Conventions & Terms
QC-300 refers to any of the QC-300 series of instruments. System refers to the QC-300 and the measuring
devices connected to it.
Icons
This guide uses the following icons to highlight information:
WARNINGS
The raised hand icon warns of a situation or condition that can lead to personal injury
or death. Do not proceed until the warning is read and thoroughly understood.
DANGEROUS VOLTAGE
The lightning icon warns of the presence of an uninsulated dangerous voltage within
the product enclosure that might be of sufficient magnetude to cause serious shocks or
death. 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.
CAUTIONS & IMPORTANT INFORMATION
The exclamation point icon indicates important information regarding equipment
operation or maintentance, or a situation or condition that can lead to equipment
malfunction or damage. Do not proceed until the information is read and thoroughly
understood.
NOTE
The note icon indicates additional or supplementary information about an activity or
concept.
Safety & Maintenance Considerations
General safety precautions must be followed when operating the system. Failure to observe these precau-
tions 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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.

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 comparator or toolmaker’s microscope systems as part of in-line production activities or final
quality inspection.
Feature points are entered using crosshairs or (optional) optical edge detection. Feature type can automati-
cally be determined by the system using Measure Magic. Levelandskewcompensationcanbeperformed
on misaligned parts prior to measurements to eliminate 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.
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 under-
stand and use thanks to the large color touch
screenLCDdisplay.
The color LCD displays alphanumeric
and graphic information for the current
measurement, part features and mea-
surement 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 measurement-specific functions displayed on
theLCDscreen.

frequently used functions programmed by the user. All front panel keys provide tactile sensory feedback,
and key-press operations can be configured to generate an audible sound.
Speaker and external speaker jack outputs are provided that can be adjusted for quiet or noisy environ-
ments. Ear phones can be plugged into the external speaker jack to facilitate silent operation in quiet
environments.
