Half Function / Centre Find
Digifind / Reference Function
The DP700 has a dedicated key to half the value in
any axis. This is done by initiating the half mode and
selecting the required axis. This can be seen in the
example on the right.

Standard Functions
The DP700 comes equipped with Digifind, a feature unique to Newall digital readout
products. Digifind eliminates the risk of losing your position and datum Set-Up.With Digifind,
precise Set-Up of a workpiece is carried out only one time.
When the DP700 is powered on, it displays the position at power off, compensated for any
movement of a Spherosyn transducer up to 0.2500" (6mm) and a Microsyn encoder up to
0.1000" (2.5mm) in either direction since the unit was last used. If the machine has moved
beyond 0.2500" (6mm) - Spherosyn [0.1000" (2.5mm) - Microsyn], Digifind allows a
quick means to find the datum if lost.

The original datum is reset
A mark must be made on both a stationary part and moving part of the machine.The marks
must be aligned and will serve as the machine "home" position.
The mark must be indelible, and it must allow the operator to move the machine to within a
0.2500" (6 mm) - Spherosyn [0.1000" (2.5mm) - Microsyn ] band around the
mark at any time. Alternatively, you can use a convenient reference point on the workpiece
If datum is lost at anytime it is possible to “Find” the datum again. Position the machine to
within the 6mm (0.2500”) band for Spherosyn and 2.5mm (0.1000”) band for Microsyn. “Find”
the reference.
As a fail safe, Digifind can ‘find’ the last datum or absolute zero set.
Position the machine to within the 6mm (0.2500”) band for Spherosyn and 2.5mm (0.1000”)
band for Microsyn. “Find” the reference.
