Different values for the feedback resistor in the recommended FlexiForce circuitQuestion/Problem: What is the effect of changing the value of the feedback resistor used in the circuit in the manual? Answer/Solution: If you are using our recommended circuit, a feedback resistor at half the recommended 20 kOhm value will increase the range -- to about double its stated range (up to ~0-50 lbs from ~0-25 lbs). If you only interested in measuring forces up to 4.5kg (~10 lbs), you should double the feedback resistor (rather than halving it). A feedback resistor of about 40kOhm would decrease the dynamic range to about 0-12 lbs. If this did not answer your question, please try searching again or contacting us at
