ENR (*.enr) Files
— ENR files are saved to, and recalled from, the NoiseFigure\ENR folder. If the
folder does not already exist on a USB or SD card, it is created
automatically before storing the file.
— ENR files are stored as *.enr files. Existing ENR files that are loaded into the
FieldFox can be overwritten. Your edited file will NOT be overwritten when
firmware is updated.
—To DELETE a *.enr file, use the Manage Files feature. Learn more in
“Manage Files” on page 680.

(when a given auto-populate value
is turned on, its value fills in the
associated values in the table).
