Voltage Range

Post by aamjad.iqbal » Mon Jan 21, 2013 5:16 pm

hej!
I am using picoScope4227 with labVIEW.

Is there any possible way that LabVIEW changes voltage range automatically depending upon input ??
as when i have small input voltage like 5mV and voltage range is set to 50mV then output is approximately correct but when i change the voltage range to 1V then error increase. Same way when my input voltage is large like 300mV and voltage range is 50mV, again output have some error.
Actually i want to get any error free output which is only possible that if the voltage range changes automatically according to input voltage.
Can you help me in that ???

regards,

mV = (ACD count x mV range) / max value (max value = 32764)

I am using this formula to convert ACD to Voltages
