la charge de la résistance en dérivation/parallèle Explanation: shunt (resistance) loading : " corrects for shunt loading based on the 10 M input impedance" "Shunt Resistance Loading and GuardingExternal shunt resistances, such as leaky cables and dirty insulators, may also cause loading errors.Any external shunt resistance across the voltage source will attenuate the measured voltage, as shown in Figure 2-3. As in the case of input resistance voltage loading, the shunt resistance (RSHUNT) and the source resistance (RS) form a voltage divider that reduces the measured voltage (VM) as follows:RSHUNTVM = VS––––––––––––––( RSHUNT + RS ) For example, assume RS = 10GW and RSHUNT = 100GW. If VS has a value of 10V, the measured voltage (VM) is:1011VM = 1 0––––––––––––( 1011 + 1010)VM = 9.09VIn this instance, the error due to shunt loading is approximately 9%" https://www.testequity.com/documents/pdf/keithley/KeithleyLo...
