Page 5 Location & Mounting The QC200 must be placed or mounted on a stable, reliable surface. If the QC200 should fall, it could become seriously damaged and more importantly could cause injuries to the user. For mounting instructions, refer to the Getting Started section of Chapter 3: Operation, for the mounting bolt hole pattern.
Page 6 Backup Battery Charging The QC200 utilizes an internal battery to maintain system configuration set- tings during power interruptions. A battery circuit charges this backup battery during periods of normal operation. When the QC200 is used on a daily basis, the backup battery will be adequately charged to maintain configuration settings during power outages.

Page 22 The user interface retains many functions and features familiar to users of the Quadra-Chek 2000 and other Metronics products. In addition, more informa- ® tion is given to the operator via the graphic LCD display. Data is clearly pre- sented on one screen, eliminating the need to page or scroll for information.
Page 23 Quadra-Chek ® QC200 Use the front panel keys to perform standard inspection tasks. Select measure- ment functions, change operation and display modes, enter numeric data, zero axes, turn the LCD display on/off, or send data to a printer or computer with the press of a button.
Page 24 Chapter 1 Overview All front panel keys (except fast track keys) provide tactile sensory feedback. Additionally, supervisors can configure keys to provide audio feedback. The QC200 is equipped with a speaker and external speaker jack. Adjust speaker volume to suit the operating environment or plug a headset into the speaker jack. Transmit measurement data to a computer over the RS-232 port connection, or to a printer over the parallel or RS-232 port.

Page 33 Quadra-Chek ® QC200 Skewing the Part Accurate measurements require the part to be perfectly aligned on the coordi- nate measuring system. An imperfectly aligned part yields inaccurate measure- ments. Use the skew function to convert machine coordinates to part coordi- nates and compensate for part misalignment.
Page 34 Chapter 2 Quick-Start Demonstration Step 3 Press the enter key. Step 4 Probe two more points along the line as shown. Press the enter key after each point. Step 5 Press the finish key.
Page 35 Quadra-Chek ® QC200 The skew data screen is displayed and the skew is added to the feature list. The small skew icons displayed next to the X and Y axes indicate that the part is mechanically misaligned. An electronic alignment is applied to the skew line to compensate for the part skew.
Page 36 Chapter 2 Quick-Start Demonstration Set the Datum All measurements are relative to the datum. The datum is the zero point or origin of the coordinate system. Establish a datum once the part is skewed. The simplest way to establish a datum is to zero the X and Y axes on a point. In the example below, the skew line and a second line are used to construct a point.

For example, to measure a circle press the circle key, probe a minimum of three points, and press the finish key.
Page 88 Chapter 3 Operation Measuring points Points are the simplest features to probe. Only one point is required to define the location. A maximum of two points can be probed to measure a single point. The QC200 averages the points to produce the resulting point feature. To measure a point Step 1 Press the point key.

A minimum of two points (per leg) is required. Use more points for greater accuracy. When more than two points are probed on any line, a best-fit algorithm determines the location of the line and a form (F ) value is calculated the line.

Page 109 Quadra-Chek ® QC200 Changing feature types Occasionally, measure magic produces a different feature than the user intends. This is usually the result of unevenly spaced points. For example, measure magic might recognize three points but not be able to tell if the user intended a line or a circle.

Page 111 Quadra-Chek ® QC200 Creating Features It is sometimes useful to create features that are not found on the part geometry. Created features are often used as reference points for inspection purposes. For example, a feature on a part might be referenced to a point off the part geometry. In that situation, the user needs to create the reference point.

Optical edge detection recognizes light-to-dark or dark- to-light edge crossings on projection-based measuring machines. Each time a light-to-dark (or dark-to-light) is detected the QC200 identifies a point. Manual edge detection Manual optical edge detection recognizes light-to-dark or dark-to-light edge transitions.

Page 324 Chapter 7 Setup Error Correction There are three error correction methods used with the QC200: • Linear error correction (LEC) • Segmented linear error correction (SLEC) • Non-linear error correction (NLEC). All QC200 models are equipped with LEC and SLEC. NLEC is sold as a separate option.
Page 325 Quadra-Chek ® QC200 Segmented linear error correction (SLEC) divides each axis into a number of user-defined segments. Each segment has one error correction coefficient to compensate for variation within the segment. Each axis is also offset (MZ reference) to account for the variation between the standard datum and machine zero.
Page 326 Chapter 7 Setup Non-linear error correction (NLEC) divides the entire measurement area into a grid. Each grid cell compensates for variation with its own error correction coefficient. Specify the nominal and measured X and Y coordinates from the standard dur- ing the setup process.

Page 337 Quadra-Chek ® QC200 Step 8 Press the clear soft key. Step 9 Press the clear all soft key. The following dialog box is displayed. Step 10 Press the yes soft key. Step 11 ensures that systems equipped with non-absolute reference marks al- ways cross the same reference marks during the machine zero process.
Page 338 Chapter 7 Setup Step 11 Move all axes to the most negative position. Steps 12 through 14 establish machine zero. Step 12 Use the power switch to turn off the QC200. Step 13 Turn on the QC200. Press any key when the startup screen is displayed. Step 14 Set machine zero according to the on screen prompt.

Page 343 Quadra-Chek ® QC200 The MZ offset value is automatically entered in the MZ offset field. Step 32 Press the finish key. Station 0 is now defined as the last known point on the X axis with no variation between standard and observed values. All subsequent stations should show some variation between standard and observed values.

The QC200 prompts the user to measure the remaining stations on the grid. Finish NLEC setup by moving the crosshair to the prompted station.
Page 352 Chapter 7 Setup Step 15 Highlight the NLEC field as shown. Step 16 Press the on soft key. Step 17 Press the finish key twice. NLEC station setup is complete. Up to 29 cells can be entered on each axis. The NLEC correction coefficient is applied to all subsequent measurements when turned on.
Page 353 Chapter 8 Reference Three non-collinear points are the minimum required to measure a circle. Up to 100 points can be probed during a circle measurement. Use more points for greater accuracy. Every point on a circle is weighted equally but the first three points are used to estimate the form.
Page 354 Chapter 8 Reference When more than 3 points are used, a rough edge can be measured with greater repeatability. When 3 points are probed on a circle, each point contributes approximately 33% to the result. When 100 are used, each point contributes only 1%.

Page 356 Chapter 8 Reference Best Fit Algorithms There are four basic algorithms used by the QC200 to determine the best geometrical form fit of measured features. When the QC200 measures a line it uses the first two points probed to estimate the form fit of the line. The first three points are used to estimate the form of a circle.
