Safety considerations

General accepted safety precautions must be followed when
operating the system. Failure to observe these precautions could
result in damage to the equipment, or injury to personnel. It is
understood that safety rules within individual companies vary. If a
conflict exists between the material contained in this manual and the
rules of a company using this system, the more stringent rules should
take precedence.

The ND 2100G is equipped with a 3-wire power plug that
includes a separate ground connection. Always connect
the power plug to a 3-wire grounded outlet. Use of 2-wire
power plug adapters or any other connection accessories
that remove the third grounded connection create a safety
hazard and should not be permitted.

Unplug the ND 2100G from the power outlet and seek the
assistance of a qualified service technician if:

 The power cord is frayed or damaged or the power plug

is damaged

 Liquid is spilled or splashed onto the enclosure
 The ND 2100G has been dropped or the exterior has

been damaged

 The ND 2100G exhibits degraded performance or

indicates a need for service some other way

ND 2100G channel inputs

The ND 2100G can be connected to the following channel
configurations.

 1, 4, or 8 single input channels
 Up to 16 networked RS-232 input channels
 Or combinations of single input channels and networked RS-232

input channels for a total of up to 16 channels

Software version

The software version is shown in the About setup screen discussed
later in chapter 2.

Cleaning

Use only a cloth dampened with water and a mild detergent for
cleaning the exterior surfaces. Never use abrasive cleaners, and never
use strong detergents or solvents. Only dampen the cloth, do not use
a cleaning cloth that is dripping wet.

Operation

1.1 ND 2100G Overview

Overview

The ND 2100G is an advanced digital readout system for performing
single or multiple gage measurements at very high levels of precision
and accuracy. Dimensional inspections of components are performed
using encoders or transducers as part of in-line production activities,
or final quality inspection. Measurements are conducted under
operator control, or are semi-automated and conducted in conjunction
with a fixtured gage system.

The ND 2100G is configured at the factory to support

 One, four or eight single-input channels, or
 Up to 16 multiplexed RS-232 input channels, or

1.1 ND 2100G Overview

 Combinations of single-input channels and multiplexed RS-232 input

channels for a total of up to 16 channels

Channel inputs can be algebraically combined or processed by
powerful math and control formulas to display dimensions such as
flatness, volume and runout. Formulas are created as part of the
ND 2100G setup using straightforward screen control and math
functions.

C1=28.846 mm Sum=C1+C2 Sum=12.820
C2=-16.026 mm Dif=C1-C2 Dif=44.872

Channel inputs are processed by formulas to display dimensions.

18 1 Operation

The intuitive user interface includes a large character color LCD for fast
and accurate measurement feedback. User interface screens include
a digital readout of current values, bar and dial position value
indicators, graphs of values, histograms of measurement statistics
and tables of measurement and of SPC data.

channel 2 falls outside a specified range, all base-channel (first 1, 4 or
8 channels) input values will be stored in a dedicated memory array,
otherwise samples will not be stored.

This sampling process continues until:

 The process is automatically completed after 50,000 sets of channel

positions have been stored

For the duration of the Fast3 function process, the
ND 2100G adopts an X-Y axis paradigm. Channel 1 is
referred to as the X-axis, and channel 2 as the Y-axis.

In the example shown, the channel 2 (Y-axis) input values exceed the
user-specified limits five times, but channel input values are stored
only twice when the channel 2 value exceeds the limits at a sample
point between intervals.

When the Fast3 function is successfully completed, the stored sets of
channel input values are processed by the ND 2100G dimension
formulas in the order that they were collected. The formula results are
then stored in the ND 2100G database. During the processing of
formulas, a percentage of completion will be displayed. Since up to
50,000 sets of channel input values can be collected and processed by
formulas, considerable time could be required to complete the
processing.

Since the values processed by formulas after Fast3 data
collection are contained in memory storage, no user
interaction is possible. For this reason functions that
require user interaction such as the Ask function must be
avoided in formulas when the Fast3 Extra menu function
is used.

If any key is pressed while the ND 2100G is processing

Establish a reference for the measurement

A measurement reference should be established prior to conducting
measurements. Measurement references can be established by
calibrating channels or presetting dimensions.

Select Part

An input calibration is applied to any parts that use that
channel in a formula. For example, a channel calibration
performed for channel 1 and part number 0 will also apply
to any other parts using channel 1.

Calibrating channels using the Master function

Channel calibrations are performed using the Master function. A
single-point calibration defines the reference value of the absolute
datum (D0) of an input channel. A full calibration defines the reference
value of the absolute datum, and the resolution of the channel input.

Since encoders have fixed resolutions based on etched scales or
some other permanent device characteristic, typically only a single
point is calibrated to define a reference position. Transducers such as
LVDT and Half-bridge devices do not have fixed resolutions. The use
of these devices requires calibrating both ends of the transducer’s
measurement range to derive resolution. Once a full calibration has
been performed, single-point calibrations can be performed as
required to define new measurement reference positions.

Calibration groups (G1, G2, G3...G18)

All calibration values shown on the screen are simultaneously applied
when the ENTER key is pressed. While this is acceptable in most
cases, some applications require entering a series of calibrations at
different times. The example shown here illustrates this difference.

When measuring runout at two points on a
rod, both channels are measuring a
common surface and can be calibrated
simultaneously. In this example, both
channels are calibrated to zero on the rod
surface in calibration group 1 (G1).
Completed calibrations are indicated by
filled circles at the right of the actual channel
values.

When measuring the low and high lifts of
two offset cams, simultaneous calibration
on the offset surfaces is not possible. First
one channel must be calibrated to zero on
the low surface of one cam, then after
turning the cam shaft 90 degrees, the
second channel must be calibrated to zero
on the low surface of the second cam.

The first calibration is performed in
calibration group 1 (G1), then the camshaft
is turned 90 degrees, and the second
calibration is performed in calibration group
2 (G2). By performing the calibrations in
different groups, the calibrations are made
independent. Completed calibrations are
indicated by filled circles at the right of the
actual channel values.

Calibrations of transducer resolution (Min-Max calibrations)

Transducers such as LVDT and half bridge devices do not have fixed
resolutions based on etched scales or other permanent device
characteristics. The use of these devices requires calibrating both
ends of the transducer range of measurement to derive transducer
resolution. Full transducer calibrations are performed periodically on a
schedule determined by your application using the Master function.
Full calibrations are performed only after performing the transducer
gain and null setup steps described in Chapter 2: Installation, Setup
and Specifications.

The Master type should be set to Min-Max in the Master
setup screen to perform a full transducer calibration. Refer
to "Master setup screen" on page 111.

Establishing a temporary dimension reference

Establishing a temporary dimension reference is useful when quick
point to point measurements are desired. The temporary reference is
only applied to the associated dimension, and only to the current part.
For example, a temporary reference established for dimension A and
part number 0 will not apply to any dimensions or to any other parts
that might include their own dimension A.

Temporary dimension references can be established for encoders and
transducers. Since only one point is used as a reference, transducer
resolution remains unchanged.

Dimension references can be zeroed or preset to specific values.

Zeroing a dimension reference

Dimensions can be zeroed at any time using the Datum/Zero function.
The zero reference is temporary in the sense that it uses the
incremental datum D1, and has no effect on the absolute datum D0.

Dynamically sampled measurements

The ND 2100G can be configured in the Formula setup screen to
sample input channels and retain the minimum and maximum values
of all samples for each channel. Typically a setup person specifies
dynamic measurements to evaluate rotational or curved surfaces and
will provide instructions describing how to conduct the
measurements. The ND 2100G operation is essentially the same for
all dynamic measurements.

Measurement results can be displayed as current values, in graphs or
in data tables using the screens described earlier in this chapter.
Please refer to the descriptions of Views on page 28.

Measurement results can also be printed or transmitted to a
computer. The data printed or transmitted is specified and formatted
in the setup screens described in Chapter 2: Installation, Setup and

Semi-automated measurements

Normally, measurements shown on the DRO screen are not stored in
the ND 2100G database until the user presses the ENTER key.
However, the ND 2100G can be configured in the Formula setup
screen to perform and store measurements automatically when the
gage is loaded with a new part.

Measurement results can also be printed or transmitted to a
computer. The data printed or transmitted is specified and formatted
in the setup screens described in Chapter 2: Installation, Setup and
Specifications.

In the example shown here, the flatness of a sheet is measured. The
measurement is performed and entered into the database a short time
after the gage is lowered to position the probes against the surface of
the sheet. The channels are reset for a new measurement when the
probes are lifted away from the sheet.

Typically, a setup person specifies semi-automated measurements to
increase the throughput of repetitive measurements, and will provide

2.3 Software setup

ND 2100G GAGE-CHEK 81

Formulas setup screen

The ND 2100G uses formulas to define and display dimensions based
on channel inputs.

These formulas are constructed by the user to display:

 One dimension based on one channel

ex. A=C1

 One dimension based on multiple channels

ex. A=C1+C2

 Multiple dimensions based on one channel

ex. A=C1

2.3 Software setup

B=2*pi*C1

 Multiple dimensions based on multiple channels

ex. A=C1

B=C2
C=C1*C2

Formulas can be constructed that display a channel as a dimension, or
that calculate a dimension from one or more channels using powerful
math, logic or other functions.

Dimension formulas are unique to the part they are created in. For
example, a dimension formula created in part 0 cannot be used in part

2. However, system dimensions are described later in this chapter and
can be used across all parts.

Refer to "Formulas" on page 163.

Formulas setup screen.

82 2 Installation and Specifications

Variables setup screen

Formulas use variables as symbols or names that represent values.
For example, in the expression:
C1+Var1()
Var1() is a variable, its value is flexible and is determined by operations

on a different formula line for the current part. Variables can represent
numeric constants, channel input values, dimension values or the
results of a wide variety of math operations.

Variables are important in formula creation because they enable users
to create flexible formulas. Rather than including data directly into a
formula, a user can use variables to represent the data. Then, when
the formula is executed, the variables are replaced with actual data.
This makes it possible for the same formula to process different sets
of data as conditions change.

The Variables setup screen allows the user to see the current value of
any of the 20 possible variables. Variables that are not defined
elsewhere by formulas can be set to constant values in this screen by
highlighting a variable field and entering the value. Variables that are
defined by formulas cannot be changed in the Variable setup screen.

Variables are unique to the part they were created in. For example, a
variable created in part 0 cannot be used in part 2. Global variables,
discussed later in this chapter, can be used across all parts.

Variable functions are defined in the Formula setup screen
on page 82. Formulas are explained in the Formulas
section on page 163.
