 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=2 or 3).
Function
4. Press the Output key. The
voltage 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.
External Resistance Control of Current Output
Background External resistance control of the current output
is accomplished using the analog 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 current (0 to full scale) can be
controlled with the external resistance rising
0kΩ~5kΩ/0kΩ~10kΩ or falling
