Features
Properties of a product. Variable features are the measurable properties
of a product subject to change or variability; e.g., -ferrite content is a
variable feature. Attributive features are the properties of a product that
usually cannot be captured by taking measurements. Examples are, de-
viations in color, or whether the product is true to gauge size.
“Free-running” display
With the probe placed on the specimen, measurements are displayed
continuously. Indicated by a p on the display of the FERITSCOPE
