Description:

Schumann Wave itself does not act directly on sound or video products to improve sound quality, but on the space environment, which can relax people's body and mind, improve the body's perception of sound andimages, improve thehealth of the human body and work efficiency, and relieve psychological pressure. This product not only can output 7.83Hz SchumannWave, but also can adjust the frequency in the range of 0.01Hz-100KHz, the digital circuit crystal oscillator frequency reference, more stable and strong anti-interference.

This is a new version of eletechsup's Schumann Wave adjustable signal generator, which uses a low-temperature drift crystal oscillator and a high-precision DAC dedicated chip. It can accurately output frequency and pure sine wave.

Q&A:

Q1:How to change the output frequency?
A1:Press the ''0-9'' and '.' buttons to enter the value, and press the OK button to confirm. If the input is wrong, press the SET button to re-enter.
For example, press [9][.][7][1], then press [OK], you can set to 9.71Hz, the default power-on output is 9.71Hz, and the setting range is 0.01~100KHz(
Note: Not all frequency points can be set)

Q2:Need to save parameters even after power off?
A2:Please press and hold the ''SET'' button until the LCD displays ''Data Save ON''

Q3: How to verify the output waveform?
A3: Please use an oscilloscope to measure the ''GND/SIN'' port. You can see a pure sine wave.

Q4: How to turn off the LCD backlight?
A4:Short press the ''BACKLIGHT'' button to turn off the LCD backlight; short press the ''BACKLIGHT'' button again to turn on the LCD backlight

Q5:How to turn off the output signal indication (PWR LED)?
A5:Long press the ''BACKLIGHT'' button to turn off the output signal indication; long press the ''BACKLIGHT'' button again to turn on the output signal indication.

Q6:LCD does not display correctly after power on?
A6:Please press the RES button briefly and power on again
