* Question
| What are the two major categories of frequency measurement lines? |
* Answer
| One type is to directly read out the frequency value, that is, the induced potential of the sensor output is amplified and shaped and sent to the counter display or directly by the digital frequency meter; the other is to use the comparison method to read the frequency value, that is, the induced potential of the sensor output.The frequency is compared to the frequency value emitted by a standard oscillator. |
