The input impedance for external voltage control is 
1MΩ. 
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 99. 
Ensure the voltage polarity is correct when 
connecting the external voltage.  
Ensure no more than 10.5V(F-97 = 1) or 5.25 (F-97 
= 0) volts are input into the external voltage input. 
External resistance control of the voltage output 
is accomplished using the analog control 
connector on the rear panel.  
There are two external resistance control 
ranges, 0~5kΩ and 0~10kΩ, depending on the 
F-97 configuration. See page 108 for details. 
The output voltage (0 to full scale) can be 
controlled with the external resistance rising 
0kΩ~5kΩ/0kΩ~10kΩ or falling 
5kΩ~0kΩ/10kΩ~0kΩ.   
Rising: 
For 0kΩ~10kΩ: Output voltage = full scale 
voltage × (external resistance/10) 
For 0kΩ~5kΩ: Output voltage = full scale 
voltage × (external resistance/5)
