KERN Communication Protocol (KCP ):
It is a standardized interface command set for KERN balances and other instruments, which allows retrieving and controlling all relevant parameters and functions of the device. KERN devices featuring KCP are thus easily integrated with computers, industrial controllers and other digital systems GLP/ISO log: The balance displays serial number, user ID, weight, date and time, regardless of a printer connection
GLP/ISO log:
With weight, date and time. Only with KERN printers.
Piece counting:
Reference quantities selectable. Display can be switched from piece to weight
Recipe level A:
The weights of the recipe ingredients can be added together and the total weight of the recipe can be printed out
Recipe level B:
Internal memory for complete recipes with name and target value of the recipe ingredients. User guidance through display
Totalising level A:
The weights of similar items can be added together and the total can be printed out
Percentage determination:
Determining the deviation in % from the target value (100 % )
Weighing units:
Can be switched to e.g. nonmetric units. See balance model. Please refer to KERN‘s website for more details
