4 Basic Information (General) 4.1 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. 4.
4.4 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.
6.2 Packaging / return transport Keep all parts of the original packaging for a possibly required return. Only use original packaging for returning. Prior to dispatch disconnect all cables and remove loose/mobile parts. Reattach possibly supplied transport securing devices. Secure all parts such as the glass wind screen, the weighing platform, power unit etc. against shifting and damage.

7 Unpacking, Setup and Commissioning 7.1 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. Therefore, observe the following for the installation site: • Operate the device only indoors.
7.2.1 Scope of delivery / serial accessories 1. Balance 2. Weighing plate 3. Carrier weighing plate 4. Screening ring 5. Mains adapter 6. Operating instructions 7.
7.2.2 Placing Attach circular screen, carrier of weighing plate and weighing plate in order. Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.
7.3 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. 7.3.1 Turning On the Power Supply power to balance via mains adapter. The display lights up and the balance carries out a selftest. In the ABJ models an automatic adjustment takes place. The selftest is completed when „OFF“ appears on the display. 7.
8 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.
Case 1: The load on the weighing plate is near zero. The weight symbol flashes for approx. two minutes, followed by „PSC.RUN“. After that the internal adjustment is started automatically. In order to ensure proper PSC operation, prevent vibrations and air flow. As soon as the display in grams reappears after completing adjustment via PSC, the balance returns to weighing mode.
Case 2: Weighing plate loaded The gram display flashes for two minutes, followed by „PLS.CAL“. Unload weighing plate. The gram display flashes again for 2 minutes; after that the internal adjustment is started automatically. In order to ensure proper PSC operation, prevent vibrations and air flow. As soon as the display in grams reappears after completing adjustment via PSC, the balance returns to weighing mode.
8.2 Menu settings „I.CAL“ / „E.CAL“ To invoke the adjustment function in weighing mode, press CAL for 3 sec. Acknowledge using PRINT, the current setting is displayed. Select the desired adjustment using the navigation keys ( ) I.CAL: E.CAL: Adjustment with internal weight (see chpt. 8.1) Adjustment with external weight (see chpt. 8.2) Confirm with TARE Press ON/OFF repeatedly or 3 sec., the balance will return into weighing mode The saved adjustment (I.CAL or E.
8.2.1 Adjustment with internal weight (KERN ABJ) With the internal adjustment weight, the weighing accuracy can be checked and readjusted at any time. • Condition: Menu setting „I.CAL“. • When an optional printer is connected and the GLP function activated, while starting the adjustment log „WAIT“ will be displayed. After the printout the adjustment will be continued automatically. • Adjustment may be interrupted with ON/OFF, „ABORT“ is displayed.
8.2.2 Adjustment with external weight (KERN ABS) • Condition: Menu setting „E.CAL“. • The weight to be used depends on the capacity of the scale. Carry out adjustment as near as possible to the balance’s maximum weight (recommended adjustment weight see chpt. 1). Weights of different nominal values or tolerance classes may be used for adjustment but are not optimal for technical measuring.
8.3 Adjustment log This function enables automatic log issue after each adjustment. These logs may be issued by using an optional printer. Printout example (KERN YKB-01N): ----------------CAL –EXTERNAL ----------------KERN & Sohn GmbH TYPE ABJ 220-4NM SN WBIIAB000I ID 1234 Mode of adjustment Company Model Serial no. Balance identification no. (see chpt. 8.4) REF 200.0000g Used adjustment weight BFR 200.0001g Before adjustment AFT 200.
How to change settings Press TARE Press ON/OFF repeatedly or for 3 sec., the balance will return into weighing mode 8.4 Balance identification no. This setting is for the balance ID number that is output along with the adjustment report. Call up menu In weighing mode press the MENU button twice Select menu item Press the navigation buttons ( ) repeatedly until „TOOLS“ is displayed. Confirm with PRINT Press the navigation buttons ( ) repeatedly until „SYSTEM“ is displayed.
9 Verification General introduction: According to EU directive 90/384/EEC or 2009/23EG 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.

13 Settings for Stability and Response Exists the possibility to tune the stability of the display and the degree of reaction of the balance to the requirements of certain applications or the environmental conditions. Most measurements can be carried out using default settings, that is, standard mode. In standard weighing mode, stability and reaction have the same priority. For certain applications such as e.g. dosage do use the dosing mode (pouring mode).

14.3 Formula mode The formula function allows to add on various components of a mixture. For check purpose, the weight of all components (CMP001, (CMP002 etc.), as well as the total weight (TOTAL) can be printed out. The balance works with a separated memory for the weight of the weighing container and of the formula components. In formula mode the „Auto zero“ function is not active (see chpt. 12.2). 1. Connect printer (see chpt. 15 „Data output“) 2.

15.2 Target mode This mode e.g. is used for weighing constant liquid quantities or for assessment of missing quantities or excess quantities. The target value is the numeric value which corresponds to the nominal quantity of the used unit. Beside the target value a tolerance value is entered. This is a numerical value which is plus/minus over or under the acceptable target value. The indicators or advise, when the target value is reached.

16 Data output The appliance interface allows a bi-directional data exchange from the balance to external devices. This data exchange is asynchronous using ASCII - Code. The following conditions must be met to provide successful communication between the weighing balance and the printer. • Use a suitable cable to connect the weighing balance to the interface of the printer/PC. Faultless operation requires an adequate KERN interface cable (optional).
