Safety and
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.
Although Metronics strongly recommends that you read all parts
of this guide, it is essential for reliable and safe operation to read
the first portions up to and including Chapter 2: Operation, prior
to operating the QC100.
Location and Mounting
Cleaning
Electrical
The QC100 must be placed or mounted on a stable, reliable surface. If the QC100 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 2:
Operation, for the mounting bolt hole pattern.
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.
Do not allow the power cord to be located such that it can be
walked on or create a tripping hazard.

General maintenanceUnplug the QC100 from the wall 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 QC100 has been dropped or the exterior has been damaged
• The QC100 exhibits degraded performance or indicates a
need for service some other way
Backup battery
charging
The QC100 utilizes an internal battery to maintain system configuration settings during power interruptions. A battery circuit
charges this backup battery during periods of normal operation.
When the QC100 is used on a daily basis, the backup battery will
be adequately charged to maintain configuration settings during
power outages. However, over extended periods of nonuse, the
battery might lose the charge necessary to maintain configuration settings. To keep the backup battery charged over extended
periods of nonuse, apply power to the QC100 and leave it turned
on for a minimum of 2 days each month.
FCC compliance
statement
FCC Rule NP15R Rev. 23, June, 1989
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used
in accordance with the instructions in this guide, may cause harmful
interference to radio communication. Operation of this equipment in a residential area is likely to cause harmful interference, in
which case the user will be required to correct the interference at
his own expense.
Shielded cables must be used with this unit to ensure compliance
with Class A FCC limits. The connection of a nonshielded equipment interface cable to this equipment will invalidate the FCC Certification of this device and may cause interference levels which
exceed the limits established by the FCC for this equipment. It is
the responsibility of the user to obtain and use a shielded equipment interface cable with this device. Do not leave cables connected to unused interfaces. Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.

The QC100 is capable of great accuracy and precision and may
surpass the measurement-accuracy capability of the human operator. The system is also capable of displaying higher resolution
and more significant figures than is often needed. These facts
may be important in your interpretation and use of the measurement data provided by the system.

System configuration and
setup
Metronics, Incorporated assumes that all QC100 systems will be
configured and setup for the end-user by dealer or OEM representatives. This setup includes calibration according to the user’s
optical comparator or similar device, and configuration of error
compensation if necessary.
When the end-user installs a new comparator, it will probably be
necessary to perform configuration and setup again. In that case,
technically qualified supervisory personnel can refer to Chapter 4:
System Setup, or can contact their dealer representatives for assistance.

The Quadra-Chek 100® is an advanced digital readout system for
performing 2, 3 and 4 axis measurements at very high levels of
precision and accuracy. The QC100 can be used with optical comparators, toolmaker’s microscopes, touch-probes and video measurement systems to perform precision measurements as part of
in-line production activities or final quality inspection.
The intuitive interface will be familiar to users of the Quadra-Chek
1000® and other Metronics products. Operators will find the
QC100® easy to understand and use thanks to a large LCD display
and front panel keys clearly marked with familiar function and
mode symbols.
The large LCD displays alphanumeric and graphic information for
the current measurement, measurement features and measurement data clearly on one screen, eliminating the need to page or
scroll for information.
Panel keys are provided for entering numeric data, zeroing
axes, turning the LCD on or off
and sending data to a printer or
computer.
Softkeys are also provided that
work in conjunction with changing measurement-specific functions displayed on the LCD
screen.
Two large FastTrack keys located
over the LCD can be programmed as hotkeys that initiate frequently used system
functions and can be quickly

Measurements viewed on the front panel LCD can be transmitted

port connection, or to a printer over a parallel or serial port. An
infrared (IRDA) port is also included on the front panel for communication with computers and other infrared-compatible devices.
Quadra-Chek® QC100
The compact ergonomic design
and adjustable-tilt front panel of
the QC100 allow users to locate
and mount the instrument in a
wide variety of environments to
accommodate nearly any viewing requirement. The tilt front
panel can be adjusted and secured in any convenient position. Rubber feet on the bottom
prevent slipping when the system is not permanently bolted
to a worksurface. Bolt holes are
provided in the mounting stand
that match the pattern of the
QC 1000.
Available options and

An optional foot switch and remote keypad are available for
control and data entry when the
user is not close to the front
panel.

Operation
This chapter describes how to operate the QC100. Instructions
will show typical LCD screen contents. This chapter includes:
• Measuring with the QC100page 2-2
• Probing and targetingpage 2-2

The contents of LCD screens will reflect a system using X and Y

slightly different defaults and operating parameters, however the
instructions in this chapter are generic and will apply equally well
to all systems.

Chapter 2Operation
Measuring with the
QC100
Probing and targeting
Datum
The QC100 performs very precise dimensional measurements. Part
measurement is a simple process that includes positioning and
securing the part for measurement, establishing a datum and probing the part by targeting data points. The measurement result is
displayed on the DRO screen and can be printed or sent to a computer.
Once a datum has been established, points can be
measured by
ometry using crosshairs or by sensing the part with a touch-probe.
Crosshairs are targeted over a point by moving the part in the
stage. When a touch-probe is used, the probe is placed in contact with the part and indicates the part surface displacement as
the part is moved. In either case, displacement information is
displayed continuously on the DRO screen.

The locations of probed or targeted points are always referred to
an absolute datum point or origin. The absolute datum coordinates are 0,0. The absolute datum can be set to any physical
point on or off the part being measured by pressing Zero axes
keys on the front panel. Setting the absolute datum and orienting
the axes establishes a reference frame within which a second (incremental) datum can be defined for incremental measurements.

The datums can be zeroed using the Zero axes keys or can be set
