Regarding measurement of electric contact
Data1
Compare the contact resistance by spring force.
As the spring force is strengthened, contact resistance comes to show low readings, and the dispersion of the value within the same spring force comes to be narrower.
A base material on tips in the data below is Carbon tool steel.
※DUT：Shape: Round/Flat (diameter:Φ16mm height:3mm) Material: Copper (Aurum plating)
※Probe：Type: CP50 Tip Material: Carbon tool steel (Aurum plating)
※Ohm Meter：HIOKI 3560 AC mΩ HITESTER (7.4mA)
