3.6. POWERING THE DEVICE 
Balance can be connected to the mains only with a power adapter that comes standard with 
the particular model. Nominal power supply of the power adapter (specified on the power 
adapter data plate) should be compatible to the power from the mains. 
Plug the balance to the mains – connect the power adapter to the socket, next connect its connector 
to port located at the back of the balance housing. 
Test of the display unit takes place right after connecting the balance to the power, all the elements 
and pictograms are backlit for a short time. Next, the name and the program number appears, the 
indication gets to ZERO (displayed reading unit depends on the balance). During the balance start, 
the test of an internal mass adjustment mechanism  occurs (single location and elevation of the 
internal mass adjustment). 
If the indication is different than zero, please press 
 button. 
CAUTION!If the balance is “verified”, automatic adjustment occurs right after switching the balance on.
