Solution
Power-on
problem
No display after
press the button
Not well load with the batteries or no
electricity or not well inser t with adapter or
plug.
Check if the batteries have been load
with the wrong connection, if well
connection with batteries; Replace new
batteries; Check the power supply with
the adapter
there is something wrong with the electric
components of power on PCB,
crystal-oscillator or IC
Replace with new PCB
Key button not work
Replace with new key button
Display irregular
character after
press button
LCD or its driver IC are not soldered well, or
are damaged; or some keys are not free to
move down or up
Replace LCD or its driver or re-solder
them,
Check the key button; Replace the PCB
Display 888888,

Err
Err04
zero point signal is over or blew the limitation;
or there are objects on the platform; or Load
cell is not at zero balance; or there is one foot
not stand on the solid base
Remove the objects on the platform;
calibrate again, change the load cell, Lay
the foot in the same level.
Err05
Err20
Load cell has no output; or the signal is too
small or too big; scale is not stable, or input
in-correct number or loaded wrong load
Check load cell and its wires ;replace
load cell, or PCB, then re-calibrate
Err01
The weight exceed 9d of the max capacity; or
the load cell output signal is too big
Remove the object; Or change the load
cell
Err31
Err30
The load cell signal is too small or too big.
calibrate again; Or replace the load cell;
Replace PCB
Err11
EEPROM on the PCB broken
Replace with new PCB
