CUR
): High current drive
HS(H
POT
): High potential sense
LS(L
POT
): Low potential sense
LD(L
CUR
): Low current drive
Note: Make sure shielding terminals of Hcur and Lcur are reliably short with low impedance
when the test fixtures or cables used don’t come standard with the instrument.
7) Frame terminal
