6.8 Initial Commissioning In order to obtain exact results with the electronic balances, your balance must have reached the operating temperature (see warming up time chap. 1). During this warm- ing up time, the balance must be connected to the power supply (mains, accumulator or battery).
6.8.2 Bar graph display half of weighing range weighing dish unloaded weighing range is used 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. 20 graphic cuboids are displayed if the balance is loaded up to one half of its weighing range.
6.8.3 Stability display Stable Unstable If the display shows the stability display [ο] the balance is in a stable status. The [ο] indication disappears if the condition is unstable. FES/FEJ-BA-e-1132...
6.8.4 Balance zero display Environmental influences can lead to the exact figure of “000.0“ not being displayed in spite of an empty weighing dish. It is, however, possible to reset your balance to zero at any time and thus ensure that weighing really does commence at zero. Set- ting to zero when a weight is applied is only possible within a certain type-dependent range.

6.9.3 Adjustment with internal weight (only FEJ) With the internal adjustment weight, the weighing accuracy can be checked and re- adjusted at any time. Procedure when adjusting: Observe stable environmental conditions. A warming-up time (see chap. 1) for stabi- lisation is necessary. Ensure that there are no objects on the weighing plate. Position of the verifying switch to the right (verifying position).

6.11 Verification General introduction: According to EU directive 90/384/EEC balances must be verified if they are used as follows (legally controlled area): a) For commercial transactions if the price of goods is determined by weighing b) For the production of medicines in pharmacies as well as for analyses in the medical and pharmaceutical laboratory c) For official purposes.

After verification the balance is sealed at the indicated positions. Verification of the balance is invalid without the "seal". Position of the “official seals“: Seals Seal Seal Balances with obligation to verify must be taken out of operation if: The weighing result of the balance is outside the error limit. Therefore, in regular intervals load balance with known test weight (ca.

10 Weighing mode The manufacturer’s standard configuration is "Weighing": Function [q SET.1], see chapter 7.2. Under this menu item, you can combine the function "Weighing" with the function “Parts counting” or “Percent determination” (settings see chapter 7.2). This way, 3 different weighing modes are available for you: 1.
10.1.1 Taring The dead weight of any weighing container may be tared away by pressing a button, so that the following weighings show the net weight of the goods to be weighed. Operation Display Place empty tare container on the weigh- ing plate.
Page 43
The taring process can be repeated any number of times, e.g. when adding several components for a mixture (adding). Reset display to "0": The total weight of the container is tared away. Add more components into the weighing container (adding). 457z9 Now read off the weight of the added item to be weighed on the display.

Entering limits is possible for the following functions: • Weighing • Parts counting • Percent determination There are several functions available for tolerance control of the balance KERN FEJ. There are two different ways to carry out evaluation of limits: 1. Evaluation of absolute values [24. TXP.1]: An exact reference value (e.g.
There are two different ways to set the tolerance limits: 1. Place the values (object) on the balance - > Save this value 2. Numeric entering of values - > Enter the limits via keyboard. NOTE: If a limiting value was set it remains saved until the balance is turned off. For the functions weighing, counting, percent individual limits can be set.
12.2.2 For 3 or 4 limits If 3 or 4 limiting points are to be set, this is displayed in the bar graph. The length of the represented bars indicates where within the tolerance range the weighed of the goods to be weighed are. A bar graph shows the different limits.
