Description:
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.

With Acrylic Shell Version :

1 Working voltage: DC 5V (DC 4-15V)
2 Working current: 9-14MA
3 Power interface: Type-c(Support TYPE-C TO TYPE-C power supply)
4 Default frequency: 7.83Hz
5 Adjustment range: 0.01Hz~100000Hz Pure Sine Wave
6 Signal voltage amplitude: 3V
7 With 3.5MM audio output
8 With acrylic shell
9 Size: 155*105*26MM(With shell)
10 Weight : 197g(With shell)

For more information please Google ''Schumann Resonance''.

(Uses TYPE-C power supply and supports all TYPE-C power supplies.

Note : Since TYPE-C cables are now widely used, no additional TYPE-C power supply cables are provided.)

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
