The following is measured:
protective earth leakage current 
Direct measuring method  Current in protective conductor, mains power on
Differential current measuring  Difference between current in L and N, mains power on
Alternative measurement  Probe to N+L
Equipment leakage current 
Direct measuring method

Current in protective conductor + current in probe,
mains power on
Differential current measuring

Difference between current in L and N + current in the
probe, mains power on
Alternative measurement  Probe connected to the protective conductor, to N+L
Touch cu rrent 
Direct measuring method  Current in the probe, mains power on
Differential current measuring

Difference between current in L and N, PE interrupted,
mains power on
Alternative measurement  Probe to N+L
Leakage current from applied part 
Direct measuring method  Current in the probe, mains power on
Differential current measuring  Probe to N+L+PE
Alternative measurement 
earth leakage current  Current in protective conductor, mains power on
patient leakage current  Current in the probe, mains power on
