Signal name Description
1 EXT R/V CONT Can be used in CC, CR, CV, and CP modes
0 V to 10 V correspond to 0 % to 100 % of the rated current (CC mode), rated voltage
(CV mode), or rated power (CP mode).
0 V to 10 V correspond to maximum resistance to minimum resistance (CR mode)
0  to 10 k
 correspond to 0 % to 100 % or 100 % to 0 % of the rated current (CC
mode), rated voltage (CV mode), or rated power (CP mode).
0
 to 10 k correspond to maximum resistance to minimum resistance or minimum
resistance to maximum resistance (CR mode)
2 IMON Current monitor output
10 V f.s (H/L range) and 1 V f.s (M range)
3 A COM Connected to the negative load input terminal on the rear panel.
4 SUM I MON Used during master/slave operation. Connected to SUM I MON of the J2 connector.
5 PRL IN+ Used during master/slave operation. Connected to PRL OUT+ of the J2 connector.
6 PRL IN- Used during master/slave operation. Connected to PRL OUT- of the J2 connector.
