LCD ON/OFF and deleting feature data
The LCD screen can be turned off without cycling power
when the QC-300 will not be used for an extended period,
but it is desirable to retain the original machine zero en-
coder references. Press the red LCD ON/OFF button to
toggle the LCD on and off.
When the LCD ON/OFF button is pressed, the operator is
given an opportunity to erase all feature measurement data
and resume operation without turning the LCD off. If the
operator presses the Enter key to delete feature data, the
system will ask for confirmation. If confirmation is given,
the feature data and datums will be permanently deleted.
CAUTION
Delete feature data only when you have saved the data in a report, transmitted it to
a computer file or are sure that you no longer need them. Once the data are deleted,
they cannot be restored.
You will be asked to press Enter... and asked to confirm the delete... then the feature data will be deleted
