I am trying to make a voltage gauge with the LM3914 that will measure over the range of 12-24V. It will be used to indicate the voltage in two 12V batteries connected in parallel. I only want to use one chip to just measure the range in 1.2V steps in the bar mode. I am a little confused though about how I should set up the reference voltage across the divisor to do this?
