The surfaces of optical parts should be kept clean. They should not
be touched with hands. If any dirt, oil fleck or dust are found on the
surfaces, they should be removed with soft brushes, or they should
be removed with clean linen or lens paper soaked in methyl benzol
or in a mixture of alcohol and ether. Try to rub the optical surfaces as
less as possible.
The instrument should not be operated with a big force. All bare
metal surfaces of the instrument and the accessories should be
wiped clean and coated with protection grease after operation.
When work-piece with larger diameter is to be measured, take down
objectives 50x and 100x and place them into the accessory box.
Objectives, guides and condenser have higher precision. They
should not be dismantled optionally. If it is necessary, they should be
sent to the specialized factories for repair.

co-ordinates. Also enter the +/- values for each nominal
value.
Limits allow the user to set upper and lower limits on a value.
For example, a nominal value of 10.3250 might have an upper
limit of 10.3260 and a lower limit of 10.3240. For example, if a
part drawing gives a +/- tolerance of 0.005, simply enter 0.005 in
the plus and minus fields.
After set press { } key. The result of tolerance Pass or Fail is
shown for the selected feature.
Use the same way to set Tolerance for line, angle, circle and
distance.

Maintenance
1The projector is a kind of precision optical instrument. Attention
should be paid to its maintenance so as to guarantee the precision
and lengthen life of the instrument. The instrument should be
installed in a clean room, the temperature of which should be
maintained at 20° ± 5℃. The relative humidity of the room should
not exceed 60﹪ so as to prevent the optical parts and reflecting
mirror from molding and to keep the high quality of the image.

Cross hair and mounted edge detector probe may have physical
position offsets, hence to obtain accurate results; we must do the
cross calibration process for every magnifications.
If we don’t execute cross cal, and if we probe a circle by cross
hair and by edge detector, in both cases, we will get diameter
equal but centre coordinates will be different.
In this mode the user has to probe a circle using Edge detector
and again probe the same circle using cross hair. The result of
Cross calibration is displayed as shown below.
Save the changes and exit Edge detector calibration.

Measurements using Edge Detector mode:
For performing feature measurements using Edge detector,
select Edge mode by pressing { } soft key in DRO mode.
Now press any feature key and probe points using Edge detector.
Rest procedure remains same as explained in Geometric Feature
Measurement chapter.

Tolerance
Tolerance helps users maximize productivity. A tolerance is an
acceptable deviation from the nominal specification of a part. For
example, a pin might have a nominal diameter of 5.000 mm. Without
tolerance, only pins with a diameter of .5.000 mm are acceptable.
This means that pins that measure 4.999 mm or 5.001 must be
rejected. With tolerance an acceptable deviation from the nominal
specification is defined. For example, the diameter of 5.000 mm
might have a tolerance of +/- .05. This means that pins as small as
4.950 mm and as large as 5.050 mm are acceptable.

Screen Gain (<10000) – This sets the gain of the amplifier. The
gain depends on the magnification and the light source. Adjust
this such that the Screen intensity on light region displays counts
above 3000 counts to 4000. In case of higher magnifications
where the counts doesn't reach the required value even if the gain
is set to 100, then minimum of 2000 counts should be ensured for
good results. Press { }key to set the gain value.
Now bring the screen sensor in the light region and press { }
key.
Now move the screen sensor in to dark region. Press { } k ey
to teach dark to the DRO. Here note that the counts in the dark
region are less than that in the light region.
NOTE: Every time the light intensity changes it is recommended
to teach light and dark region to the D RO for p roper
measurements. No need to change the gain of the system.
Now perform Edge calibration. In this mode the selection is
provided for bore or shaft measurements. If the user wants to
check bore jobs he has to perform bore calibration using F.O.
Edge detection prior to measurements.
NOTE: It is mandatory to calibrate the type of job either bore or
shaft prior to measurements using F.O. Edge detection.
Now probe the circle as per procedure explained earlier. Press
[ ] key to complete the measurement. Following screen is
displayed.
Now enter the standard diameter of the circle. The DRO will
calc ulate the calibration factor and apply it during the
measurements by Edge detector.

Linear Error Correction(L.Comp/LEC):
In this mode place a slip gauge of standard length on the X-Y
table. Align it properly for calibration.
Now bring cross hair to one of the edge of slip. Reset the axis.
Now move the crosshair to other end of the slip and note down the
display reading. Now enter the Linear compensation mode for
that axis by selecting {L. Comp} at “Apply Comp X Axis”.
Enter the standard value as the slip value and the observed value
using the numeric keys on keyboard. Press [Enter] to confirm.
The DRO will calculate the linear calibration factor and stores into
its memory. The user can edit this calibration factor by changing
the observed value or the standard value in the same mode. After
doing this you may check the axis performance by measuring
different slips and confirm the accuracy.
1
Segmented Error Correction (S.Comp / SLEC):
Segmented Linear Error Compensation (SLEC) is used when the
results of the comparison with a reference standard shows non-
linear error. In SLEC the entire axis travel is divided into user
defined segments. The error in each segment is compensated
with a single correction factor. Each correction point is measured
with respect to the starting point. This starting point is usually set
close to the end of the scale. This starting point can coincide with
the absolute datum point or Home reference.

Edge Detector(For ISP-A1000E)
Optical Edge detection can be used with DRO to increase throughput
rates, increase measurement accuracy, improve measurement
consistency and reduce operator fatigue. In this mode after selecting
a point the user is not required to press [ ] key but the point is
probed automatically as the sensor travels from either Light to Dark
or Dark to Light region.

Fiber-optic cables cannot be bent to a radius less than one inch
without degrading performance. Be careful to prevent bending or
pinching the cables.
Fiber-optic cables cannot be exposed to temperature higher than
70 degrees Celsius without degrading performance.
Use of C.V.T. (Constant Voltage Transformer) is recommended
for better performance of edge detection circuit as fluctuations
may cause intensity variations on the screen.
Edge Detector Calibration:
Before using Edge detector for measurements it is necessary to
calibrate it. It is necessary to calibrate the DRO prior to this
calibration. Mount the demonstration slide on to the X-Y table. In

Grid Calibration:
It is also referred to as Non Linear Error correction (NLEC).
In this the entire measurement area is divided in to a grid. Each
grid cell compensates for variation with its own error correction
coefficient. It is mandatory to set the machine reference for each
axis before NLEC.
Specify the nominal and measured X and Y coordinates from the
standard during the setup process. NLEC requires a repeatable
machine zero defined on startup.
3
The changes will get saved in the memory and are applied.
The user will have to perform machine reference on every power
ON if SLEC is selected for an axis.
Machine Reference
Here the Machine reference can be set forthe selected axis. The
standard reference output from the encoder is used for referencing.
This is used only in case Segmented Linear compensation is to
selected.

Calibration Procedure:
Keep the encoder position near to the desired reference on the
encoder.
Press { }key in “Machin e Ref . ” in axis setti n g s .
“Homing”Message is shown on the screen.
Pass the reference mark on the encoder. Here the DRO will reset
the axis on the reference mark.
Go to the machine reference position and press { }key.
Normally this is the start position of the segnments
Calibration procedure for Z (Angular) Axis
Manual Calibration of Z axis:
User can calibrate angular axis manually by pressing manual
softkey. Display value will show counts of respective rotation.
User will enter angle of rotation in seconds. Now user can
calculate calibration factor by pressing calc softkey.After
calibration press [Enter] to save the calibration factor. Press
[Cancel] if the user wishes to exit without saving.
1
Auto Calibration of Z axis:
User can calibrate the angular axis automatically by selecting the
{ }key. The DRO waits for two complete rotations of the
encoder and then calculates the calibration factor by calculating
the counts between the two reference marks on the encoder. To
calibrate the Z axis using auto mode requires only one condition
that it must have only one reference mark for each rotation.

Construction:
Feature construction is the process of combining existing
features to generate a new feature.
New feature can be constructed using existing features that were
measured or constructed.
The result of construction is displayed in the result window. Also
the user can see the constructed feature graphically. Form is not
applicable to constructed features, apart from that these features
are same as any measured or probed feature.
Construction Procedure:
10
Press the desired feature which is to be constructed.


12
Angle Measurement:
Angles can be measured by probing points between two lines. In
this mode the DRO automatically prompts the user to measure
1st line and the 2nd line. Each line can be measured by probing
between 2 to 20 points. Accuracy of this measurement is
increased if more number of points are probed over greater
distances.
After probing both the lines the angle between them is
determined by using best fit algorithm.
The measured angle can be displayed in 4 ways. The user can
change the angle display using [ ] key of the 3rd axis. The four
angle measurement types are as shown below.


Similarly probe line 2 and press [ ] key. The angle result
screen will be displayed.

Wonder Measurement:
Wonder feature helps to minimize key presses during feature
measurement. Also it automatically detects which geometrical
shape has been probed. This feature can be activated once or
repeat.
8
15
Skewing the job is also possible from constructed features. The
result of constructed feature should a line, since skew is applied
on a probed line.
For example, if a line is constructed from a circle and a line. The
result line is the skewed line. And all the measurements are with
respect to this line.
If we press [ ] key in normal counting mode,. Now if we probe
the points (without pressing feature key), and press [ ] key,
the DRO will show the result of probed feature.
If we want to probe the feature again without pressing feature
key, we have to press [ ] key again.
A
A
If we press [ ] key twice, symbol will be displayed on the DRO
screen at right top corner. Now we can probe the features
repeatedly without pressing feature keys.
A
Pressing [ ] key will exit from Wonder feature.
In SETUP MODE, there is one option, to set “Relational
Parameter OFF” or “Relational Parameter ON”.
To detect an angle, two main things must be considered while
probing the points.
1) There are two limbs of angle and on both limbs; equal number
of points must be probed.
2) On either limb, at least three points must be probed.
A

13 14
Skewing the Job:
During measurement of any part for its dimensions, it is
necessary to perfectly align the part on the co-ordinate
measuring system. Any misalignment of part will result in
inaccurate measurements.
The part to be measured cannot be aligned exactly with co-
ordinate measuring system of machine. Therefore it is necessary
to skew the Job prior to measurement.
The skew function converts machine co-ordinates to part co-
ordinates by electronically compensating for part misalignment.
7
Note: As shown in the above figure, the part must be placed within
45 degrees of the machine’s co-ordinate system.
Procedure for skewing the job:
Press [ ] key. Following screen will be displayed.
Press [ ] key to complete skew measurement. The result
s c r e e n i s d i s p l a y e d a s s h o w n b e l o w. A n y f e a t u r e
measurement done henceforth will be with respect to skewed
co-ordinates. For indication of skew, the X and Y axis labels
are represented as shown below.
Now probe line which is to be skewed. Use standard
procedure for line measurement. Probing more points will
increase the accuracy of skew measurement.
A
Pressing [ ] key will exit from skew mode. The DRO will
prompt to cancel skew. Now on the DRO functions in normal
mode.
