Precautions
For your protection, please read these safety instructions completely before operating the
appliance.
Selection of mains voltage●
The Digital readout unit is supplied for 100V 230V, 50Hz/60Hz, 20W max operation.～
Instructions prior to activation of unit
1. Please ensure that the voltage rating corresponds to the mains supply prior to activation.
2. If this unit is to be operayed via an autotransformer from mains supply of higher voltage,
it must be ensured that the low end of the transformer is connected to the neutral wire
of mains.
The mains connector may only be inserted into a socket with earthing contact. The protective●
effect should not be cancelled by an extension lead without an earthed conductor.
Any interruption of the earthed conductor either inside or outside of the unit or
disconnection of the earthed conductor can render the equipment potentially dangerous.
Any intentional break is not permissible.
Please install the Linear Encoder finish after that switch on the Digital Readout Unit. If●
switches on Digital Readout Unit before install the Linear Encoder not finished yet. This may
cause electronic parts burnt away of the Linear Encoder.
Do not use the instrument in an extremely hot or humid place.●
Do not use the instrument near strong magnetic or magnetic field noise place. This is the●
main reason that causes instrument error working.
Wipe the Digital readout unit surface with a soft cloth to remove fingerprints, dust, etc.●
Clean the Digital readout unit surface with a soft cloth slightly moistened with Neutral●
purger to remove serious dirt.
Do not use the organic solvent products such as oil, diesel fuel, kerosene, alcohol,etc clean●
the Digital readout unit.
Do not use the Air guns fanned Digital readout unit and Linear Encoder accessories to let●
grease, dust or bits get into the Digital readout unit. This may cause the system working
unstable and malfunction.

INC
RD-11M ABSprovides two sets of basic coordinate display, they are (absolute)
and (incremental) displays.INC
During machining operations, the operator can store the work piece datum ( zero
position ) in coordinate, then switch to coordinate to continue machiningABS INC
operations.
The operator is then free to zero the axes or preset any dimensions into any
axis in coordinate for relative position machining. The work piece datumINC
( work piece zero position ) is still retained in coordinate by the .ABS RD-11M
Operator can then toggle between (absolute) and (incremental)ABS INC
coordinates without losing the work piece datum ( work piece zero position ).
Purpose :
Example 1 : Currently in display coordinate, to switch to display coordinateABS INC
Example 2 : Currently in display coordinate, to switch to display coordinateINC ABS

Purpose : RD-11M provides the centre-find function by halving the current display coordinate, so that the
zero point of the work piece is located at the centre of the work piece.
To set the X Axis zero point at the centre of the work piece.
Example :
Step 1 : Locate the edge finder at one end of the work piece, then zero the X Axis.
Step 2 : Locate the edge finder at the opposite
end of the work piece.
Step 3 : Then half the display coordinate using centre-find function as per follows:
Now the X Axis zero point ( 0.000 ) is located at the X centre of the work piece.

During the daily machining process, it is very common that the machining cannot
be completed within one working shift, and hence the DRO has to be switched
off, or less commonly, a power failure occurs whilst machining which leads to
loss of the work piece datum ( work piece zero position ). The re-establishment
of work piece datum using edge finder or other method inevitably introduces
machining inaccuracies, because it is not possible to re-establish the work piece
datum exactly at the previous position.
To allow the recovery of work piece datum very accurately, with no need to
re-establish the work piece datum using an edge finder or other methods, every
transducer has a reference point location to provide a datum point memory function.
The working principal of the ref datum memory function is as follows.
-There are a permanent and fixed mark (position) on the transducer,
normally called mark or point..ref ref
Since this point position is permanent and fixed, it will never change orref
disappear when the DRO system is switched off. Therefore, we simply need to
store the distance between the point and the work piece datum ( zeroref
position ) in DRO's memory. Then, in case of the power failure or the RD-11M being
switched off, we can recover the work piece datum ( zero position ) by presetting
the display zero position as the stored distance from the point.ref
to store the X axis work datum
function :
Example :
RD-11M provides one of the most easy-to-use datum memory function.ref
There is no need to store the relative distance between the mark and your work datumref
zero into the ,RD-11M whenever you alter the zero position of coordinate, such as by zeroing,ABS
centre find, coordinate preset or etc.., will automatically store the relative distanceRD-11M
between zero and the mark location into 's memory.ABS RD-11Mref
In daily operation, operator simply needs to locate the mark position whenever they switch onref
the to let it know where the mark position is, then will automatically do theRD-11M RD-11Mref
work datum storage on its' own . In the case of a power failure or the being switched off,RD-11M
the operator can recover the work piece datum easily by using the procedure.RECALL 0

whenever the operator alter the zero position, such as zeroing, centre find,ABS

Therefore, the needs to store the mark position prior to any machiningRD-11M ref
operation. So that the loss of the work piece datum ( zero position ) is avoided during
any accidential or unexpected events, such as power failure or etc.. it is recommend that

Purpose : Most cabinet on the market provide just two set of work co-ordinates - . It wasDRO ABS/INC
found that was inadequate and inconvenient to use, and, particularly in the case ofABS/INC
complex machining or repetitive work, which needed more than just two sets of working
co-ordinates.
operation has the following shortfalls :ABS / INC
- In much machining work, the work-piece machining dimensions are derived from more than
two datums, therefore, the operator has to switch between and to set up theABS INC
machining datums time after time. This process is very time consuming and prone to error.
- In the case of batch machining of repetitive work, the operator has to set up and calculate
all the machining positions time after time.
RD-11M 199 sdm ABS/INC SdMprovides a subdatum ( ) memory to cope with the shortfalls of .
function does not just simply provide sets of co-ordinates, it is specially designed to provide much199 INC
more convenient features for the operator to cope with repetitive work.
The difference between and is as follows:.INC SdM
1. is independent of and will not follow any change in zero point. AllINC ABS ABS sdm
co-ordinates are relative to the coordinates, so, all positions will move togetherABS SDM
when the zero position changes.ABS
2. All relative distance data to can be entered directly into memory using theSdM ABS RD-11M
keypad. No need for any additional calculations.
SdM application in a work piece that has more
that one datum.
Operator can store all the work subdatums in
RD-11M's memory as per follows.

by pressing key

SdM application on the repetitive batch machining of
parts
Because all sdm subdatums (0.000) are relative to
ABS zero, so, for any repeative work, the
operator just needs to set up the first work piece zero
at ABS and store the machining position in subdatum
zero.
For anymore repeative parts, just set up the 2nd, 3rd..
work piece zero at ABS, then all the machining
positions will reappear

In a case where many subdatum ( sdm ) points need to be set up,the operator will find that the method of
direct keying in the of SdM zero position co-ordinates ( co-ordinate relative to ABS zero )
is much quicker and less prone to error.
Set up the work piece datum ( ZERO) at ABS co-ordinate, then move the tool located at the work piece datum
( ABS zero point )and directly key in all subdatum point co-ordinates ( the relative position to ABS zero ) using
the keypad.
Step 1 : Set up the work piece datum in ABS coordinate
Step 3 : Set up the subdatum point 2 ( sdm 2 )
Step 2 : Set up the subdatum point 1 ( sdm 1 )
When you enter the sdm co-ordinate
into the RD-11M, the co-ordinates
displayed will indicate a negative
sign.
This is correct because your tool is
now located at zero position at ABS
coordinate. If you calculate from
the sdm co-ordinates, the tool is
at a negative value.
