Product information "Kern CDS 4K0.02 counting balance 4 kg / 0.02 g"
The Kern CDS is a counting balance with weighing platform and remote indicator. The indicator measures 225 x 115 x 60 mm, hangs on a 2.5 m cable and can be mounted on the wall. Seven models count parts with a total weight ranging from 4 kg to 60 kg. The counting resolution is between 160,000 and 300,000 points, depending on the model. The minimum unit weight ranges from 20 mg for the CDS 4K0.02 to 200 mg for the CDS 36K0.2L and CDS 60K0.2, in each case under laboratory conditions.
Three platform sizes
The CDS 4K0.02 has the smallest platform (228 x 228 mm weighing pan, 103 mm high) and weighs 4 kg with a readability of 0.02 g. The models CDS 15K0.05, CDS 16K0.1 and CDS 30K0.1 share a platform measuring 308 x 318 mm with a height of 75 mm and weigh around 8 kg including the display unit. The large models CDS 30K0.1L, CDS 36K0.2L and CDS 60K0.2 have a weighing pan measuring 500 x 400 mm (127 mm high) and weigh approximately 12 kg. All models except the CDS 60K0.2 are fitted with a spirit level. The CDS 4K0.02, CDS 30K0.1L, CDS 36K0.2L and CDS 60K0.2 have adjustable levelling screws.
Operation in four steps
Kern describes the graphics-based control panel as self-explanatory. The sequence shows four steps from left to right: tare the container, load the reference pieces, confirm the reference quantity, and load the count quantity. The number of items appears directly on the display. According to the data sheet, the reference quantity can be set to 5, 10, 20, 50 or a custom number. The automatic reference optimisation gradually improves the average value of the unit weight. The balance is operated by seven keys; the backlit LCD has digits 21 mm high.
Additional functions
The PRE-TARE function subtracts a known container weight in advance. In addition there are percentage determination, weighing with tolerance range with visual and audible signal and a hold function that forms an average value under unstable weighing conditions. The units are switchable, including g, lb, oz and ct (excluding kg on the CDS 4K0.02). The CDS 15K0.05, CDS 16K0.1 and CDS 30K0.1 offer an optional hook for below-balance weighing.
KERN Universal Port and data connection
The KERN Universal Port (KUP) accommodates interface adaptors for RS-232, USB device, Ethernet, WLAN and Bluetooth BLE; according to Kern, these can be fitted without any installation effort. With the KUP-13 extension box, up to three adaptors can be connected in parallel. Via the KERN Communication Protocol (KCP), external controllers or computers can query and remotely control the balance. For the CDS 30K0.1L and CDS 36K0.2L, the data sheet also specifies an optional analogue output (0 V to 10 V). The balance is compatible with the Kern EasyTouch software.
Power supply
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 internal YKR-01 Li-ion rechargeable battery is optional. It takes 8 h to charge and, according to the data sheet, operates for 24 h with the backlight on and 48 h without. When connected to the mains, the balance does not switch off; when running on rechargeable battery power, the switch-off time can be adjusted. The ambient temperature may be between -10 °C and 40 °C, and the relative humidity up to 80 %.
Typical applications
- Inventory and order picking: counting quantities by unit weight
- Series production and manufacturing: counting parts on the production line and reconciling batches
- Goods receipt: checking delivery quantities of heavy parts up to 60 kg
- Small parts: screws, springs and stamped parts with a unit weight from 20 mg using the CDS 4K0.02
- Digital processes: transferring count values to a computer or ERP system via a KUP adaptor
