This scale is an extremely sensitive weighing device. Items such as clothing or towels placed or dropped on the scale may cause it to
activate. In order to prevent run down of the battery, do not store or leave anything on the scale.
CALIBRATION
This scale has been factory calibrated and does not require calibration prior to use.
For maintenance, the calibration procedure may be performed using a known weight in either kilograms or pounds.
Simply set the scale for the desired unit of measure using the LB/KG button
and start the calibration procedure. The
calibration is performed using kg or lb, according to the unit of measure used upon entering into the calibration path,
meaning the scale will default to either kg or lb, if that was the setting left on the scale for weighing.
Note
: Calibration weight must be 5kg, 10kg, 15kg and 20kg as stated below.
