2. Capacitance meter - Wikipedia

   en.wikipedia.org/wiki/Capacitance_meter

   A multimeter in a resistance range can detect a short-circuited capacitor (very low resistance) or one with very high leakage (high resistance, but lower than it should be; an ideal capacitor has infinite DC resistance). A crude idea of the capacitance can be derived with an analog multimeter in a high resistance range by observing the needle ...

3. Capacitive sensing - Wikipedia

   en.wikipedia.org/wiki/Capacitive_sensing

   Capacitance is typically measured indirectly, by using it to control the frequency of an oscillator, or to vary the level of coupling (or attenuation) of an AC signal. Basically the technique works by charging the unknown capacitance with a known current, since rearranging the current–voltage relation for a capacitor,

4. ESR meter - Wikipedia

   en.wikipedia.org/wiki/ESR_meter

   Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...

5. Capacitive displacement sensor - Wikipedia

   Sometimes they are used to test assembled parts for uniformity, thickness or other design features. At other times, they are used to simply look for the presence or absence of a certain component, such as glue. [9] Using capacitive sensors to test assembly line parts can help to prevent quality concerns further along in the production process.

6. LCR meter - Wikipedia

   en.wikipedia.org/wiki/LCR_meter

   An LCR meter can also be used to measure the inductance variation with respect to the rotor position in permanent magnet machines. (However, care must be taken, as some LCR meters will be damaged by the generated EMF produced by turning the rotor of a permanent-magnet motor; in particular those intended for electronic component measurements.)

   A male humpback whale made one of the longest and most unusual migrations on record for the species, an anomaly scientists say might be linked to climate change.
