SWING WEIGHT CALIBRATION –
It is important to periodically check the accuracy of the Swing Weight me asurement of the GAMMA R TC from time to time and make calibration
adjustments when needed. The RTC includes a Calibration Bar and Calibration Weight for this purpose.
A. B. C.
The Swing Weight can be checked at: (A) - 100 kg/cm2 with the Calibration Bar alone, (B) - 200 kg/cm2 with the Calibration Weight locked on
the bar at the “200” mark, and (C) - 300 kg/cm2 with the Calibration Weight locked on the bar at the “300” mark. When placing the Calibration
Bar into the Racquet Clamp, the flat edge on the bar should be facing up and the end of the Calibration Bar should rest against the backside of
the Racquet Clamp. Measurement accuracy is +/- 2 kg/cm2.
If the swing weight displayed on the LCD screen does not match the value of the Calibration Bar
within +/- 2 kg/cm2, adjust the display to match the value stated on the Calibration Bar by turning the
adjustment screw labeled “Swing” located on the back side of the PCB using the micro screw driver
provided with the RTC as pictured in Step (D).

WEIGHT SCALE CALIBRATION –
It is important to periodically check the accuracy of the W eight Scale measurement of the GAMMA RTC from time to time and make calibration
adjustments when needed. The RTC includes a Calibration Bar and Calibration Weight for this purpose.
A. B.
The Weight Scale can be checked at: (A) - 185 grams using the Calibration Weight alone and (B) - 270 grams using the Calibration Bar alone.
Measurement accuracy is +/- 1 gram.
If the weight displayed on the LCD screen does not match the value of the Calibration Weight
or Calibration Bar within 1 gram, adjust the display to match the value of the Calibration Weight
or Calibration Bar by turning the adjustment screw labeled “Weight” located on the back side of
the PCB using the micro screw driver provided with the RTC as pictured in Step (C).

TROUBLESHOOTING (SWING WEIGHT) –
When performing the Swing Weight Test, it is very important that the end of the racquet or Calibration Bar be positioned against the backside of
the Racquet Clamp as illustrated in Figure 1 below.
It is equally important that the machine table be level. If the table is tilted up at the front (Figure 2) the Swing Weight measurement will be higher
than the standard. If it is tilted down (Figure 3) the Swing Weight measurement will be less than the standard.
