Product Specifications:
Power Interface: Type-C
Input Voltage: DC 5V
Input Current: 1–3A
Frequency: 0.1–299,999 kHz

Frequency Adjustment Method:
Upon powering on, the default frequency is 7.83kHz. Simply enter the desired frequency directly.
For example: to set 888, press the number keys 888 and then press the ‘√’ or ‘OK’ button to confirm. The frequency adjustment method is simple and intuitive.
Usage: We manufacture only the product itself; specific functional applications are developed by the customer. The frequency oscilloscope can be used for testing. The device features a 3.5mm external audio headphone jack; when connected to headphones or speakers, different frequencies will produce distinct audible beeps. The higher the frequency, the sharper the sound. Frequencies above 2000kHz are inaudible to the human ear, whilst those below 2000kHz are clearly discernible. Please be advised. For normal use, the device can be placed by the bedside, in a study or in the living room. The effective range is 10 square metres. For scientific research or experiments, the headphone jack can power LED bulbs of up to 1W.
The accessory list includes a magnetic bead. When placed directly above the antenna, the bead will vibrate in response to the frequency (please note: at very high frequencies, the bead will cease to vibrate; we recommend a frequency range of 0.01–99 kHz).
