Internal adjusting:
Quick setting up of the balance‘s accuracy with internal adjusting weight
(motordriven)
Adjusting program CAL:
For quick setting up of the balance‘s accuracy. External adjusting weight
required
Easy Touch:
Suitable for the connection, data transmission and control through PC or
tablet.
Memory:
Balance memory capacity, e.g. for article data, weighing data, tare weights,
PLU etc.
Alibi memory:
Secure, electronic archiving of weighing results, complying with the
2014/31/EU standard
KERN Universal Port (KUP ) :
allows the connection of external KUP interface adapters, e.g. RS-232, RS-485,
SB, Bluetooth, WLAN, Analogue, Ethernet etc. for the exchange of data and
control commands, without installation effort
Piece counting:

KERN‘s website for more details
Verification possible:
The time required for verification is specified in the pictogram
Control outputs (optocoupler, digital I/O) :
To connect relays, signal lamps, valves, etc. Weighing with tolerance range:
(Checkweighing) Upper and lower limiting can be programmed individually, e.g.
for sorting and dosing. The process is supported by an audible or visual
signal, see the relevant model DAkkS calibration possible (DKD ) : The time
required for DAkkS calibration is shown in days in the pictogram
Analogue interface:
to connect a suitable peripheral device for analogue processing of the
measurements Factory calibration (ISO ): The time required for Factory
calibration Hold function: is shown in days in the pictogram (Animal weighing
program) When the weighing conditions are un stable, a stable weight is
calculated as an average value Interface for second balance: For direct
connection of a second balance
Package shipment:
The time required for internal shipping prepa rations is shown in days in the
pictogram Protection against dust and water splashes IPxx: The type of
protection is shown in the
pictogram. Pallet shipment:
