Product information "Kern FCB 15K-3DM bench balance 6 / 15 kg, 2 / 5 g"
The Kern FCB is a range of bench balances from the Kern IoT-Line designed for checkweighing and portioning. Nine models cover weighing ranges from 6 kg to 30 kg. The readability ranges from 0.05 g on the FCB 6K-5 to 10 g at the upper end of the FCB 30K-3DM. All models feature a stainless steel weighing plate measuring 252 x 225 mm, a backlit LCD display with 25 mm high digits and a stabilisation time of 2 s. Interface adaptors can be connected via the KERN Universal Port (KUP), with up to three connected simultaneously via the extension box.
Three model groups
The single-range balances FCB 12K1 and FCB 30K1 have 12,000 and 30,000 divisions respectively, whilst the FCB 8K0.1 has 80,000. The FCB 12K-4, FCB 30K-4 and FCB 6K-5 models offer a finer resolution, with 120,000, 150,000 and 120,000 divisions respectively. The FCB 12K-4 has a readability of 0.1 g, the FCB 30K-4 of 0.2 g and the FCB 6K-5 of 0.05 g.
The third group comprises the multi-range balances FCB 6K-3DM, FCB 15K-3DM and FCB 30K-3DM. According to Kern, they automatically switch to the next weighing range and the corresponding readability as the load increases or decreases. For example, the FCB 15K-3DM weighs up to 6 kg with a readability of 2 g and up to 15 kg with a readability of 5 g. Only these three models are intended for conformity assessment under the NAWI Directive (2014/31/EU) and feature an alibi memory with 250,000 memory locations.
Connection via the KERN Universal Port
According to Kern, the KUP accommodates adaptors for RS-232, USB device, Ethernet, WLAN and Bluetooth BLE. The interfaces are optional and are operated as adaptors on the KUP connection. With the KUP-13 extension box, three interfaces can be used in parallel. Via the KERN Communication Protocol (KCP), computers or CRM and ERP systems can query the balance and control it remotely. The balances are compatible with the Kern EasyTouch software.
Functions for weighing and counting
For weighing with a tolerance range, two upper and two lower limit values are entered using four arrow keys; a visual and audible signal supports portioning, dosing or sorting. The balance counts items using reference quantities of 5, 10, 20 and 50, or a freely selected quantity, and determines percentage values. Weight values can be totalled, and manual taring can be performed multiple times. The units are switchable, including kg, g, lb and oz. On the single-range models, the Hold function calculates an average value in the event of unstable weighing conditions. The user guidance is available in English or as symbols; the balance is operated with six keys.
Power supply and design
The plug-in mains adaptor (100 V to 240 V AC, 50/60 Hz) is supplied with adaptors for EU, UK, US and CH. The Li-ion rechargeable battery YKR-01 with a charging time of 8 h is available as an option. According to the data sheet, it runs for 24 h with and 48 h without backlight; the auto-off time in rechargeable battery operation can be set to 30 s, 1 min, 2 min, 30 min or 60 min. The plastic housing measures 322 x 267 x 91 mm; when fully assembled, the dimensions are 325 x 270 x 105 mm. The aluminium load cell is silicone-coated and protected to IP65; the complete unit has no IP protection. The spirit level and adjustable feet are used for levelling. The working protective cover is included in the scope of delivery. The ambient temperature may be 0 °C to 40 °C for the single-range models and -10 °C to 40 °C for the DM models.
Typical applications
- Production and packaging: portioning, dosing and sorting with limit values
- Warehouse logistics: checkweighing of delivery quantities and counting of small parts
- Workshops: weighing of materials and components up to 30 kg
- Pharmacies: weighing larger quantities, down to 0.05 g with the FCB 6K-5
- Digital processes: transferring weighing data to a computer or ERP system via a KUP adaptor and KCP

Conformity assessment and calibration
For the FCB 6K-3DM, FCB 15K-3DM and FCB 30K-3DM, a conformity assessment under the NAWI Directive (2014/31/EU) is available as an option (item no. 965-228). It can only be ordered ex works together with the balance; according to Kern, a subsequent conformity assessment is not possible. To place an order, Kern needs the full address of the installation site. A DAkkS calibration certificate (item no. 963-128) can be ordered separately for all models. The confirmation of manufacturer specification (969-517) is only available in conjunction with the DAkkS calibration certificate.
