3.5 ABS/INC Coordinate System Conversion
The DRO gets two sets of standard coordinate system,namely
ABS(Absolute) and INC (Relative) Coordinate.User could set the zero
point of work-piece in ABS coordinate,then switch to INC coordinate for
machining.Zeroing at any position in INC coordinate would not affect
the length value from zero point to current point in ABS coordinate.The
process in ABS would change according to the machining status.User
could switch the coordinate back to ABS for checking.
Example 1: Press to change the current ABS coordinate
to be INC coordinate.

When the DRO is under ABS mode,press 10 times.The left window
will display CLR SDM.At this time,the 200 groups of auxiliary coordinate
has been full cleared.

3.7 Power-off Memory
In case of sudden power off during the machining process,the DRO gets
the data memorize function.Once the power on,the date before power
off will recover automatically.

3.8 Sleep Function
When meet the occasion that the operator would leave for rest,the
DRO could be set as sleep state.To enter the sleep state,the DRO
should not be in ABS model.
Example:Press to enter the sleep state,make sure the DRO is not in
ABS model.
To activate the DRO,press to get back previous machining interface.
3.9 REF Function
In daily machining,we may encounter power failure.If losing the zero
point of the work-piece,we have to retrieve the zero point again.For
the convenience to retrieve the zero point,the DRO could memorize
the mechanical zero reference point of linear scale.This enable the
users to retrieve the zero point of work-piece quickly.

Take note this distance.Turn on the DRO to find the
mechanical reference point of linear scale,then we
could calculate out the preset zero reference point of
work-piece.
(1) Set the mechanical zero reference point of linear scale
Note:To use the REF function,we need to set the mechanical zero
reference point of linear scale in DRO.In this way,the DRO could memorize
the zero point of work-piece.For the following zeroing,centre and value
input for re-locate the zero point of work-piece under ABS model,the DRO
will memorize the distance between new zero point of work-piece and
mechanical zero reference point of linear scale.The operations are shown
as below:
