Precautions for module use:
(1) The power supply of the module is a dual power supply, and the voltage cannot exceed ±15V
(2) Since the module is a high-precision device, for your unnecessary interference, it is recommended to use a linear power supply
(3) For the output signal, it is recommended to use a good wire for input and output signals, and use an oscilloscope to observe the effect.Poor contact or poor quality wire may cause signal attenuation or excessive noise.
Frequently Asked Questions:
Q: How to adjust zero when the module is single-ended input?
A: The module defaults to a single-ended input. After
