The 9V battery strainmeter signal adjusting circuit
The 9V battery strainmeter signal adjusting circuit is shown as above.Notes: this is a 9V battery strainmeter signal adjusting circuit, the sampling circuit offers the low average working current of 650μA. As ΔV/ΔT jumps in a high order, the RC net composed of 4.7KΩ and 0.01μF is used to protect the reaction bridge, which avoids the long-term drifting.
