Quick Calibration
This section describes the Quick Calibration function.
Quick Calibration
The SR-750 Series automatically adjusts parameters for reading the target codes
through the main unit button operation or AutoID Network Navigator and store the
settings in its internal memory.
This function is called "Quick Calibration".
Set the calibration condition by using AutoID Network Navigator or sending the
setting commands.
„ Setting items of calibration conditions
• Camera settings
Set the brightness adjustment mode, exposure on high speed mode, offset and
dynamic range.
• Tuning options
Set the tuning method, multi read and inverse read.
Quick Calibration Function Operation
The following are the quick calibration methods.
• Using the main unit buttons
• Using the input terminal
• Using AutoID Network Navigator
Each operation method is described.
Activation using the button on the panel
Use the button on the panel of the SR-750 Series to activate the quick calibration.
When the
button is held down for 2 seconds in Quick Calibration mode, the
quick calibration is canceled and the SR-750 Series returns to Run mode.
1
Set up the SR-750 Series and prepare the code that is going to be
read.
2
Press the button quickly to start the laser pointer emission and
adjust the reading position.
After the adjustment, press the button quickly to turn off the laser pointer.
* When SR-75L4 or SR-75L6 is attached, the emission of the laser pointer is
not visible.
3
Press and hold the button for two seconds to perform quick
calibration.
During the quick calibration, the multiple
LED indicator illuminates as shown on the
right.

After the calibration, the reading rate measurement is performed
automatically.
Once the calibration finishes successfully, the
SR-750 Series starts the reading rate
measurement.
Check the level of reading stability on the
multiple LED indicator.
If the reading failure continues for a certain period of time, the quick calibration
is performed again.
If the calibration fails, "F" or "H" is displayed
By pressing the
button, you can perform the quick calibration again.
• F: Displayed when the quick calibration
failed.
• H: Displayed when the quick calibration was
completed successfully but the reading
failed and another quick calibration was
attempted but failed.
By pressing the
button, you can register
the result of the successful calibration.
5
Press the button and select the parameter bank in which to
register the parameters.
Every time the button is pressed, the
parameter bank number changes by one.
When the initial settings have been changed
for the parameter bank being displayed, the
OK/NG/ERROR LED illuminates in red.
When the parameter bank number is 10, "0"
and "1" are displayed alternately.
6
When the parameter bank in which to register the parameters is
determined, press the
button to register the parameters.
When the parameters are registered
successfully, the multiple LED indicator
shows "d".
Activation using the input terminal
By assigning "Quick Calibration Operation" to an input terminal, you can use that
terminal to activate the quick calibration.
1
Turn on the input terminal to which the function has been assigned.
The quick calibration starts.
2
"1" is displayed.
Parameter bank 1 is overwritten with the
calibration result and the TUNING OK output
turns on.
When the calibration fails, the OK/NG/ERROR
LED illuminates in red, the ERROR signal is
output, and the calibration operation ends.
Point When the input terminal is used to activate the quick calibration,
the calibration result is automatically written to parameter bank
No. 1.

Turn off the input terminal.
