The Model 2790 uses the forced constant-current method to measure resis-tances less than 1kW . In this technique, the instrument sources a constant current (I) to the resistance and measures the resulting voltage (V) . The amount of current sourced is programmable from 0–50mA . Resistance (R)is calculated (ａnd displayed) using the known current and measured volt-age (R = V/I) . A 20mV dry circuit clamp is available at sourcing levels up to 1mA for preserving the oxide layers on connectors and other components .
