4 Fundamental information (general) 4.1 Intended use The balance you have acquired serves to determine the weighing value of the 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. The weighing value can be read off after a stable weighing value has been obtained. 4.2 Inappropriate use Do not use the balance for dynamic weighing.
4.4 Monitoring the test substances The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals within the scope of quality assurance. For this purpose, the answerable user must define a suitable interval as well as the nature and scope of this check. Information is available on KERN’s home page (www.kernsohn.com) with regard to the monitoring of balance test substances and the test weights required for this.
7 Unpacking, installation and commissioning 7.1 Place of installation, place of use The balance is constructed in such a way that reliable weighing results can be achieved under normal application conditions. By selecting the correct location for your balance, you will be able to work quickly and precisely.
7.2 Installation Install the balance in such a fashion that the weighing plate is absolutely horizontal. 7.2.1 Unpacking the Balance Carefully remove the balance from the packaging and out of the plastic covering, then place the balance on the assigned position. 7.2.
7.2.3 Mounting instructions for using wall bracket 7.3 Mains supply Electric power supply is by means of the external mains supply circuit. The printed voltage level must comply with the local voltage. Only use original KERN mains supply circuits. The use of other makes is subject to approval by Kern. 7.4 Battery Operation Remove the battery cover underneath the display. Connect 6 x 1,5V round cells. Reinsert the battery cover.
7.5 Initial start-up A warm-up time of 5 minutes stabilises the measured values after switching on. The accuracy of the balance depends on the local acceleration of the fall. Please be sure to observe the information in the chapter on adjusting. 7.
8 Operation 8.1 Weighing Switch the balance on by pressing the ON/ key. The balance will show “88888“ for approx. 3 seconds and then change to “0“. Now it is ready for use. Important: If the display does not show “0“ press the TARE key. Only now (!) place object on the weighing pan. Make sure that the weighing object does not stripe or touch the housing or base. Now the weight will be indicated.
8.3 Hold function (Animal weighing function) The balance has an integrated animal weighing function (mean value) with which it is possible to weigh small or domestic animals (minimum weight 1% of max.) precisely, even when they do not stand still on the weighing platform. Remark: With to lively movement (strong diplay fluctuation) no mean value can take place. Place the animal to be weighed on the weighing platform and press the HOLD key.
9 Maintenance, upkeep, disposal 9.1 Cleaning Please disconnect the device from the operating voltage before cleaning. Only use a cloth dampened with mild suds and not aggressive cleaning agents (solvents or similar). Please ensure that fluids are not able to get into the device and rub off using a clean, soft cloth. Loose sample residue/powder can be removed carefully using a brush or hand vacuum cleaner. Remove any spilt material to be weighed immediately. 9.
10 Troubleshooting The balance should be switched off for a short time following an interruption in the programme sequence and disconnected from the mains supply. It is then necessary to repeat the weighing process from the beginning. Help: Interruption Possible cause Weight display is not illuminated. • The balance is not switched on. • The mains supply connection has been interrupted (mains cable not plugged in/faulty). • Power supply interrupted. .
