The ADC-100 has a 12 bit ADC inside of it. The driver outputs the counts from this ADC with values ranging from 0-4095. 0 would be the farthest negative value and 4095 would be the farthest positive. So if you are on the Â±20V scale 0 would be -20V and 4095 would be +20V. To convert the ADC counts to volts you would use the following formula.
(ADC Count -2048) X Selected Voltage Range / 2048 = Voltage Reading.
So, if on the Â±20V scale and a ADC reading of 1233 the formula would look like this:
(1233 - 2048) X 20 / 2048 = -7.958984375V
To ensure accuracy of your experiment I would leave the trailing numbers intact in your program. If however you still wish to have only voltage values and not the trailing numbers simply use Visual Basics round function to round the number up to the next whole number.
