Gamma 6500 Els Owner's Manual - Tensioner Calibration
Each stringing machine has been checked and calibrated at the factory using accurate load
sensing devices to ensure that the machine pulls at the correct tension. However, if you
suspect that your machine is not pulling at the correct tension, or if you would like to check
the pulling tension using a tension calibration device, you may do so.
To adjust the calibration of the 6500 Els machine :
1 - Set the tension so the display reads 30.0 lbs and turn off the machine.
2 - Turn on the machine while pressing the “C” button, and continue holding the
“C” button until the winder stops turning.
3 - Press the “L” button (the LED will be flashing with 30.0 displayed).
4 - Apply tension to a tension calibrator.
5 - Adjust the display to match the maximum reading observed on the
calibrator using the button with the yellow “UP Triangle” (Lbs/Kgs
button) or the button with the yellow “DOWN Triangle (String Length
Meter button).
Note : There will be a range of tension from the maximum tension at which
the tensioner stops pulling, to the minimum tension at which the tensioner
starts pulling again, for a given tension setting. The difference between the
maximum and minimum can vary between 2-4 lbs depending on the string and
calibration device used to calibrate the machine. Therefore, we recommend
that the tension setting of the machine be calibrated based on the maximum
reading to ensure consistency in the calibration procedure, which is also the
method used at the factory.
6 - Press the “L” button (display will stop flashing)
7 - With the calibrator still attached, increase the tension by turning the knob
until the calibrator shows approximately 70 lbs. (Note: display will stay on 30.0)
8 - Press the “H” button (the LED will be flashing with 70.0 displayed)
9 - Adjust the display to match the reading on the calibrator using the
button with the yellow “UP Triangle” (Lbs/Kgs button) or the button with
the yellow “DOWN Triangle (String Length Meter button).
10 - Press the “H” button (display should stop flashing)
If you have any problems with calibration of the machine, call the machine service
department of GAMMA Sports at 1-800-333-0337 for assistance.
