CHAPTER 9.
CALIBRATION
The DRX 5 Series scales are equipped with Automatic Internal Calibration. Calibration is automatically
performed every time the scale is turned ON or initialized. Calibration is also performed every time the internal
temperature of the scale changes by 1° C or at 2 hour time intervals (whichever comes first).
When first plugged into the electrical wall outlet, temperature calibration will be performed regularly as the
internal temperature of the scale increases to its operating level. Once the temperature stabilizes temperature calibration
will be performed less frequently. To maintain the internal calibration of the scale leave the unit plugged into the wall
outlet and turn the scale OFF by using the ON/OFF key.
The calibration algorithm is designed not to interrupt the scale while it is in use. Therefore if calibration is
required the scale will wait until the unit has been inactive for 60 seconds (pan free of any weight, keys have not been
pressed, scale is stable).
The scale can be also calibrated at any time with the calibration key. Ta calibrate the scale follow the steps below:
1. Make sure the pan is free of any weight and the scale is stable.
2. Press the calibration key ∇ .
3. The scale will display a command asking to confirm internal calibration.
