The Advantest R8340 Ultra High Resistance Meter is a precision instrument engineered for measuring extremely high resistance values and micro currents across insulation testing and material characterization applications. The meter combines an input amplifier gain switching type I-V converter, high-speed sampling A/D converter, and low-noise, high-response voltage generator to deliver both speed and measurement accuracy across an exceptionally wide dynamic range.
