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.
Note
The input impedance for external voltage control is
10k
Ω.
Use a stable voltage supply for the external voltage
control.
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.
External Voltage Control of Current Output
Description
External voltage control of the current output is
accomplished using the MIL-26 connector on
the rear panel. A voltage of 0~10V is used to
control the full scale current of the instrument,
where:
Output current = full scale current × (external
voltage/10)
