Standard

External adjustment: Adjusting accuracy using external adjustment weight
Data interface RS-232: For connection to printers, PCs or other peripheral devices for data transfer over longer distances. Network in bus topology possible
Data Interface USB: For connection to printers, PCs or other peripheral devices
KERN Communication Protocol (KCP): 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
Piece counting: Reference quantities selectable. Display can be switched from piece to weight
Net total: The weight values of the recipe ingredients can be added up and the total weight of the recipe printed out
Percentage determination: determining the deviation in % from the target value (100 %)
Units can be switched to e.g. non-metric units
Measuring with tolerance range (checkweighing): Upper and lower limit values can be programmed, e.g. for sorting, portioning or for measuring coatings or material thicknesses. The process is supported by an acoustic and/or optical signal
Hold function: When the weighing conditions are unstable, a stable weight is calculated as an average value
Universal plug-in power supply: With universal input and optional input socket adapters for EU, CH, GB or EU, CH, GB, US or EU, CH, GB, US, AUS
Weighing principle Strain gauges: Electrical resistor on an elastic deforming body
Package shipment by courier service: The duration of internal product provision is one day

Option

Rechargeable battery pack: Rechargeable set
Accredited calibration (DKD): The duration of the accredited calibration is 3 working days

Factory

Data interface Bluetooth: For connection to printers, PCs or other peripheral devices

Description

  • Wide range of functions including statistics, recipe and totalling functions Weighing with tolerance range (checkweighing): a visual and audible signal helps with portioning, dispensing or grading
  • Standardised, convenient KERN concept of operation: All primary functions have their own key on the keypad
  • Automatic internal adjustment, time-controlled every 2 h, guarantees high degree of accuracy and makes the balance independent of its location
  • Capacity display: A bargraph display lights up to show how much of the weighing range is still available
  • USB data interface for transferring weighing data to the PC, printer etc.
  • Small draught shield as standard, removable, Weighing space W×D×H 134×128×80 mm
  • Protective working cover included with delivery

Applications

Main fields of application / Primary application areas

  • Jewellery and gold trade
  • quality control
  • Laboratory applications
  • Dental laboratories
  • Plastics technology
