Error Compensation
Direction
Radius / Diameter
SETUP, Radius / Diameter, Direction, Error Compensation C70 Digital Readout System
NOTES
The Diameter setting is
useful for lathes, and
other turning
applications, to display
diameter rather than
radius.
The Direction setting is
quite arbitrary. Set it to
whichever makes most
sense to the machine.
NB, Direction is
dependent on where the
scale is mounted
If Error Compensation is
applied, it is important
that is absolutely correct.
If it is not correct, errors
could be increased rather
than reduced.
After setting up the Error
Compensation, it is
advisable to check its
effect in normal
operation.
Segmented
Compensation need not
be over the entire scale
length.
It can be applied just to a
length of high
importance, or it can be
as small as one segment.
Newall Measurement Systems Ltd10
Selecting the Diameter setting causes the C70 to display double the actual movement on any axis.
There are two possible settings for each axis:
Radius
Diameter
• Press the Select Key next to the , or to cycle between the two settings for each axis.
The Direction setting allows you to match the C70 to the actual direction of travel of any axis.
There are two possible settings for each axis:
• Press the Select Key next to the , or to cycle between the two settings for each axis.
Errors can result from a number of sources, including machine wear. Where the degree of error increases
linearly along the length of travel of the scale, Linear Error Compensation should be applied. However,
where the errors are local to an area of travel, the Segmented Error Compensation should be applied.
There are three possible settings for each axis:
Off
Segmented Compensation
Linear Compensation
• Press the Select Key next to the , or to cycle between the three settings for each axis.
If one or more axes are set to Segmented Error Compensation, or Linear Error Compensation, then
the next setup option will be to configure the compensation for each of those axes.
• Press .
The middle display changes to .
Segmented Error Compensation
In this mode, the scale travel for each axis can be broken down into as many as 99 user-defined
segments, with each segment having its own correction factor. The correction factors are calculated by
the C70 by comparison against known, user-supplied standards.
• When power is applied, the display for any axis that is set to use Segmented Compensation
shows .
• If the machine has not been moved since the power was turned off, simply press , and the C70
will restore the last positions recorded.
• Alternatively, set each axis close to the Reference Point - to within:
6.3mm (0.25”) for a Spherosyn encoder or
2.5mm (0.1”) for a Microsyn encoder,
and press the Select Key next to the , or . The C70 will re-establish alignment with the
correction parameters.
Linear Error Compensation
In this mode, a single constant correction factor for each axis can be applied to all displayed
measurements. The correction factor is calculated by the user, and specified in parts per million (ppm).
Values between -9999 and +9999 are allowed.
See pages 11 and 12 for details
on using Linear and Segmented
Error Compensation

Segmented Error Compensation
SETUP, Segmented Error Compensation
NOTES
Up to 99 segments can
be defined per axis
To take advantage of
Segmented Error
Compensation, you will
need access to a high
accuracy standard, such
as a laser measuring
system.
Error Compensation
initially defaults to off,
with no points set.
If Error Compensation is
set to Off after
Correction Points have
been set, the data is
retained, but not applied.
When Segmented Error
Compensation is set to
On again, the data will
be re-applied.
This procedure must be
carried out in strict
sequence, and in full, to
be valid. There must be
no reversals in direction.
Pressing select key
at steps 1, 2 or 3, will

relative to the (Starting
Point).
Do not worry about the
direction of the standard
measurement. eg. 678.9

Newall Measurement Systems Ltd 11
If one or more axes are set to Segmented Error Compensation, then the following procedure should
be followed to configure the compensation for each of those axes.
Identification of Correction Parameters
The scale travel is broken down into a number of user-defined segments, each with its own correction
factor, measured against a high-accuracy standard. The following parameters need to be identified:
error
travel
Starting Point - zero
Correction Points
Reference Point
0
1
2
3
4
5
6
Each Correction Point is measured with respect to the Starting Point - zero - which is usually set close
to one end of the scale. The Reference Point can be set anywhere along the scale, and does not need
to coincide with either the absolute datum or any of the correction points. However, it may be convenient
to make the absolute datum and the reference point the same.
Setting the Correction Points
As you follow the steps below, it is essential to take the following precaution:
Always approach the Starting Point, Correction Points and Reference Point from the same
direction. If you do not, then the size of the tool or probe will render the measurement inaccurate.
• Set one or more axes to Segmented Compensation as described on page 10.
The display should show, .
• Press the Select Key next to the , or to enter the setup procedure for each axis to be
configured.
The display changes to .
1 Set the machine to the point you have chosen to the Starting Point, and zero the high-accuracy
standard at this point. Press .
2 The display changes to .
Set the machine to the point you have chosen to be Correction Point 1. Press .
3 The display changes to .
Enter the distance from the Starting Point, as measured by the standard.
For Example: Press to enter a Correction Point of 678.9.
The C70 will calculate and display the correction factor for this point.
• Press to go to the next point.
Repeat steps 2 and 3 for each Correction Point.
When all correction points have been entered, press .
4 The display changes to .
Set the machine to the point you have chosen as the Reference Point. Press .
5 The display returns to .
If required, press the Select Key next to , or to enter the setup procedure for another

A single constant correction factor for each axis is applied to all displayed measurements.
If one or more axes are set to Linear Error Compensation, then the following procedure should be
followed to configure the compensation for each of those axes.
Calculating the Correction Factor
As you follow the steps below, it is essential to take the following precaution:
Either: Use a stepped standard, and approach each edge from the same direction.
Or: If you must approach each edge from opposite directions, then subtract the width of
the tool or measuring probe from the value displayed on the C70.
For Example: To check the scale against a standard which is exactly 500mm wide:
• Set the tool or proble to one edge of the standard, and press the Select Key for the axis to be
corrected.
The display shows .
• Set the tool or probe to the other edge of the standard.
The display shows , .
• Calculate the correction factor:
error = 500.000 - 499.8 = 0.2mm
Correction Factor = = x 1,000,000 = +400 ppm (parts per million)
This value displayed on the C80 needs to be increased to match the standard, so this is a positive
correction factor. If the display had shown 500.2 for the same standard, the correction factor
would be negative -400 ppm.
Setting the Correction Factor
• Set one or more axes to Linear Error Compensation as described on page 10
The display should show, .
• Press the Select Key next to the , or to enter the setup procedure for each axis to be
configured.
The display shows , or a previously entered value.
• For Example: Press to enter a Correction Factor of -400 ppm.
• Press again.
The display returns to .
If required, press the Select Key next to the , or to enter the setup procedure for
another axis.

• The C70 may be in Sleep Mode. Press .
• Check that the power supply is correctly connected to a
working mains outlet.
• Check that the power supply cables are not damaged.
• Check that the power supply voltage is 19Vdc ±10%.
• Disconnect all encoder cables. A defective encoder can
prevent the C70 from working.
• Check power supply lead on rear of C70 display to ensure
that is it illuminated
• This suggests either that the supply voltage is too low, or
that the power supply or mains supply has an intermittent
fault.
• Check that the power supply voltage is 19Vdc ±10%.
• Check that all connections are sound.
• This suggests that there may be a poor earth (ground)
connection.
• Both the C70 , and the machine on which it is installed,
must have proper earth (ground) connections. (see page 3)
• There may be a problem with the encoder (see below).
• This indicates that the unit is not receiving a proper signal
from the encoder.
• Check that the encoder connections are sound.
• Check that there is no damage to the connectors or to the
encoder.
• Switch the C70 off and back on again.
• Swap the encoder to another axis to confirm whether the
encoder or the C70 is at fault (see tip).
• Disconnect the C70 from it’s power supply, wait 15
seconds and then reconnect.
• Check Encoder Type to ensure correct selection.
• Check the Radius / Diameter setting. The Diameter setting
will cause the axis to read double.
• Check Error Compensation factors.
• If using Segmented Error Compensation, verify the datum
position.
• Swap the encoder to another axis to confirm whether the
encoder or the C70 is at fault (see tip).
• Check that there is no damage to the encoder or its cable.
• Check that the encoder is fixed firmly and aligned correctly,
as described in the Spherosyn / Microsyn Installation
manual.
• Check that there is no binding on the scale. With the scale
brackets slightly loosened, you should be able to slide the
scale back and forth with minimal resistance.
• If you have a Spherosyn scale, check that the scale is not
bent, by removing it and rolling it on a flat surface.
