SAFETY PRECAUTIONS 

For safe operation of the weighing indicator, please follow these 
instructions:

 

● Calibration inspection and maintenance of the indicator are prohibited by non-pro-

fessional staff

 

● Please ensure that the indicator rests on a stable surface

 

● The indicator is a piece of static sensitive equipment; Please cut off power during 

electrical connections

 

● Touching the internal components by hand is prohibited

 

● DO NOT exceed the rated load limit of the unit

 

● DO NOT step on the unit

 

● DO NOT jump on the scale

 

● DO NOT use this product if any of the components are cracked

 

● DO NOT use for purposes other then weight taking

 

● To avoid damaging the battery do not keep charger plugged in once battery is fully 

charged

 

● Make sure the weight is not over the Max capacity as it could damage the load cell 

inside

 

● Material that has a static electric charge could influence the weighing. Discharge 

the static electricity of the samples, if possible. Another  
solution to the problem is to wipe both sides of the pan and the top of the case with 
an anti-static agent

Please take anti-static prevention measures

Any accumulated charge on the body of the human operator should be discharged first 
before opening the protective container with ESDS devices inside. The discharge can 
be accomplished by: 

 

● Putting a hand on a grounded surface or, ideally, by wearing a grounded Anti-static 

Wrist Strap and an Anti-static Mat

PREPARATION & SET UP

 

● Plug into a wall outlet to avoid interference with other wirings

 

● Turn on the balance while there is no load

 

● We suggest to warm-up the balance by powering on 5 minutes before use for  

accurate weighing

 

● Calibration may be required before weighing when the balance is initially installed 

or moved from a location
