we want to use the PicoLog1216 to measure the current of the 12V bar of a Personal Computer's power supply unit. Therefore we created a test circuit to measure the voltage on a 10mOhm resistor. A typical range of values we observed in this setting is between 2 to 4 mV of voltage.
If I got it right, the resolution of the PicoLog1216 is 12 bit over the range from 0 to 2.5V, thus the smallest unit which can be resolved is 2.5V/4096 = 0.61mV. However in our setting we want to collect finer grained values to make accurate conclusions on the current drawn by the 12V bar (s.th. around 0.1 mV would be nice)
My question is if the PicoLog1216 can either preamplify the measured voltage or if it can distribute its resolution of 12 bit over a smaller range (e.g. measuring from 0V to 100mV with 12bit resolution.)
Thanks for help
