Lead-wire resistance in two-wire measurements causes
potentially large temperature measurement errors.
Other types of resistance measurements include three-wire
and four-wire resistance measurements. Four-wire
measurements are preferred in temperature applications
because they eliminate lead wire resistance from the
measurement.
