2.2.3 Connection to Unknowns
The KELVIN KLIP® test lead set (Tegam Part No. 43072) is plugged into the 252’s front panel
UNKNOWN connector. The test leads connector cover is spring-locking and should be squeezed together
before inserting or removing.
The test leads provide a shielded, four-terminal connection to the unknown (see Figure 2-5a). The clip
with the red hinge-spool provides the HI DRIVE and HI SENSE connections to the unknown and the clip
with the black hinge-spool make the LO DRIVE and LO SENSE connections.
