2.1.
3 Basic instructions 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 add-on weighing procedures, if small amounts of goods to be weighed are removed or added.
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.
6.3 Placing Remove transport locking (only models ILJ-C) To detach transport locking device, unscrew locking screw. For transportation screw in locking screw carefully right up to the limit stop.
6.4 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. 6.4.1 Turning On the Power Supply balance with power via the mains adapter. The display unit lights up and shown the software version. The weighing scale carries out a self-test and automatically moves into weighing mode.
7 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 for the first commissioning, after each change of location as well as in case of fluctuating environment temperature.
7.1 Automatic adjustment using internal weight (ILJ-C only) With the internal adjustment weight, the weighing accuracy can be checked and readjusted at any time. The automatic adjustment function is always enabled. You can start adjustment at any time by pressing the CAL-key manually. If a load is present on the weighing plate, the message LIMIT EXCEEDED will appear on the display. If the weight on the weighing plate is below 4% of max, the weighing scale nevertheless will be adjusted.
7.2 Menu settings Menu item „P1 ADJUSTMENT“ P1.1 P1.4 [Adjustment] ILJ-C ILS-C INT.JUST. - Internal adjustment, ILJ-C only - P1.2 EXT.JUST. External adjustment * - P1.3 BE.JUST.

7.2.2 P1.2 EXT.JUST.- External adjustment (ILS only) Carry out adjustment with the help of the recommended adjustment weight (see chapter 1 “Technical Specifications”). Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization. Ensure that there are no objects on the weighing pan. Press PRINT-key, JUSTAGE will be shown. Wait until the weighed value for the required adjustment weight appears.
7.2.3 P1.3 BE.JUST. User adjustment (model ILS-C only) This function allows the user to select a test weight of an arbitrary weight value. Having said this, the test weight should not amount to less than 30% of the maximum range. This function is not accessible in calibrated weighing scales! Start the process in weighing mode as shown on the picture. Digits will appear on the display, with the digit on the left flashing.
7.2.4 P1.4 TEST JUST. – Adjustment report (models ILJ-C only) This function is applied to compare the internal adjustment weight with the saved value. The test is carried out automatically. The result will be shown on the display and issued via the interface if an optional printer is connected.
7.2.5 Printing adjustment reports An adjustment report will be generated automatically after an adjustment and sent to the RS232 connection COM 1. For setting of adjustment report see chap. 17.1.1 Sample adjustment record: -------------------Just.Prot.-----------------Art Just External User Kern Draft Date 21.11.2013 Time 9:54:39 ID Balance 132051 Diff.Adjust. -0.2 g Signature ……………………………………………..
7.3 Verification General introduction: According to EU directive 2009/23/EC balances must be officially 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 d) For manufacturing final packages In cases of doubt, please contact your local trade in standard.
Position of the “official seals“: 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. 1/3 of the max. load) and compare with displayed value. The reverification deadline has been exceeded.
