How do I use the multiple stops on the multimeter resistance?
Multimeter resistance gear in the role of several gears are:
1, measuring resistance range, is for you to measure the resistance value is to choose the right range of the measured value of the error is smaller, more accurate.
If you are 1000 ohms resistance, you will use the 2000 gear measured value than the 20K measured more accurate, that is, you measure the resistance value of the resistance of the closer to the gear, the measured value of higher accuracy.
2,0-200Ω用200档;200-2000Ω用2000档;2000-20k用20K档;20K-200K用200K档;
Operation specification
1,Be familiar with the functions of the multimeter before use, according to the object to be measured, the correct choice of gears, ranges and pen jacks.
2, in the size of the measured data is not clear, should be the first range switch, placed in the maximum value, and then by a large range to switch to the small range gear, so that the instrument pointer indicates in the full scale 1/2 above the place can be.
3, the measurement of resistance, after selecting the appropriate multiplier file, the two pens touch so that the pointer in the zero position, such as the pointer deviates from the zero position, you should adjust the "Zero" knob, so that the pointer to zero to ensure that the measurement results are accurate. If you can not zero or digital display meter issued a low-voltage alarm, should be checked in time.
4, in measuring the resistance of a circuit, you must cut off the power supply of the circuit under test, and do not measure with electricity.
5,When using the multimeter for measurement, pay attention to the safety of the person and instrumentation equipment, the test shall not touch the metal part of the meter pen with hands, and do not allow switching the gear switch with electricity to ensure accurate measurement and avoid accidents such as electrocution and burnt instrumentation.
