set DAC range in MAX

Hello,
I have a current sensors which in the end is connected to a PCI-6221.
the range of the sensor is -50 to 50A, providing a voltage in range -10 to 10V.
 
the values I expect ro read are in range 0 to 30A.
 
I have created a nidaqmx global virtual channel using automation explorer (MAX), and the channel is linked to a nidaqmx scale.
 
in my software (LabVIEW) i do not create a task, but directly connect the virtual channel to "daqmx start task.vi"
 
my question is: does nidaqmx configure the hardware (setting DAC limits), so that the whole resolution of the card (16bits) is used just in the configured range 0-30A(0-3V)? or do I have to do it myself with a channel property node?
 
thank you in advance
