Use a screwdriver to adjust the
output sigal frequency:
Total frequency range: Q ~ 0.05Hz - 100kHz
clockwise
UP DOWN
counter clockwise
SW1: Frequency
range selector:
Output voltage signal parameters:
Units: frequency [kHz]; tH, tL [ms]; Ra, Rb [Kohm]; C [uF]
position 0: 100Hz
position 1: 1kHz
position 2: 10kHz
position 3: 100kHz
J1: Output function settings
J2: Output voltage level settings
Use output voltage signal as:
- interrupt (INT)
- general purpuse analog/digital
(OUT) MCU input
