5. Press the Output key. The
current can now be
controlled with the isolated
external voltage control.
Output
Note
The input impedance of isolated external voltage
control is 1MΩ.
Use a stable voltage supply for the external voltage
control.
Note
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 99.
CAUTION
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 input into the
external voltage input.
Isolated External Current Control of Voltage Output
Background Current control of the voltage output uses the
isolated current option (PSU-ISO-I). A current
of 4~20mA is used to control the full scale
voltage of the instrument, where:
Output voltage = full scale voltage × ((external
current-4mA)/16mA)
