2. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   Analog multimeter Digital 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.

3. Class of accuracy in electrical measurements - Wikipedia

   en.wikipedia.org/wiki/Class_of_accuracy_in...

   In electrical engineering, characteristics like current or voltage can be measured by an ammeter, a voltmeter, a multimeter, etc.The ammeter is used in series with the load, so the same current flows through the load and the ammeter.

4. Continuity test - Wikipedia

   en.wikipedia.org/wiki/Continuity_test

   In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.

5. Voltmeter - Wikipedia

   en.wikipedia.org/wiki/Voltmeter

   Instruments permanently mounted in a panel are used to monitor generators or other fixed apparatus. Portable instruments, usually equipped to also measure current and resistance in the form of a multimeter are standard test instruments used in electrical and electronics work. Any measurement that can be converted to a voltage can be displayed ...

6. Metric system - Wikipedia

   en.wikipedia.org/wiki/Metric_system

   A kilogram mass and three metric measuring devices: a tape measure in centimetres, a thermometer in degrees Celsius, and a multimeter that measures potential in volts, current in amperes and resistance in ohms. The metric system is a decimal-based system of measurement.

9. ESR meter - Wikipedia

   en.wikipedia.org/wiki/ESR_meter

   An ESR meter does not measure the capacitance of a capacitor; the capacitor must be disconnected from the circuit and measured with a capacitance meter (or a multimeter with this capability). Excessive ESR is far more likely to be an identifiable problem with aluminium electrolytics rather than out-of-tolerance capacitance, which is rare in ...
