#179890 - Put a load on it while measuring the signal Responding to: ???'s previous message |
You find out the source resistance by measuring the voltage with and without a known load while the strain gauge has a fixed force applied.
You then get a voltage divider where you can compute the output resistance of their signal conditioner. It's harder to measure any capacitive/inductive components, since you may not be able to apply any vibration of controllable amplitude/frequency to the strain gauge. |
