2. Trimmer (electronics) - Wikipedia

   en.wikipedia.org/wiki/Trimmer_(electronics)

   Trimmers come in a variety of sizes and levels of precision. For example, multi-turn trim potentiometers exist, in which it takes several turns of the adjustment screw to reach the end value. This allows for very high degrees of accuracy. Often they make use of a worm-gear (rotary track) or a leadscrew (linear track). [1]

3. Potentiometer - Wikipedia

   en.wikipedia.org/wiki/Potentiometer

   Linear taper potentiometers [4] are used when the division ratio of the potentiometer must be proportional to the angle of shaft rotation (or slider position), for example, controls used for adjusting the centering of the display on an analog cathode-ray oscilloscope. Precision potentiometers have an accurate relationship between resistance and ...

4. Laser trimming - Wikipedia

   en.wikipedia.org/wiki/Laser_trimming

   Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit. Laser-trimmed precision thin-film resistor network from Fluke, used in the Keithley DMM7510 multimeter. Ceramic backed with glass hermetic seal cover. Laser trim marks are visible in the grey resistive material.

5. Digital potentiometer - Wikipedia

   en.wikipedia.org/wiki/Digital_potentiometer

   While quite similar to normal potentiometers, digital potentiometers are constrained by current limit in the range of tens of milliamperes. Also, most digital potentiometers limit the voltage range on the two input terminals (of the resistor) to the digital supply range (e.g. 0–5 VDC), so additional circuitry may be required to replace a conventional potentiometer, (although digital ...

   Potentiometer – three-terminal variable resistor (variable voltage divider) [8] Trim pot – small potentiometer, usually for internal adjustments; Thermistor – thermally sensitive resistor whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body ...

8. Potentiometer (measuring instrument) - Wikipedia

   en.wikipedia.org/wiki/Potentiometer_(measuring...

   A potentiometer being calibrated and then measuring an unknown voltage. R 1 is the resistance of the entire resistance wire. The arrow head represents the moving wiper.. In this circuit, the ends of a uniform resistance wire R 1 are connected to a regulated DC supply V S for use as a voltage divider.
