The specifications for connections with CURRENT and VOLTAGE (SENSE) require four wire
connections as standard. Use these terminal posts are detailed in the section below.
For the case to act as a shield the EARTH terminal must be connected to earth ground or
instrument guard at some point in a calibration configuration. When connecting two or more
instruments with guards, the use of a single common earth point avoids earth loops.
Connection Recommendations
For optimum results use two sets of low thermal test leads which are designed to reduce
