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
