Converting 32-bit TIFF to 16-bit erroneous values

I have several thousand TIFF files that I need to convert from 32-bit to 16-bit, but the Copy Raster geoprocessing tool appears to be providing erroneous results.

 

As an example, I have a TIF in 32-bit format with values ranging 0.0241 to 0.0674. When I use Copy Rater and set the "NoData Value" to blank, "Pixel Type" to 16-bit unsigned, set the "Scale Pixel Value" to true, I get a TIFF with values ranging 0 to 32768, but the image appears blank no matter what histogram stretch I use. I have tried Calculating Statistics within ArcCatalog with no results. When I set "Scale Pixel Value" to false, I get values ranging 0 to 1 with an image that appears blank.

 

I am using ArcGIS 10.3.1.

 

Is there something I am missing?
