A battery-operated volt-ohm-meter (VOM), or multitester, is a simple, relatively inexpensive testing device that's well worth acquiring if you plan to do electrical repairs. A VOM can tell you whether ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

The Fnirsi LC1020E LCR meter is an affordable yet powerful tool for measuring resistance, capacitance, and inductance with ...

This LC meter circuit can measure coils and capacitors. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter ...
