Safety & Maintenance Considerations

General 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 guide and the rules of a company using this system, the more stringent rules should take precedence.

Safety information is also included on the next page and in Chapter 2: Installation.

WARNINGS Disconnect the QC-300 from power before cleaning.

The QC-300 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. The use of accessories that remove the third grounded connection such as a 2-wire power plug adapter create a safety hazard and should not be permitted. If a 3-wire grounded outlet is not available, ask your electrician to provide one.

DANGEROUS VOLTAGE

Do not open the enclosure unless you are a qualified service person approved by

Metronics, Inc., and never open the enclosure while power is connected. There are no

user-serviceable components or assemblies inside. Refer servicing to qualified service

personnel.

General Maintenance

Disconnect the QC-300 from power 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 QC-300 has been dropped or the exterior has been damaged

• The QC-300 exhibits degraded performance or indicates a need for service some other way

Cleaning the enclosure

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. Instructions for cleaning the touch screen are different and are given below.

Cleaning the touch screen

The touch screen should be cleaned as described below to prevent scratching or wearing the screen surface and to prevent liquids from leaking into the enclosure.

Use only a soft, lint-free cloth dampened with water for cleaning the touch screen. Never use abrasive cloths or paper towels. Never use abrasive cleaners, and never use detergents or solvents. Only dampen the cloth, do not use a cleaning cloth that is dripping wet. Never spray the screen.

If the screen is badly soiled, the cloth can be dampened with a 50:50 mixture of isopropyl alcohol and water. Remember, only dampen the cloth, do not use a cleaning cloth that is dripping wet, and never spray the screen.

QC-300 Series User’s Guide

Chapter 1: Overview

The Quadra-Chek 300 series is a family of advanced digital readout systems for performing 2, 3 and 4 axis measurements at very high levels of precision and accuracy. Dimensional inspection of components can be made using toolmaker’s microscopes and video measurement systems as part of in-line production activities or final quality inspection.

Feature points are entered manually using crosshairs or video edge detection, or automatically using the multiple video edge detection probe. Feature type can automatically be determined by the system when using Measure Magic. Part level and skew compensation can be performed on misaligned parts prior to measurements that eliminates the need for time-consuming fixturing.

Sequences of key-presses used to perform measurements can be recorded and stored as programs. These programs can be replayed later to perform complete measurement sequences. Sequences can be as simple as measuring a line, or can be expanded to include skew adjustment, datuming, the measurement of multiple features, tolerancing and printing reports of measurement results. Programs can include the CNC motion control option to fully automate program execution, increase thoughput and simplify operator tasks.

Overview

The intuitive interface will be familiar to users of the QC-200 and other Metronics digital readouts. Operators will find the QC-300 easy to understand and use thanks to the large color touch screen LCD display.

The color LCD displays alphanumeric and graphic information for the current measurement, part features and measurement data clearly on one screen, eliminating the need to page or scroll for information.

Touch screen controls select the feature to be measured, change operating and display modes, zero axes, and configure setup parameters. Touch screen controls change to support measurementspecific functions displayed on the LCD screen.

QC-300 Series User’s Guide

Assembling the mounting stand

The QC-300 is secured to the swivel slots of the mounting stand by a shoulder screw, a cap screw and associated washers.

Assemble the QC-300 to the mounting stand as shown. Tighten the shoulder screw (1), and then tighten the cap screw (5) and washers (3 & 4) so that the QC-300 will be secure when adjusted to the desired tilt position.

Safety considerations

The QC-300 is completely enclosed and no hazardous outputs can come in contact with the user. Safety considerations are related to power connections and physical mounting.

WARNING If the QC-300 falls from its mounting location, serious personal injury or damage to the equipment can result.

Power cord and plug

Do not locate the power cord where it can be walked on or will create a tripping hazard. Connect the 3-wire power plug to only a 3-wire grounded outlet. Never connect 2-wire to 3-wire adapters to the power cord or remove the third ground wire to fit the plug into a 2-wire electrical outlet. Modifying or overriding the third-wire ground creates a safety hazard and should not be permitted.

DANGEROUS VOLTAGE Always disconnect the power cord from the source of AC power before unplugging it from the QC-300 power connector. The AC voltage available at electrical outlets is extremely dangerous and can cause serious injury or death.

Electrical wiring and connections

Perform regular inspections of all connections to the QC-300. Keep connections clean and tight. Locate cables away from moving objects. Do not create tripping hazards with power cords, input/output cables or other electrical wiring.

Use shielded cables to connect to the serial RS-232 port. Make certain that cables are properly terminated and firmly connected on both ends.

Safety, Power and Encoders

Location and mounting

Rest the QC-300 on a flat, stable surface, or bolt it to a stable surface from the bottom using four 10/32 screws fastened in the pattern shown at the right.

Power surge suppressor

Connect the QC-300 to power through a high-quality power surge suppressor. Surge suppressors limit the amplitude of potentially damaging power line transients caused by electrical machinery or lightning. When a surge suppressor is not used, power line transients can corrupt system memory or damage circuits.

Installation

Connecting axis encoders

Axis encoders are attached to interface connectors on the rear of the QC-300. Many encoder interfaces are available to match the wide variety of encoders that can be used with the QC-300.
