Disconnection,160hz~10Mhz High-frequency square-wave output.
PCB size : 17*12mm
High-frequency step is to divide an integer multiple of 10Mhz,You can adjust the frequencies are:10Mhz,10Mhz/2(5Mhz),10Mhz/3(3.3Mhz)...10Mhz/65500(152hz).
Low-frequency step is to divide an integer multiple of 1Khz,You can adjust the frequencies are:1Khz,1Khz/2(500hz),1Khz/3(333hz)...1Khz/65500(0.015Hz).
Low-frequency step is to divide an integer multiple of 1Khz,You can adjust the frequencies are:1Khz,1Khz/2(500hz),1Khz/3(333hz)...1Khz/65500(0.015Hz).
USE:
Short press (less than 2S) be slow to adjust,Short press once, Frequency slow adjustment(Frequency decreases).
Long press (more than 2S) for fast adjustment,When the frequency is adjusted to a minimum.
Short press once again, become the highest frequency
