Page 17: Power Supply
Check if the scale voltage is set correctly. The scale can be connected to the mains only when the voltage specified on the scale (sticker) and the local voltage are identical. Always use the original power supply by KERN. Using any other prod- ucts requires KERN consent. Important information: ... -
Page 18: Battery Charging
Before you connect or disconnect any extra devices (printer, computer) to/from the data interface, the scale should always be disconnected from the mains. Use solely accessories and peripherals supplied by KERN with the scale, being per- fectly compatible with it. - Page 19 The adjustment weight precision must correspond to the interval [d] of the scale, though preferably it should be a bit higher. For information concerning reference weights, see online at: http://www.kern-sohn.com • Ensure stable environmental conditions. The heating time is required for the stabilization (see chapter 1).

Page 22: Counting The Number Of Pieces
8.6 Counting the number of pieces Before it is possible to count pieces using the scale, you should determine the average weight of an individual piece (unit weight), the so-called reference value. To do it, place the specific number of pieces which the counting the number of pieces will be carried out for. -
Page 23: Test Weighing
8.7 Test weighing The function is available starting from weight values above 20 d. Activating the test weighing mode: In the weighing mode, press TOL, < > will be displayed. Pressing TOL enables to switch between < > and < >. - Page 24 Setting conditions of sending and limits: 1. In the weighing mode, press and hold the TOL, < > will be displayed. 2. Using the TARE button, select the required signaling condition. You can choose: If the weighed portion is in the present limit range, a sound is heard and a LED at the [ ] is green.
- Page 25 Tolerance check start: Ensure the test weighing mode is active. To do it, press TOL several times until < > is displayed. Place the weighed material (< 20 d) and, based on the tolerance symbols / audible signal, check if the weighed material belongs to the preset tolerance range.
