ND 2100G panel keys

Panel keys are used to initiate feature measurements, apply tolerances, send reports of measurement results and configure operational parameters.

Panel function key

Panel key

Soft keys: Functions change in support of the activities displayed on the LCD.

Dimension keys: Can be assigned one of six hot key functions for use when DRO screen is displayed. When graph, bar value or data screens are displayed, dimension keys are used to display values for single dimensions or a smaller group of dimensions.

Command keys: Control measurement and data entry

processes.

cancel quit

Arrow cursor keys: Used to scroll through lists and navigate menus and setup screen data fields.

Fast track keys: Two programmable fast track keys are used to perform frequently used functions. These keys can easily be located by touch without taking your eyes off the part. Users can program either fast track key as described later in the Hotkeys portion of Chapter 2: Installation, Setup and Specifications.

Panel key

Numeric keypad: Used to enter numeric data. Additionally, the decimal point key and +/- key are used to adjust the contrast of the LCD display.

Send key: Used to transmit measurement results to a computer, USB printer or USB flash drive.

LCD On/Off key: Press the LCD on/off button to turn the LCD display off without removing power from the ND 2100G. Press the button a second time to restore the LCD display. Additionally, the LCD On/Off key can be used to clear channel calibrations, delete data stored for a single part or delete data stored for all parts.

Information contained in this manual

This User's manual covers the operation, installation, setup and specifications of the ND 2100G. Operating information is contained in chapter 1. Installation, setup instructions and specifications are contained in chapter 2.

Fonts used in this manual

The following fonts are used to indicate operator controls or to show emphasis:

Operator controls - soft keys and other panel keys are shown in upper case

Emphasis - Items of special interest or concepts that are emphasized to the user are shown in bold type

Showing sequences of key presses

The ND 2100G user performs sequences of soft key and panel key presses to measure part features and complete other tasks. These sequences are indicated using text as shown in the following example:

Press the MENU... soft key, press the DATUM... soft key and then press the MASTER soft key is sometimes abbreviated as:

Press MENU/DATUM/MASTER

Symbols within notes

Notes are marked with symbols on the left indicating the type, or potential severity of the information.

General Information

This is additional or supplementary information about an activity or concept.

Warning

This warns of a situation or condition that could lead to measurement errors, equipment malfunction or equipment damage. Do not proceed until the message is read and understood.

Caution - Risk of electric shock

This warns of a situation or condition that could lead to electrical shock and to personal injury or death. Do not proceed until the message is read and understood.

Preface

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

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

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.

The numeric keypad is used primarily for numeric data entry. The decimal point key and +/- key can also be used to increase or decrease the LCD screen contrast when a decimal point or +/- input are not expected by the system as part of a data entry process. The screen contrast setting will be saved when the system is powered down and used as the default contrast setting the next time the system is turned on.

22	1 Operation

Dimension keys

Dimension keys can be assigned one of six hot key functions for use when the DRO screen is displayed. When graph, bar value and data screens are displayed, the dimension keys are used to display values for single dimensions or a smaller group of dimensions.

Dimension keys	Function
	Pressing a dimension key in the:
	DRO screen: performs the function
	assigned in the hotkey setup
	screen. By default no hotkey
	function is assigned until the user
	makes the assignment
	Graph screens: displays a single
	graph for the corresponding
	dimension
	Bar screens: Displays a single bar
	showing current values for the
	corresponding dimension
	Data screens: displays a single data
	table of stored values for the
	corresponding dimension

Hot key assignments are discussed in detail on page 141.

Soft keys Function

Soft keys initiate functions that are labeled above the keys at the bottom of the LCD screen. As different system functions are selected, the soft key labels change in support of those functions.

Pressing the dimension A key in a graph screen selects the A graph for display.

1.3 Panel key descriptions

Pressing the VIEW... soft key changes soft key labels to show five screen viewing options, graph, histogram, bar, data and DRO.

Pressing the VIEW... soft key causes soft key labels to change, offering five options for viewing data.

When viewing graphs of stored data, current value bars or tables of stored data, pressing a different soft key changes to the view indicated by the soft key label.

Pressing the DATA... soft key when viewing bars causes the dimension data table to be displayed.

24	1 Operation

Pressing the currently highlighted soft key alternates between singledimension and multiple-dimensions displays.

Pressing the BAR... soft key when viewing multiple-dimensions causes the currently selected dimension to be displayed by itself.

The left most soft keys can be designated hotkeys to provide quick access to commonly used functions when the home screen is displayed. Hot key assignments are discussed in detail in Chapter 2: Installation, Setup and Specifications.
