WebSet the selector dial to Ω. Connect the test lead and probes to the component terminals as shown (Figure 4). Observe the readout window to obtain the Ω reading. Compare the results to the manufacturer’s Ω specifications. If the readings match the component, then resistance is not a problem. WebA straightforward way of improving the accuracy of a resistance measurement is to use a "4-wire" measurement. Resistance measurements are done by applying a stimulus current, and measuring the voltage across the resistor. The 4-wire measurement uses separate leads for the stimulus and measurment: WebThe first measurement measures the total resistance of the sensor and the connecting lead wires. The second measurement is the resistance of the compensation loop resistance. By subtracting the compensation loop resistance from the total resistance, an account net resistance is determined. norstray nuart s a s

"WebAug 10, 2016 · R2 we don't know. Using the ADC of the Arduino we measure a value of 681. First we convert that into a voltage: Vout = 681 / 1024.0 * 5.0 = 3.325V. So we know that R2 has 3.325V dropped across it, and since all the voltages must add up to 5V we know that R1 has (5 - 3.325) 1.675V dropped across it. " - How do i read resistance
