	Why is adjusting the resistance important? The Voltage Input can measure a voltage between 0V ~~and~~ 5V. When using variable resistance devices a voltage divider is commonly used to measure the changing resistance. The two resistors in the divider form a voltage, based on the ratio between them. This voltage is then measured by the Voltage Input. To optimize the voltage divider to meet your needs, you have to adjust the fixed resistance to match the characteristics of your chosen sensor. To adjust the resistance on the 1121, simply turn the screw on the potentiometer clockwise to decrease the resistance and counterclockwise to increase it. You'll see a change in resistance of about 900Ω to 1000Ω per revolution. First, adjust the resistance for no stimuli on your sensor and then apply the maximum possible stimuli and make sure that sensor's voltage stays within a range that gives you acceptable resolution. At the extremes (less than 0.~~25V~~ or greater than 4.~~75V~~), a very large change in stimuli (and therefore change in the resistance) produces only a small change in voltage. Keep adjusting until you get a range you are happy with.		Why is adjusting the resistance important? The Voltage Input can measure a voltage between 0 and 1.0 voltage ratio (i.e. 0V to 5V if you have a 5V supply).

This voltage is then measured by the Voltage Input. To optimize the voltage divider to meet your needs, you have to adjust the fixed resistance to match the characteristics of your chosen sensor.

First, adjust the resistance for no stimuli on your sensor and then apply the maximum possible stimuli and make sure that sensor's voltage stays within a range that gives you acceptable resolution. At the extremes (voltage ratio less than 0.005 or greater than 0.95), a very large change in stimuli (and therefore change in the resistance) produces only a small change in voltage. Keep adjusting until you get a range you are happy with.
