and 0 kΩ will set the minimum voltage/current output, which is 0 V/0 
A (The scale factor is linear to the full scale voltage/current output).  
See the setup below: 
Note: Two separate variable resistances 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 resistance is 
used for voltage, current setting will remain 0. If resistance is 
used for current, voltage setting will remain 0.
