5.  Press the Output key. The 
voltage can now be 
controlled with the isolated 
external voltage control. 
The input impedance for isolated external voltage 
control is 1MΩ. 
Use a stable voltage supply for the external voltage 
control.  
CV and CC Slew Rate Priority are disabled for V-I mode 
(F-03) when using external voltage control. See the 
normal function settings on page 101. 
Ensure the voltage polarity is correct when connecting 
the external voltage.  
Ensure no more than 10.5V (for the 0~10V setting) or 
5.25V (for the 0~5V setting) are to be input into the 
isolated voltage input. 
Isolated External Voltage Control of Current Output 
 
Voltage control of the current output uses the 
isolated voltage option (PSU-ISO-V). A voltage of 
0~5V or 0~10V is used to control the full scale 
current of the instrument, where: 
For 0~5V: Output current = full scale current × 
(external voltage/5) 
For 0~10V: Output current = full scale current × 
(external voltage/10)
