为了调节记录的开头部分和尾端的振幅电平，通常采用专门的增益控制。
Special gain controls are used to regulate the amplitude levels at the beginning and end of the record.
说明：红外接收处理，根据外部波形记录波形的高低电平时间，从而得到波形数据。
Infrared receiver processing, according to the external waveform waveform record high and low times, resulting waveform data.
通过电平模式中，你可以选择(1到15)的水平发挥，目的是提高水平的个人记录。
By level mode you can select the level to play with (1 to 15) with the aim of improving the level of individual records.
并同时以“时序法”及电平记录仪所测得的信号分析相比较，结果基本相符。
Comparing this result with other one which was obtained from"time serial analysis"and signals detected by electrical record metre we found that both results are very consistent.
