7 Troubleshooting
7.1 Scale does not turn on
n
Check the battery power which must be above 6V. In case the voltage is below
5.7V, charge the scale. If the voltage is less than 4.8V, you have to change the
battery.
o
Check the ON/OFF switch - if it is o.k. or any bad soldering.
7.2 Cannot use full capacity
n
Check the internal value according chapter 6
o
Put the maximum weight on the weighing pan. Press on the weighing plate to
check if the internal value can be shifting. It makes sure that the load cell is o.k.
If there is no changing, the load cell is damaged and you have to change it.
p
Check the overload screws. If all are o.k. you have to check/re-enter the
specification setting.
7.3 Display “OL” and buzzer “beep” after turn on
n
Check the wire of the load cell and the connection between load cell and main
board.

Check the load cell. If necessary, replace it.
7.4 Missing/unclear segment of the LCD display

Check the pins of CPU, if there are any short circuit, broken or cold soldering or
oxidized. If this, clean the pins by cleaning supplies and re-solder the pins.
o
Check the LCD display, the conductor rubbers and frames if there is a problem of
fixing.
p
Check the LCD display and the rubber itself. If necessary, replace it.
