The output frequency range options by selecting jumper:
| Frequency | Output |
| 1Hz ~ 50Hz | 0.001uF |
| 50Hz ~ 1kHz | 0.1uF |
| 1KHz ~ 10kHz | 1uF |
| 10kHz ~ 200kHz | 100uF |
|
T = 0.7(RA+2RB)C |
|
The output duty cycle can fine-tune;duty cycle and frequency is not separately adjustable; adjusting the duty cycle will change the frequency
