Page 7: Basic Information (General)
Information is available on KERN’s home page (www.kern-sohn.com) with regard to the monitoring of balance test substances and the test weights required for this. In KERN’s accredited DKD calibration laboratory test weights and balances may be calibrated (return to the national standard) fast and at moderate cost. -
Page 8: Basic Safety Precautions
3 Basic Safety Precautions 3.1 Pay attention to the instructions in the Operation Manual Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances. 3.2 Personnel training The appliance may only be operated and maintained by trained personnel. -
Page 9: Unpacking, Setup And Commissioning
5 Unpacking, Setup and Commissioning 5.1 Installation Site, Location of Use The balances are designed in a way that reliable weighing results are achieved in common conditions of use. You will work accurately and fast, if you select the right location for your balance. On the installation site observe the following: •... - Page 10 Mount the display unit in a way that facilitates operation and where it is easy to see. 1. Display unit assembled For disassembly remove the assembly sheet by loosening the marked screws. After that the display unit can be placed freely. 2.
- Page 11 3. Using with tripod (optional) In order to raise the display, the display unit can be assembled to an optionally available tripod (KERN PCD-A03). Assembly see installation instructions of the tripod. The balance must be installed in a way that the weighing plate is exactly in horizontal position.

Page 12: Mains Connection
5.3 Mains connection Power is supplied via the external mains adapter. The stated voltage value must be the same as the local voltage. Only use original KERN mains adapters. Using other makes requires consent by KERN. 5.4 Operation using a rechargeable battery (optional) Lift-off the battery cover on the lower side of the balance. -
Page 13: Connection Of Peripheral Devices
Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always disconnect the balance from the power supply. With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance. -
Page 14: Linearisation
5.7 Linearisation (only models PCD 250-3, PCD 2500-2) Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range. If linearity deviation is discovered during a monitoring of test resources, you can improve this by means of linearization. - Page 15 Press repeatedly until LinEAr is displayed Ensure that there are no objects on the weighing pan. Start linearisation with . The value of the first adjustment weight will be displayed. (example) Place adjustment weight and acknowledge by .
-
Page 16: Adjustment
Place fifth adjustment weight and acknowledge . The scales will change to zero display. Take away adjustment weight. After a short time CAL F is displayed. Finally the balance will switch off automatically. Now the linearization is concluded successfully. -
Page 17: Adjustment
5.9 Adjustment The adjustment should be made with the recommended adjustment weight (see chap. 1 "Technical data"). Adjustment is also possible with the weights of other nominal values (see table 1), but not the optimum for measuring technique. Procedure when adjusting: Observe stable environmental conditions. -

Page 22: Parts Counting
7.7 Parts counting During piece counting parts can either be counted into a container or out of a container. To count a greater number of parts the average weight per part has to be determined with a small quantity (reference quantity). The larger the reference quantity, the higher the counting exactness. -
Page 23: Net-Total Weighing
7.8 Net-total weighing It is useful if a mixture of several components is weighed into a tare vessel and finally the sum weight of all weighed components is necessary for control purposes (net-total, i.e. the weight of the tare vessel). Example: 1. -

Page 31: Dosing And Zero-Tracking
8.3.2 Dosing and Zero-tracking The Auto-Zero function is used to tare small variations in weight automatically. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation“. (Example: Slowly draining fluids from a container on the balance). -
Page 32: Selection Of Adjustment Weight
8.3.3 Selection of adjustment weight In the model series KERN PCD, the adjustment weight can be selected from pre-set nominal values (refer also to following table, factory setting with grey background). In order to achieve high- quality weighing results in the sense of the measuring technology, it is recommended to select the nominal value as high as possible. -
