Thanks for the information Martyn, I did not appreciate what these functions did (I just had a vague idea that they were for external sensors). Anyway, after altering the signal source slightly to try and improve its sensitivity, I changed to the +-1.25V range using the functions you suggested. The ...

I've been asked to write an application for the Raspberry Pi that uses the DrDAQ data logger to record a low level voltage (100 - 200mA at most). I've written the application but found there are only three data points at a peak in the signal. Is it possible to reduce the voltage range using the SDK,...
