E-01 is displayed.
• E-01 is displayed when the impedance shows an abnormal value
compared to height and weight.
Please make sure that measurement was carried out with bare feet, the
electrodes or the soles of the feet were clean, and the feet were correctly in
contact with the electrodes. If the feet are dry or have calluses, place water on
the electrodes before stepping on the unit.

• Please refer to the readings of other parts for the body fat.
E-11 is displayed.
• E - 11 is displayed when there is a loose connection between the control
box and the weighing platform.
• Confirm that none of connections between the scale and control box are
loose or unplugged.
• There may be excessive vibration which will disturb the measurement process.
E-12, 13 or 14 is displayed.
• The equipment requires readjustment.
E-16 is displayed.
• Measurement is not possible because impedance is unstable. In order to
improve electrical conductivity, please clean the soles of the feet or
place water on the electrodes before using the equipment.
