Press the Output key. The voltage
can now be controlled with the
External resistance.
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
108.
External Resistance Control of Current Output
Background
External resistance control of the current output is
accomplished using the MIL-26 connector on the
rear panel. A resistance of 0k
Ω
~10k
Ω
is used to
control the full scale current of the instrument.
The output current (0 to full scale) can be
controlled with the external resistance going up
(Ext-R ) 0k
Ω
