√ Ohmmeter : Pengertian, Fungsi dan Cara Menggunakan

WebStarting with a simple movement and battery circuit, let’s see how it would function as an ohmmeter: When there is infinite resistance (no continuity between test leads), there is zero current through the meter movement, and the needle points toward the far left of the scale. WebFigure 6 illustrates how slip rings work (top), how a cable tester connects to slip rings to make measurements (middle), and the expected resistance samples that constitute PASS and FAIL results. For this application, we modified the tester’s firmware to make repetitive 4-wire Kelvin resistance measurements at the rate of 500 per second. WebThe multimeter starts at the highest (*) range, and if the reading is less than the 199.9 threshold it switches to 1 decade lower, and repeats this until the reading is between 200 and 1999. That goes very fast because it doesn't have to display anything during this procedure, so it appears that it gets the right range first time. proceeding conference
