2. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [ 1] is a measuring instrument that can measure multiple electrical properties. [ 2][ 3] A typical multimeter can measure voltage, resistance, and current, [ 4] in which case can be used as a voltmeter, ohmmeter, and ammeter. Some feature the measurement of additional ...

3. Voltmeter - Wikipedia

   en.wikipedia.org/wiki/Voltmeter

   A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a ...

4. Ohmmeter - Wikipedia

   en.wikipedia.org/wiki/Ohmmeter

   An analog ohmmeter. An ohmmeter is an electrical instrument that measures electrical resistance (the opposition offered by a circuit or component to the flow of electric current ). Multimeters also function as ohmmeters when in resistance-measuring mode. An ohmmeter applies current to the circuit or component whose resistance is to be measured.

5. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   Clamp meter. In electrical and electronic engineering, a current clamp, also known as current probe, is an electrical device with jaws which open to allow clamping around an electrical conductor. This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the ...

6. Capacitance meter - Wikipedia

   en.wikipedia.org/wiki/Capacitance_meter

   Capacitance meter designed by Harry Garland and Roger Melen. A capacitance meter is a piece of electronic test equipment used to measure capacitance, [ 1] mainly of discrete capacitors. Depending on the sophistication of the meter, it may display the capacitance only, or it may also measure a number of other parameters such as leakage ...
