How to measure potentiometer resistance
Web22 mei 2024 · An attenuator at the power amp input can be either a pot, or fixed resistors if you know. the amount of loss needed. If you have a solid state preamp, use either a 10k pot, or a series 10k resistor and a shunt 2k resistor. Adjust the 2k up or down in value, if needed. A tube preamp would need higher values, such as a 100k pot instead of a 10k pot. Web12 okt. 2024 · 1. Choose the item whose resistance you wish to measure. For the most accurate measurement, test the resistance of a component individually. Remove the component from the circuit or test it before you install it. Testing the component while still in the circuit can cause inaccurate readings from other components.

Web23 jul. 2009 · R = 12/.333. R = 36.036 Ohms. In short, you need a trim pot with a range of 15 (that is 36.036 - 21.021)Ohms. And the way you start your low end at the proper resistance is by putting a 21 Ohm (more likely a 22 is what you can get) resistor on … WebTo measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below).
