Changing the scale place of operation

 

 

While moving a scale in another place of operation, all safety 
measures listed in point 5 of this instruction should be taken. 

Cleaning and maintenance 

 

Unplug the power adapter IEX-A01 from mains. 

 

Check wether the indicator´s electrostatic grounding is correctly plugged and is 
not defected. 

 

  Clean the scale and the housing with a slightly moistened cloth. You can use 

typical domestic cleaning agents. 

   For clearing an overlay of the indicator do not use agents that can 

mechanically scratch the surface. It includes an internal conductive layer that is 
important for save operation. 

  Platform levelling feet and shock absorbers are made of rubber. Within the 

hazardous area they need to be cleaned with a slightly moistened cloth. Moisture 
protects against gathering electrostatic charges. 

    While clearing the platform do not damage the masking springs. They are for 

gathering electrostatic charges from the weight pan. They should be ~5mm above 
the shock absorbers. 

   Cleaning should be performed  when there are no explosive gases. 

 There is forbidden to us concentrated acids, bases,  solvents or alcohol for 

cleaning the device.  

  There is also forbidden to use compressed air and high pressure washing 

equipment.
