The R8340A digital ultra-high resistance/micro current meters
use an input amplifier gain switching type I-V converter, highspeed
sampling A/D converter and low-noise high-response
voltage generator. They are fast and precise, with a range from 10 fA to 19.999 mA for current measurement and 10 to 3 - 1016 for resistance measurement.
