Cal Lock
When enabled (default), the Calibration Lock icon
appear on the display. This prevents an adjustment from
being performed inadvertently if the
pressed.
Cal Memory
The current Cal Setting (ex. Cal 3) is displayed in the upper right
corner of the display. A stored Cal Setting can be selected when
returning to a particular part. Cal 1 can be adjusted but never
deleted, and is always made active with factory settings after a
Reset (pg. 6). A new Cal Setting cannot be created if a batch is
open with readings present.
Edit
Create meaningful Cal Memory names directly on the Gage
using the onscreen QWERTY touch keyboard — helpful when
storing multiple Cal Memory adjustments.
N Lock
Use when operating regularly on non-ferrous substrates.
The icon appears and the probe will only use the eddy current
principle to shorten measurement time and extend battery life.
N
Also useful when measuring coatings over plated or partially
magnetic grades of stainless steel.
