support 

Multi  zero  support  only  applies  to  supported  indicators  and 
protocols.  If  the  division  size  is  1x  or  higher,  when  the  weight 
display  returns  to  Zero,  the  D841/D850  will  also  display  the 
trailing zero. 
Example:  With  the  count  set  to  20,  an  indicator  displays  00  at 
zero load. The D841/D850 will also show 00 at zero as there is no 
leading zero blanking.  
NTEP is the National Type Evaluation Program in the US.
