Earth loop impedance tests

I am often required to measure earth fault loop impedance of low voltage systems in various buildings. Now the tester has a soft test option that will not trip out residual current devices. As far as I am aware it uses a capacitor timing circuit. Has anyone a better handle on its operation?
