The voltage measurement cable has been broken during the earth continuity testing performed by TOS series (with the four-terminal wiring method). Does it affect the measurement result?

Yes, the measured resistance value will be higher than the actual resistance value, because the resistance of the current output cable is also added to the measurement result.

Even if you use the four-terminal wiring method, the measurement accuracy cannot be maintained.
Perform the pre-inspection before testing.
