Thank you for you answer, but i already looked there and there are 3 usable VI for configuration : range deadband and attribute configuration.
Range and deadband have nothing to do with the scaling value.

Here is the list of the configurable attibute:




Input Filter\Noise Rejection, Thermocouple Type, CJC Source, RTD type, Terminal Count, Terminal Count (MSB), Count Source,
Gate Source, Read Reset Mode, Output Source, Output Mode, Period, Period (MSB), Pulse Mode, On Time, On Time (MSB),
Off Time, Off Time (MSB), Resolution, Reset Mode, Excitation Voltage, Half Bridge Completion, Measurement Mode.
No sign of scaling value attribute, snif.
