RLC测量仪作为一款测量仪器，测量精度是一项重要指标。在实际电路中，由

As a measuring instrument, RLC measuring instrument is an important indicator of measurement accuracy. In the actual circuit, due to the influence of environmental factors, there will be some accidental errors more or less, and the high accuracy of the data measured by the simulated circuit cannot be achieved, which affects the final result. In addition to certain accidental errors, there are system errors caused by factors such as internal fixed offsets, some spurious parameters at the input end, and ramp components in the test signal source. In order to improve the accuracy of the RLC measuring instrument, some methods can be used to reduce the error, which can be divided into fixed offset processing, open circuit, short circuit calibration, and random error processing. <br>Before commissioning, first use a multimeter to check whether the line is open or short-circuited. After checking the connectivity of the circuit, plug in the chip and burn the program. If the circuit does not work properly, you must find the reason from various aspects, such as whether the positive and negative poles of the chip, capacitor, light-emitting diode and other devices are inserted in pairs Welding, open circuit and short circuit phenomenon. When debugging for the first time, the light emitting tube has abnormal light emission, and it is impossible to determine whether the power supply is normally supplied to the chip. After checking with a multimeter, it was found that the light-emitting tube was bad, and the good light-emitting tube was replaced immediately. After successfully debugging the program on the experiment board, burn the program to your own board.

As a measuring instrument, RLC measuring accuracy is an important index. In the actual circuit, due to environmental factors, there will be more or less some accidental errors, not to achieve the simulation circuit measured high accuracy of data, affecting the final result. In addition to some accidental errors, the RLC gauge also has system errors caused by internal fixed offsets, some stray parameters at the input end, and the sloping wave components in the test signal source. In order to improve the accuracy of the RLC measuring instrument, some methods can be used to reduce the error, mainly can be divided into fixed offset processing, open circuit, short circuit calibration, random error processing.<br>Before debugging, use a multiple-purpose meter to detect whether the line is open or shorted. After checking the connectivity of the circuit, plug in the chip, burn the program, if the circuit does not work properly, to find the cause from all aspects, such as chips, capacitors, light-emitting diodes and other devices positive and negative pole is plugged in, whether there is virtual welding, open circuit and short circuit phenomenon. The first debugging, the light-emitting tube light-emitting abnormal, can not determine whether the power supply is normal to the chip. After a universal check, it was found that the light-emitting tube is bad, immediately replaced with a good light-emitting tube. After successfully debugging the program on the lab board, burn the program to your own board.

As a kind of measuring instrument, RLC measuring instrument is an important index of measuring accuracy. In the actual circuit, due to the influence of environmental factors, there will be some accidental errors more or less, which can not reach the high accuracy of the data measured by the simulation circuit and affect the final results. In addition to some accidental errors, there are some systematic errors caused by internal fixed offset, some stray parameters at the input end and the oblique wave component in the test signal source. In order to improve the accuracy of RLC measuring instrument, some methods can be used to reduce the error, which can be divided into fixed offset processing, open circuit and short circuit calibration, random error processing.<br>Before debugging, use multimeter to check whether there is open circuit or short circuit in the circuit. After checking the connectivity of the circuit, insert the chip and burn the program. If the circuit does not work normally, find out the reasons from all aspects, such as whether the positive and negative poles of chips, capacitors, light-emitting diodes and other devices are inserted correctly, whether there is faulty welding, open circuit and short circuit. When debugging for the first time, the LED is abnormal, and it is not sure whether the power supply is normal to the chip. After the inspection of the multimeter, it was found that the light-emitting tube was broken. Replace it with a good light-emitting tube immediately. After debugging the program successfully on the experimental board, burn the program to your own board.<br>
