What is the method of measuring resistance with a multimeter?
In order to make the measurement more accurate, the pointer should be placed near the center of the scale line. If the deflection angle of the indicator is small, the R * 1K file should be replaced. If the angle of the indicator is large, the R * 1O or R * 1 files should be changed. After each shift, adjust the ohm zero adjustment knob again and then measure.
Two probes are respectively measured contact resistance of the two pin test. Correctly read the value of the resistance indicated by the pointer, and then multiply the magnification (R * 100 files should be multiplied by 100, R * 1K files should be multiplied by 1000....). Is the resistance value of the resistance to be measured.
The ohmmeter can measure the resistance of a conductor. The ohm gear is represented by "Omega", divided into R * 1, R * 10, R * 100 and R * 1K four files. Some meters, and R * 10K files. The use of multimeter, ohmmeter, resistance measurement, in addition to the requirements mentioned above before use, should also follow the following steps. 1. the selection switch at R * 100 stalls, two pens and short circuit adjusting zero adjustment knob at the ohm position, the resistance at the right end of the zero line. If the pointer cannot be set to zero, the battery voltage is not enough, so the battery should be replaced.
