Hello every body,
I want to calibrate my bridge for sensor data acquisition. For that i have three resistors of 350 ohms in the bridge circuit and fourth one is the variable resistor. I always have to set it manually. I want to use programmable resistor (digital potentiometer) instead of manual potentiometer but unable to find it, that can go upto 350 ohms.
Can any body of you suggest any other method through which i can do the nulling or calibration? or any programmable resistor that can go below 350 ohm or atleast upto 350 ohms ?
Looking forward for your suggestions.
