5.5 Centre Find

Centre Find halves the dimension displayed for any or all axes selected.  You can use Centre Find in either
absolute or incremental mode.  The keystrokes are the same in either case.

In the following example, Centre Find is being used on the X axis to find the centre point of a workpiece that
is 100

mm

wide.

In either absolute mode or incremental mode, once you have used Centre Find you can locate the centre
point by moving until the display is at zero.

If you are in absolute mode, remember that using Centre Find will set the datum to the centre point.

5.6  Datahold (Sleep)

Datahold allows you to disable the DPG2000 but retain power to the measurement transducers and the
memory circuits.  You can use Datahold to prevent unauthorised or accidental use of the DPG2000 whilst
unattended.

To select Datahold, press the concealed key located under the "

ne

" of the "newall" logo (See Figure 1.3).

While the DPG2000 has been set to Datahold, the keypad will not function and the displays will be blank. 
If the machine axis is moved, "

DISPLACD

" (displaced) will appear in the display window.  The DPG2000 will

record all transducer movement and will update the display once Datahold is cancelled.  If a key is pressed,
"

TOUCHED

" (touched) will appear in the display to alert the operator that data entry has been attempted. 

To cancel datahold, press the concealed key located under the "

ne

" of the "newall" logo.

5.7  Selecting An Axis Resolution

The resolution to which an axis position is displayed, can be selected by pressing the 

[ res ] 

key.  This will

display the current selection for all axes.

To alter an axis resolution select that axis by pressing either 

[ Xo ] [ Yo ] 

or

[ Zo ]

.  The resolution can then

be changed by pressing the 

∧∧

and

∨∨

keys.  Once the desired resolution is displayed press 

[ ent ]

.

If you make a mistake you can revert to the previous settings by pressing the

[ ce ] 

key

.
