Calibration - Gamma Progression Els Owner's Manual

Most tension calibrators (such as a Gamma Tension Calibrator) function by clamping off the
string attached to one the end of the calibrator and applying tension to the string located on
the opposite end of the calibrator. The tension measured by the calibrator will then display
the tension being applied to the calibrator by the machine. If the calibrator and tensioner do
not match then you can adjust the tensioner as follows:
(1) Turn the machine off and restart the machine while holding down the Test button until
the count down is complete. 22 lbs should appear on the display. (2) Apply tension to the
calibrator. (3) If the tension reading on the calibrator does not match the tension displayed on
the machine, use the tension indexing buttons to match the display to the calibrator reading
and press the Enter/Clear button (4) Release the tension applied to the calibrator and 44 lbs
should appear on the display. (5) Repeat steps #2-#4 for 44, 66 & 88lbs. (6) After completing
the adjustment at 88lbs the display will show 00 lbs. (7) Restart the machine without holding
any buttons and the calibration adjustment will be complete.
Switching the Buzzer Off and On
The stringing machine is equipped with a buzzer that sounds when any key or button is
pressed or when there is a problem with some function of the machine. The buzzer can be
disabled if desired for normal keypad entries.
To disable the buzzer, turn the machine on and while the display is counting down from 9 to
0, press and hold the Enter/Clear button for at least 5 seconds. The buzzer will be disabled
and will remain disabled. It can be enabled again by following the same steps listed above.
Note: Even when disabled, the buzzer will sound if the tensioner has a problem and the
machine requires attention. This is meant to alert the user of a problem, and can not be
disabled.

Tension Calibration Procedure
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 may not
be pulling at the correct tension you
can check the pulling tension with
a calibrator and make adjustments
if needed.
