USE IN LEGAL FOR TRADE APPLICATIONS : 

 

4.1 Introduction 

e

Nod3-

is a module making a part of an instrument. It is intended to be integrated : 

-

 

In a non automatic weighing instrument (

NAWI

) or 

-

 

In an automatic weighing instrument (

AWI

) of category catchweigher.

  § 3.2.33 Current measurement status 

 

4.3 Sealing 

The module 

e

Nod3-

C

 has a physical sealing device and a software sealing device. 

4.3.1 

Physical sealing : 

The physical sealing is the one of  the module box. It comprises two self-adhesive stickers self-
destructive when removed or a device with sealing screws with lead and sealing wire. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

4.3.2 

Software sealing : 

On the whole weighing instrument the value of the event counter as well as the CRC value may be 
displayed. 
The whole weighing instrument has a marking area where the values of the event counter and of 
the CRC recorded after the last official verification.These marked values shall be identical to these 
displayed on the terminal. When these values do not match, this part of the sealing device is 
considered as broken. 

4.4  Specific requirements : 

The legal metrological software version may be displayed on the terminal. 
There are also some characteristics in the status related to measurements that need to be 
displayed on the terminal too. 

 

Sealing with self-adhesive stickers self-

destructive when removed put on 2 

opposite sides of the box, with a part on 

the top and a part on the side of the box. 

Sealing with lead and sealing wire, 2 

opposite screws have to be sealed.
