Troubleshooting 

Possible causes 

Solution 

Power-on 

problem 

No display after press 

the button 

Not well load with the batteries or no 
electricity or not well insert with adapter or

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 

there is something wrong with the 
crystal-oscillator on PCB, or MCU not well 
insert  

Replace the crystal-oscillator; well 
insert the MCU. 

Display 888888,not 
back to 0 

Something wrong with the keys, or faulty PCB 
board 

Check the key button; Replace the 
PCB 

Err 

Err04 

0 point exceed the 10% of the data when 
calibrating; There are objects on the platform; 
Load cell 0 point changes; 

Remove the objects on the platform; 
calibrate again. 

Err05 

0 point exceed the 10% of the data when 
calibrating; There is one foot not stand on the 
solid base; Load cell 0 point changes;
