Steps

1. Connect the external resistance according to the

connection diagrams above.

2. Set the F-91 (CC Control)

configuration settings to 2 for
external resistor rising or to 3 for
external resistor falling.

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 = 2 or 3).

4. Press the Output key. The

current can now be
controlled with the External
resistance.

Output

Note

Ensure the resistor(s) and cables used exceed the
isolation voltage of the power supply. For example:
insulation tubes with a withstand voltage higher
than the power supply can be used.

When choosing an external resistor ensure the
resistor can withstand a high degree of heat.

Note

CV and CC Slew Rate Priority are disabled for V-I
mode (F-03) when using external resistance
control. See the normal function settings on page
99.
