Indicate the scaling to use when converting data from native format to doubles
Description
NativeScaling, along with NativeOffset, is used to convert data from your hardware's native format to doubles using the formula
For analog input objects, you return data from the engine in native format using the getdata function. Additionally, if you log native data to a .daq file, then you can read back that data using the daqread function. For analog output objects, you queue native data in the engine using the putdata function. You may want to return or queue data in native format to conserve memory and to increase speed.
The NativeScaling value for a given channel may change if you change the UnitsRange, SensorRange, or InputRange property values for that channel.
You can return the native data type of your hardware device with the daqhwinfo function.
