5.1.4
Connection for High Current Measurement
Be sure to use 4-wire connection to measure high current.
Twist together the cables between
HI OUTPUT
and
LO OUTPUT
and between
HI SENSE
and
LO
SENSE
from the output terminals to the DUT terminals as in Figure 5-6 to avoid overshoot or delay in
response because of cable inductance.
Use twisted pair shielded cables for
OUTPUT
and
SENSE
as in Figure 5-6 to prevent induction noise.
Especially, be sure to use shielded cables when measuring current of 1
A or less.
The cables for
OUTPUT
must satisfy the thickness requirement below, and the voltage difference
between
OUTPUT
and
SENSE
must be 1.0 V or less for both HI and LO.
Be sure to set the voltage between the
HI SENSE
and
LO SENSE
terminals within the maximum output
range.
