In combination with the alligator clips N1426C, it accepts test items with large connections. Together with the needle tips N1426A, it is suitable for measurements on small DUTs such as PC boards or IC sockets. With the soldering base N1426B and the N1425A you can create simple customer-specific test leads. To connect the test lead N1425A to the B2985A / B2987A, the N1413A high-resistance measuring adapter is also required.
