If the wire shield needs to be grounded at the
voltage source (EXT-V), then the shield cannot
also be grounded at the negative (-) terminal

1. Connect the external voltage according to the
connection diagrams above.
2. Set the F-91 power on
configuration setting to 1 (CC
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-
91=1).
4. Press the Output key. The current
can now be controlled with the
External voltage.
