3 Fundamental information (general) 3.1 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. 3.2 Inappropriate use Do not use the balance for dynamic weighing.
3.4 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.
6 Unpacking, installation and commissioning 6.1 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.
6.2.2 Package volume Serial fittings: KERN ECB • Balance • Operating manual • Power adaptor 6.3 Mains supply/ Battery operation 6.3.1 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. Mains adapter output voltage: 9V DC (polarity: inner terminal is negative) 6.3.
Rechargeable Battery Installation: 1. Remove battery cover 2. Slide spacer to left or right, lever down on corner, then remove the spacer 3.
6.4 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. 6.
7 Operation 7.1 Weighing • The balance is switched on by pressing the "ON/OFF" key. • The balance performs auto-diagnostics (for 2 s) and then displays "0.00". • If the weighing object is heavier than the weighing range the display indicates "E" (=Overload). • The balance is switched off by pressing the "ON/OFF" key once. 7.2 12 Taring (TARE key) • Switch the balance with the “ON/OFF” key on and wait until display appears as "0.00". Position the tare load and press the “TARE” key.
8 Maintenance, upkeep, disposal 8.1 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. 8.
9 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. .
