The input impedance for external voltage control is
10kΩ.
Use a stable voltage supply for the external voltage
control.
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.
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 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
(Ext-R ) 10kΩ~0kΩ(10kΩ = 0).
For 0kΩ~10kΩ: Output voltage = full scale
voltage × (external resistance/10)
For 10kΩ~0kΩ: Output voltage = full scale
voltage × ([10-external resistance]/10)
