Two-conductor type : Since a conductor resistance is added to the resistance value, it is necessary to reduce the conductor
  conductor in advance. This type is not usually used, except for a high resistance RTD's
Three-conductor type : Use to eliminate the effect of conductor resistance, care should be taken for long-distance fransmisson
  because a variation of resistanceconductors has an effect on accuracy. this type of connection is most
  widely ysed in industrial applications.
Four-conductor type : This type of connection is used for high-accuracy measurement and standards because it is not
  affected by conductor resistance. Generally, a constant is applied and the resistance value is
measured by a potential difference.
