CALIBRATION
Recalibration may be required if the load cell of the scale is overloaded due to dropping
something heavy on the scale, dropping the scale or other kind of misuse. (You need to
have a 2kg weight to proceed with the user calibration).
Turn off the scale (if it is currently turned on) and remove any weight on the platform.
Press ON/OFF key and while the scale is performing its self test (display is Selftest….),
press TARE/AUTO-CAL key. The scale will enter user calibration mode and will ask for
a 2kg weight to be put on the platform. Put 2kg weight and the scale will calibrate itself.
Once calibration is successful, the scale will go to weighing mode. To exit user
calibration without completing, simply press CE key.

Note: If the weight placed is not 2kg, the calibration will not proceed and the scale will
keep on asking for 2kg weight. The calibration procedure has to be carried out in an
extremely calm and non vibrating environment as it will affect the accuracy of the scale.
