What is the minimum voltage value that can be measured accurately?
If good low thermal construction techniques are used, repeatability of a few nanovolts [10^-9V] can be obtained. To this must be added the accuracy specifications of the instrument. A very good cost-effective solution for low voltage measurement is the 2182. For picovolt resolution and measurements, the 2002 DMM and 1801 Nanovolt Preamp is the most sensitive room temperature digital nanovoltmeter available.
