Load the weighing pan with an animal. 

6.

 

On exceeding the set mass value of 

<Lo threshold>

 parameter, animal weighing starts, this is 

signaled with display of ‘dash’ 

<-     >

.   

7.

 

Upon process completion, mass value of an animal is snapped and displayed together with 

OK

 pictogram in the upper part of the display. The snapped mass value is sent to a scale-

connected printer.   

8.

 

Press 

 key to restart animal weighing. 

9.

 

Press 

 key to reprint the snapped mass value. 

10.

 

Upon unloading of the weighing platform, the weighing result window with letter 

A

 is 

displayed. The scale can be loaded with an animal again.

Maintenance 

In order to ensure safety in the course of cleaning, it is necessary to disconnect the device from the 
mains. With this condition met, uninstall the weighing pan and other detachable scale components. 
 

Note:

 Cleaning the weighing  pan while still installed may cause damage of the measuring system.  

 

19.1

 

Cleaning ABS components 

To clean dry surfaces and avoid smudging, use clean non-coloring cloths made of cellulose or cotton. 
You can use a solution of water and detergent (soap, dishwashing detergent, glass cleaner). Gently 
rub the cleaned surface and let it dry. Repeat cleaning process if needed. 
 
In the case of hard to remove contamination, e.g. residues of adhesive, rubber, resin, polyurethane 
foam etc., you can use a special cleaning agent based on a mixture of aliphatic hydrocarbons that do 
not dissolve plastics. Before using the cleanser for all surfaces, we recommend carrying out tests. Do 
not use cleansers containing abrasive substances. 
 

19.2

 

Cleaning stainless steel components 

Avoid using cleansers containing any corrosive chemicals, e.g. bleach (including chlorine). Do not use 
cleansers containing abrasive substances. Always remove the dirt using microfiber cloth to avoid 
damage of protective coating. 
 
In case of a daily maintenance: 

 

Remove the dirt using cloth dipped in warm water. 

 

For best results, add a little bit of dishwashing detergent. 

 

19.3

 

Cleaning aluminum components 

While cleaning aluminum components use products acid by nature, e.g. spirit vinegar, lemon. Do not 
use cleansers containing abrasive substances. Avoid using hard brush, this may cause scratches. It is 
recommended to use microfiber cloth. 
 
While polishing the surface use circular movements. Use clean, dry cloth to make the surface shine.
