3.3. Balance levelling 
 
To do the measurements correctly level the scale. Take the pan off carefully 
(without rapid pulls and hits) and turn the legs in order to level the balance, air 
bubble should be place in the centre of level condition indicator.

4. UNDER-FLOOR WEIGHING 
 
For scales with 165 x 165mm platforms can weigh underslinged loads (hanged 
under the balance floor). In case of using this function: 
 
− remove the hole plug made of plastic (placed in the balance floor), 
− a suspension can be seen in the hole. It is standard equipment, 
− Mount an appropriate hook for hanging loads (hook is non-standard 
equipment). 
 
1. The suspense cannot be rotated, revolved or tampered in any way, 
because of direct connection with the weighing mechanism of the 
balance.  
2. All the additional elements like pan, string etc. should be tarred (TARE).  
3. Balances with 300 x 300mm or 410 x 410mm platforms do not have the 
under-floor weighing mechanism.
