SYSTEM PARAMETERS
Axis-specific parameters; individual settings may be for each axis:
Axis Type: (linear or angular).
Factory Default: linear
Encoder Resolution: Use the numeric entry routine.
Factory Default: all axes: 2um (linear)
Encoder Direction: ("pos" or "neg") for linear encoders only.
Factory Default: "pos"
(for standard sense)
Display Resolutions: mm, inch, deg, dms
Pre-scale Factor
Used as multiplier for odd resolutions where a linear system is composed of a rotary
encoder and lead-screw. Since only specific operator required values are meaningful,
no value menu is provided. This parameter can only be entered via the numeric entry
routine or from a computer via the RS-232 port .
Factory Default: 1.000000
Linear Error Compensation Factor
Correct an encoder-generated measurement using this factor to produce a displayed
measurement. Since only specific operator required values are meaningful, no value
menu is given. This parameter is calculated by a "correction" routine using the
observed numeric entries vs actual measurements. Positive and negative values for
the LEC factor are allowed but the numeric values are all positive.
Factory Default: 0 ppm (no compensation).
Incremental Offset
This parameter can only be set by zeroing operations while using the unit. It cannot
be set via the RS-232 port from a computer except as key strokes. The offset can be
zeroed by specific zeroing operations or by resetting all parameters. Positive and
negative values are created.
Factory Default: zero

FEATURES
1-8
ACCESSORY/OPTION PARAMETERS
These parameters are set for proper option and accessory operation. Factory setting:
Each parameter has factory-set defaults. If the option or accessory is not installed do
not change the parameters. Changes may cause unexpected results.
Communications Operations (RS-232 port)
The RS-232 port is a serial port that allows two-way communication of data between
an external computer and the readout, or downloading data to a recording device, such
as a printer. Refer to the "RS-232 communications" section for details.
Note: the parameters controlling the RS-232 operations initially may have to be set
within the unit, to establish communications with an external computer before the
computer can pass data to the unit.
The following parameters are set internally and cannot be changed:
PARITY 0
STOPBITS 2
WORDLENGTH 8
PROTOCOL Hardware
The parameters below are presented as menus from which to make the selection:
Factory Defaults: BAUD RATE 600
END-OF-LINE CHARACTER Carriage Return
AXIS I.D. CHARACTERS X
PRINT On for all axes
Edge Detector
Set parameters when the detector is activated. Serves as a remote PRINT key and/or
display "update" when the detector is activated.
Factory Default: printing off, update off.

FEATURES
1-9
OPTIONS
The QC-1000 may be equipped with the following options. These options are
available at the time of equipment purchase or any time afterward. The installation of
some options for QC-1000 systems in the field may require the system to be returned to
Metronics for reconfigure of the software and hardware. For additional information,
please refer to the specific options paragraph.
RS-232 INTERCONNECTING CABLES
These cables are the standard product cables as used for the QC-3000 series.
FOOTSWITCH
The footswitch is the standard Metronics two key footswitch. The large key is used
to zero all axes. The small key is used as a PRINT key
EDGE DETECTOR
The edge detector option is activated when the edge detector senses an edge of a
part. When activated the edge detector can act as a remote PRINT key. When set to
act as a remote PRINT key the action is the same as pressing PRINT.
When set to "update" the displays, the displays remain fixed at the measurement
shown when the parameter was set. Further movement of the encoder will not change
the display. When an edge is detected, the displays "update" to the current
measurement "freezing" on those measurements (the measuring information has
continued to be updated internally, but is not shown). Again, further encoder movement
will not change the displays until the next edge is sensed, or the feature is turned off.
Note that when both printing and updating actions are set, the displays are updated
immediately prior printing.

SECTION II
OPERATING INSTRUCTIONS
POWER-UP
Plug in the power cord and turn on the power switch, located on the back beside the
plug receptacle. The Quick-Chek will show a non-flashing message"SF t 1.00" in the
left-most digits of each display. This message shows the software version installed in
each axis and indicates that the power has been off.
Press the DISPLAY ON key to clear the message, zero the displays and ready the
unit for normal operation. Indicators under each axis display will be lit to indicate the
factory settings for the measure mode (ABS) and measure units (INCH).
NORMAL OPERATION
The unit operates similar to most digital readout products (such as Quadra-Chek
units). It will indicate measurements of movement on a display for items like milling
machine tables, lathe beds or slides, coordinate measuring machine tables, etc.
All displays may be switched between incremental and absolute measuring modes by
using a single key. The current mode is indicated by an ABS or INC message in each
display.
Measurement units may be switched between English and metric units with a single
key. The current selection is shown with an INCH or MM message in each display.

OPERATING INSTRUCTIONS
2-2
If any axes are to be used for angular measurements, a single key will switch between
decimal degrees and degrees-minutes-seconds displays. Those axes will show a DEG
or DMS message in the display.
If an encoder counting error occurs while using the measuring system, the affected
axis will immediately show a flashing "ERR" message directly beneath the
measurement display for the affected axis. The measuring information continues to be
displayed but THE OPERATOR SHOULD NOTE THAT THE MEASUREMENT MAY
NOT BE ACCURATE. The operator should reset the counter in both measuring modes
at the first opportunity by using the REF features or pressing DISPLAY ON. Pressing
the DISPLAY ON key will also zero both ABS and INCR modes and clear the error.
The axis display for the current measurement mode either ABS or INCR may be
zeroed at any time by pressing the appropriate ZERO key for effected axis. Note that
both modes are not zeroed, only the current mode. The alternate mode can be zeroed
by changing modes, then pressing the appropriate ZERO key.
The absolute mode displays may be zeroed and the incremental mode reset to the
last offset in combination with an encoder reference signal. Pressing the REF key will
activate the reference signal function for all axes. When the encoder is moved past its
reference mark the absolute mode will be zeroed, the incremental mode reset, the REF
message extinguished and errors cleared. Pressing the REF key again will deactivate
the REF function and turn off all remaining REF messages.

OPERATING INSTRUCTIONS
2-3
When the unit is turned off by pressing the DISPLAY OFF key, the display will blank
but the readout will retain the current position information. If the encoders are moved
while the unit is "off", this movement will be recorded internally and the measurement
will be shown when the unit is turned "on". Any display messages that would have
shown if the unit were "on" will be displayed when the unit is turned "on". Note that
while the unit is "off' no front panel key presses will be acknowledged or stored. Press
the DISPLAY ON key to again turn the display on and continue normal operations.
If the power to the system is lost or the rear-panel ON/OFF switch is turned "Off" all
positioning information will be lost. When the power is restored a steady display of "SF
t X.XX" in all axes indicates that the power has been interrupted. Press DISPLAY ON
to zero all axes and return to normal operation. If reference offsets were used the
encoder reference mark should be scanned also.
USING THE QUICK-CHEK
1. Turn "ON" the Quick-Chek by pressing the "ON/OFF" switch located at the rear of
the the unit beside the power plug. All axes will read SF t X.XX.
2. Press the DISPLAY ON key to clear the software message. 0.00000 INCH/ABS will
show in the display window.
3. Establish Absolute Zero by moving the encoder to a known position and pressing
the axis ZERO key or by using the Reference feature.
4. Repeat step 3. for each axis being used.
5. Perform the operation that you wish.

OPERATING INSTRUCTIONS
2-4
FRONT PANEL KEYS, PRIMARY FUNCTION
Each front panel key is labeled to indicate its primary function which is explained in
the following paragraphs.
PRINT The primary function is to enable the system to transmit axis
information thru the RS-232 port to a printer. If a computer is
connected to the port, pressing the key will initiate a transfer of data
to the computer. The PRINT key has no primary function if a device
is not connected.
REF The primary function enables the encoder reference axis display
zeroing feature. A single key press will turn the axes "On". If any
axes are "On" a second key press will turn the axes "Off".
DEG/DMS The primary function provides the toggling of all axes between
decimal degrees and degrees-minutes-seconds display modes.
INCH/MM The primary function toggles the active measurement axes
between inches and millimeters for the linear measuring mode.
INCR/ABS The primary function provides toggling of all axes between
incremental and absolute measuring modes.
DISPLAY ON The DISPLAY ON key primary function reactivates the display and
clears errors.
If the displays indicates a loss-of-power after initial power-up, press
the DISPLAY ON key to zero all displays in both incremental and
absolute modes.
DISPLAY OFF The primary function of the DISPLAY OFF key is to turn "Off" the
display. Encoder counting information is still processed.
ZERO The primary function of each ZERO key is to zero its associated
display.
A single beep signals each key press. A triple beep signals loss of power to the
system.

SET-UP PARAMETERS
The system set-up parameters reflect the encoder resolution which is an integral part
of the measuring system. The factory settings are the defaults that are active when the
system is turned on. The factory settings may be changed to reflect installed
accessories, options and operator preferences for the system features.
Parameters which can be set for each axis include encoder resolutions, display
resolutions, linear or angular measurements, encoder direction, pre-scale factor and
linear error compensation. Default values and communications parameters can be set
for options and peripheral equipment such as a printer, edge finder or computer.
The Quick-Chek setup mode can be used to select new settings to change the system
parameters or may be used to reset the unit to the factory settings.
Refer to the Setup paragraph for the program steps and selections. The prompt
messages are shown in the appropriate display windows for the menu items or list of
parameter selections. Refer to the Appendix section for the seven-segment
alpha/numeric display characters used in the display windows.
The current default parameter is shown for each setting. If a list of setting selections is
given the list begins at the current setting. Pressing the PRINT key (which acts as a
"NEXT" key) displays the next item on the list. Refer to the Setup section for a list of key
secondary functions. Setting displays scroll to the top of the list and repeat until a
selection is made. The new settings are entered into the program by pressing the
ZERO key which acts as a SELECT or ENTER key.
Other parameters are set by using the numeric entry routine while in the setup mode.
Parameters that utilize the numeric entry routine include encoder resolution (linear or
angular), pre-scale factor, and error compensation factors.
The current system parameter selection that can be selected is shown in the lower
display only. All other axes show a row of minus signs indicating that the unit is in a
program mode.
Press the axis ZERO key to select the axis for a parameter for axis-specific
operations. When a specific axis is being set only that display will show the parameter,
the other displays will show a row of dashes. The lower display shows all system
parameters plus those of the lower axis.
