time a load or circuit is ON to the time a load or circuit is OFF. A load that is turned...
How to do Continuity Testing using Multimeter
Continuity Testing using Multimeter Turn the dial to Continuity Test mode ( ). It will likely share a spot on the dial with one or more functions, usually resistance (Ω)....
How to Measure AC Voltage using Multimeter
1. Turn the dial to ṽ. Some digital multimeters (DMMs) also include m ṽ . If voltage in the circuit is unknown, set the range to the highest voltage setting...
How to measure frequency using Multimeter
If your digital multimeter offers a frequency setting (Hz is the symbol) on the dial: Turn the dial to Hz. It usually shares a spot on the dial with at...
How to Measure capacitance using Multimeter
A multimeter determines capacitance by charging a capacitor with a known current, measuring the resulting voltage, then calculating the capacitance. Warning: A good capacitor stores an electrical charge and may...
