2X4 Test Leads
Introduction
The optional Fluke TL2X4W test leads simplify making 4-wire ohms measurements by
integrating the HI+HI Sense and LO+LO Sense test leads into one cable. The Meter’s
Input HI and LO jacks consist of two contacts. One contact is connected to HI or LO
input circuits and the other contact is connected to the Sense input circuits. Like the input
jacks, the 2x4 test lead also has two contacts that align with the input jack contacts to
provide a four wire connection.

XW Warning
To avoid electric shock and possible damage to the Meter, use
the 2X4 Wire test leads as specified in the instruction sheet that
comes with the probes. Inspect the test leads before use. Do
not use them if insulation is damaged or metal is exposed.
Check the test leads for continuity. Replace damaged test leads
before using the Meter.
