SUMMARY
The discussion focuses on measuring the resistivity of iron (Fe) powder samples using a 4-point probe method. The user has previously utilized an I-V measurement system but seeks guidance on preparing the powder sample for the 4-point probe technique. Participants suggest that the preparation process may be similar to that of a 2-point probe measurement, emphasizing the importance of using separate wires for excitation current and voltage measurement paths to ensure accurate readings.
