This key is a composite key, while totalization is shown and weight returns to net zero, 
press M+ key to erase memory. RS232 will output MC print format (           output). 

 If there is new weight added on platter

it is less than 20 divisions in Brazil version, no 

accumulation 

, a new item will be added to totalization. If this weight is not taken off, 

nothing can be added to totalization.Display will show the totalization numbers for one 
second, then show net weight for one second, then the scale returns to the current 
weight, and prints out the last item for totalization. 

 To clear totalization data, press M+ key to let display shows up totalization numbers, 

then press the 

 M+|PRINT 

 key again, to clear totalization data. RS232 will print out 

totalization numbers, total weight, etc.  

    P.s.  Weight must return to net zero if to perform clear function.

 TARE|PT 

 key as 

“ZERO” or “PRINT” key 

 

If “PRINT” key is set (  

        = 10/11), all totalization data will be printed out, and   

totalization will be cleared. 

 If it is Brazil version and foot switch is set as Print function, it has  totalization function 

and print function. 

 

Simple Counting Mode 

Use 

 UNIT 

 key to switch unit to Pcs, to go into simple counting mode. 

1. Use 

 NET|GROSS 

 key  to select a 

sample number from “10, 20, 50, 100, or 200”. Display 

will show 

   

   

   

     

        

in an sequential order by pressing  

 

NET|GROSS 

 key. 

2. Select a sampling number, and put appropriate weight on platter, and press 

 UNIT 

 key. 

Display 

will show “           ”. The scale will go into counting mode after weight is 

stable, and display will show the sample number.  

 Unit weight insufficient (      ): Sample unit weight is 

less

 than 0.2d or total sample 

weight is 

less 

than 20d (d=division) 

 

While sampling, if there is insufficient sample or unit weight insufficient indication “

”, 

the scale is still usable, but there may be slight inaccuracy. 

 After Power-off, the scale automatically memorizes the sampling number, and it is 

available when 

“Pcs” unit is selected next time. 

 

If the setting is “automatic average unit weight “, if the object on platter > the previous 

sampling number more than 5 pcs, and also < less than 100% the previous sampling 
number, the scale will execute unit weight calibration automatically.
