About the 4-Terminal Lead of resistance meters

QAre there any other measurement leads that can perform 4-terminal resistance measurement other than model 4-Terminal Lead L2104? (Resistance Meter RM3545)

A

Yes, there is. 
All optional measurement leads of the RM3545 have a 4-terminal structure, so "4-terminal resistance measurement" is possible.
Although they have different names, such as Clip Type Lead L2101 and Pin Type Lead L2102, they can be used by attaching to the Resistance Meter RM3545 and RM3544.
Models L2104 and 9453 are called "4-terminal lead" because they have four separate tips.
