20 : 10 : 39 : 28 . Conducting the cow contact test. The selection of cow contact points to be tested shall include a number of locations reasonably likely to demonstrate the presence of stray current or stray voltage, if any. The voltage across the shunt resistor or current through the shunt resistor is measured between cow contact points. The source resistance is calculated during analysis for all cow contact points.
