About Calibration
Calibration is the function to adjust the scale so that it
can weigh accurately.
When the verification seal is broken, re- verification is
required.
Break the verification seal and locate the CAL switch
cover on the scale bottom. Slide the CAL switch cover
in the direction indicated by the arrow.
The CAL switch is on the board inside.
When pressing the CAL switch, do not use a sharp
object such as a ballpoint pen. It may cause the scale
to malfunction.
