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.
Note
The input impedance for external voltage control is
10k
Ω.
Use a stable voltage supply for the external voltage
control.
CAUTION
Ensure the voltage polarity is correct when
connecting the external voltage.
Ensure no more than 10.5 volts are input into the
external voltage input.
External Resistance Control of Voltage Output
Description
External resistance control of the voltage output
is accomplished using the MIL-26 connector on
the rear panel. A resistance of 0kΩ~10kΩ is
used to control the full scale voltage of the
instrument.
The output voltage (0 to full scale) can be
controlled with the external resistance going up
(Ext-R
) 0kΩ~10kΩ(10kΩ = Vo,max) or down
