WEIGHT SCALE CALIBRATION –

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

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).
