will output 0 V. Applying 10 V input for V will output 35 V or 70 V
depending on the range. Likewise, 10 V for I will set current to 3A or
1.5 A depending on the range. See the setup below:
Note: Two separate DC voltage sources must be used for the setup.
One for controlling voltage and one for current. Using one for
either voltage or current will not operate correctly. If source is
used for voltage, current setting will remain 0. If source is used
for current, voltage setting will remain 0.
Resistance Control
You can externally control the voltage/current output with variable
resistances 0 – 5 kΩ. 5kΩ sets the maximum voltage/current output,
