How to use the multimeter: the use of the ohm block
1. Select the appropriate magnification. When measuring resistance with an ohmmeter, an appropriate magnification should be selected so that the pointer indicates near the median value. It is best not to use the left third of the scale, which is poorly scaled.
2. Adjust to zero before use.
Three, can not live measurement.
4. The measured resistance cannot have a parallel branch.
5. When measuring the equivalent resistance of polar components such as transistors and electrolytic capacitors, you must pay attention to the polarity of the two pens.
6. When measuring the equivalent resistance of nonlinear components with ohm blocks of different magnifications of the multimeter, the measured resistance values are different. This is because the median resistance and full-scale current of each gear are different. In mechanical watches, the smaller the magnification, the smaller the measured resistance value.
