Voltage control of the voltage output uses the 
isolated voltage option (PSU-ISO-V). A voltage 
of 0~5V or 0~10V is used to control the full 
scale voltage of the instrument, where: 
For 0~5V: Output voltage = full scale voltage × 
(external voltage/5) 
For 0~10V: Output voltage = full scale voltage × 
(external voltage/10) 
When connecting the external voltage source to 
the isolated voltage option, use shielded or 
twisted paired wiring. 
 
  Pin4(GND_ISO) → EXT-V (-) 
  Pin2(+VPROG_ISO) → EXT-V (+) 
  Pin 1 or 8 (Shield) → Wire shield
