Preparation | Preparing for Connecting a DUT
 Taking measures against noise
When connecting cables that have the same heat resistance, separating the cables as much as possible
to increase heat radiation enables a greater amount of current to flow. However, wiring the + (positive) and
- (negative) output wires of the load cable side by side or bundling them together is more effective against
unwanted noise. The Kikusui-recommended currents shown in the table
(p.22) are allowable currents that
have been reduced in consideration of the potential bundling of cables. Use these values as a guideline
when connecting cables.
 Limitations of the remote sensing function
All wires have resistance. As the wire becomes longer or the current increases, a drop in voltage across
the wire becomes bigger. That means the voltage applied to the DUT terminal becomes small. This
product has a sensing function that compensates for this voltage drop up to approximately 1 V for a single
line. If the voltage drop exceeds this level, use cables that have a greater cross-sectional area.
Constructing cables
The optional set of output cables, TL13-PFX and TL14-PFX, are available (p.47) . The provided necessary
processing of the cables facilitates the connection, saving wiring time. We recommend using the optional
set of output cables to connect a DUT.
For information about options, contact your Kikusui agent or distributor.
