Digital Control the On/Off state of the instru-
input ment. When 0V is input, the instrument
state is switched to Off; when 5V is in-
put, the instrument state is switched to
On.
Digital Indicate the instrument's loading state:
output Under normal loading state, 5V is out-
put; under non-loading state, 0V is
output.
Digital Indicate the instrument's working
output state: Under the CC mode, 5V is out-
put; otherwise, 0V is output.
Digital Indicate the instrument's fault state: If
output the instrument is normal, 5V is output;
if the instrument is abnormal, 0V is
output.

Analog Monitor the voltage, and output 0 ~
output 10V voltage value to monitor the DC
terminal voltage between 0 and full
scale.
Analog Set current. The input range varies
input under different modes.
Under the source mode:
•
When CV is prioritized, input 0 ~
10V voltage value to set the nega-
tive current limit (I_Lim- value) be-
tween 0 and negative full scale;
•
When CC is prioritized, input –10V
~ 10V voltage value to set the cur-
rent value between negative full
range and positive full scale;
