SWING WEIGHT CALIBRATION –

It is important to periodically check the accuracy of the Swing Weight 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.

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).
