3. Basic Information (General) 3.1. Proper use The balance you purchased is intended to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic“ balance, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing plate. As soon as a stable weighing value is reached the weighing value can be read. 3.2. Improper Use Do not use balance for dynamic weighings.
3.4. Monitoring of Test Resources In the framework of quality assurance the measuring-related properties of the balance and, if applicable, the testing weight, must be checked regularly. The responsible user must define a suitable interval as well as type and scope of this test. 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.
6. Unpacking, Setup and Commissioning 6.1. 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.
Your balance in overview: Air bubble Covering lid over underfloor weighing device Rear view: RS 232 interface Printer interface Connection net adapter 14 Antitheft device PES/PEJ-BA-e-1316
6.3. Scope of delivery Serial accessories: Balance Weighing plate Mains power supply Operating Manual Protective cover 6.4. Setup Positioning of weighing plate: Levelling balance: Use the foot screws to level the balance until the air bubble in the bubble level is in the prescribed circle.
6.5. Mains connection Power is supplied via the external mains power supply. The stated voltage value must be the same as the local voltage. Only use original KERN mains power supplies. Using other makes requires consent by KERN. In the menu you can activate the AUTO-SLEEP function . In net operation the balance after 3 min without load change or key pressure passes in a sleep mode. Automatic activation of the display by load change or by pressing any key. 6.6.
6.8. Initial Commissioning A warming up time of 10 minutes after switching on stabilizes the measuring values. The accuracy of the balance depends on the local acceleration of gravity. Please be sure to observe the information in the chapter on adjusting in chap. 6.9. 6.8.1. Power display Supply balance with power via the mains power supply. Balance is in stand-by mode (green LED is on). Use the ance on.
6.8.2. Bar graph display In configuration menu 1 (chapter 7) you can activate/deactivate the bar graph display. * weihging dish ist unloaded Wägeplatte unbelastet Hide bar graph Show bar graph half of weighing range Waage weighing range is used halbe Höchstlast ist mit Höchstlast belastet to full capacity The weighing range of the balance is divided into 40 graphic cuboids. Zero (0) will appear on the graphic display if there is no weighing value on the balance.
6.9. Adjustment As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the balance has not already been adjusted to the location in the factory). This adjustment process must be carried out at every commissioning, after each change of location as well as in case of fluctuating environment temperature.
