2. Set the F-90 power on

configuration setting to 1 (CV

control – Ext voltage).

 Be sure to cycle the power after the power

on configuration has been set.

3. Press the Function key and confirm

the new configuration settings (F-

90=1).

4. Press the Output key. The voltage

can now be controlled with the

External voltage.

Output

Note

The input impedance for external voltage control is

10kΩ.

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 102.

CAUTION

Ensure no more than 10.5 volts are input into the

external voltage input.

Ensure the voltage polarity is correct when

connecting the external voltage.
