The function provides both 2-wire and 4-wire measurements of resistance, in decade
ranges from 20 MΩ to 20 GΩ
. The measurement is performed at High Voltage
using a current source with high compliance. The resulting increase in Current
through the unknown resistor is valuable to the reduction of leakage and bias
current uncertainties. The function may also be used alongside the normal Ohms
function to determine Voltage Coefficient in the unknown resistor.
