ANALOG CONTROL

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)
