5.1.4 Connection for High Current Measurement
Be sure to use a 4-wire connection to measure the 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 over-shoot and
response-delay 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 a shielded cable for measuring the current 1 μA or below.
For the OUTPUT cable, use ones that are thicker than listed wire thickness below, and the voltage differ-
ence between OUTPUT and SENSE must be 1.0 V or below for both Hi and Lo.
Be sure to set the voltage between the HI SENSE and LO SENSE terminals within the maximum output
range.
