===== Measurement dip switch settings =====
  * Set the voltage or current you want to measure with the DIP switch.
  * Only one of the V and A switches on each channel must be turned ON.
  * V=On / A=Off => Voltage measurement
  * V=Off / A=On => Current measurement

===== Setting the module's address =====
  * Up to 4 CFADC-A4Ls can be used in one system with different address settings.
  * The address setting method is different from other I/O modules. Caution is required.
  * This method turns on only one of the four dip switches.
