CAUTION! 
The suspension for hook must not be turned, twisted or manipulated in any direction. Such 
actions may cause damage to balance mechanism.  
Mass of all additional elements of under pan weighing kit, like the hook, weighing pan, string, etc. should be 
zeroed by pressing 
 or  . 
 
11.3. COUNTING PARTS OF THE SAME MASS 
The standard version of a balance is equipped with an option of counting small objects of the same 
mass. 
When the function is initiated for the first time, mass standard weight equals 0.0000g. If the mass 
standard weight is determined and has been used in <PARTS COUNTING> mode, then the software 
accepts the most recently used mass value as the mass standard weight. 
 
11.3.1.  PARTS COUNTING Mode Settings 
The software allows entering settings of each working mode. Some settings are identical for all 
working modes. They are described in section relating to <WEIGHING> mode.  
This section covers only settings for <PARTS COUNTING> mode. 
 
F Shortcut Keys 
You can declare which particular weighing function is to be launched using F1, F2, F3 or F4 keys.  
For procedure informing you how to declare the particular function, read F Shortcut Keys section. 
 
11.3.2.  Setting the Reference Mass: Mass Determination from the Sample of Known Quantity 
While determining the mass of a single piece, ACAI function (Automatic Accuracy Correction) is in 
use.  
Means of operation of ACAI function: 
•  Number of pieces (on adding) on balance’s weighing pan has to be greater than before  
•  Number of pieces (on adding) on balance’s weighing pan must be less than twice the amount 
displayed before adding parts 
•  Current quantity of parts must be within the ± 0,3 tolerance of the total value,  
•  Measurement result has to be stabilised.  
 
  Procedure: 
•  Place the container on the pan and tare its mass, 
•  Press F button to which the function <DETERMINE SAMPLE> is assigned, wait to see the 
editing window <SAMPLE QUANTITY>
