BBA422 / BBA425 / BBK422 Introduction 1 Introduction 1.1 Safety instructions CAUTION! Do not use BBA422 / BBA425 / BBK422 in hazardous areas! Our product range includes special devices for hazardous areas. CAUTION! Use only scales with Protection Class IP65, if: • the scale is used in wet areas • wet cleaning is necessary • the scale is used in a dusty environment Even with Protection Class IP65, the scale must not be used in environments with corrosion risk.
BBA422 / BBA425 / BBK422 Introduction CAUTION! Handle the compact scale with care. The scale is a precision instrument. ▲ When the weighing pan has been removed, never clean the area under the load plate holder with a solid object! ▲ Do not put excessive loads on the scale. ▲ Avoid banging the weighing pan. Disposal ➜ Observe the valid environmental regulations when disposing of the scale.

BBA422 / BBA425 / BBK422 1.3 1.3.1 Introduction Putting into operation Selecting or changing the location The correct location is crucial to the accuracy of the weighing results! ➜ Select a stable, vibration-free and if possible a horizontal location. The ground must be able to safely bear the weight of the fully loaded scale.
BBA422 / BBA425 / BBK422 Introduction 1.3.2 Connecting the power supply CAUTION! Before connecting the scale to the mains, check whether the voltage value printed on the rating plate corresponds with the local mains voltage. ▲ Never connect the device if the voltage value printed on the rating plate is different to the local mains voltage. ➜ Plug the mains plug into the socket. After connection, the device performs a self-test. When the zero display appears, the device is ready to weigh.
BBA422 / BBA425 / BBK422 2 Operation Operation 2.1 Switching on Switching on and off ➜ Press . The scale conducts a display test. When the weight display appears, the scale is ready to weigh. Switching off ➜ Press . Before the display goes out, -OFF- appears briefly. 2.2 Zeroing / Zero point correction Zeroing corrects the influence of slight changes on the load plate. Manual 1. Unload scale. 2. Press . The zero display appears.
BBA422 / BBA425 / BBK422 Operation 2.4 2.4.1 Weighing with tare Taring ➜ Place the empty container on the scale and press T . The zero display and the symbol NET appear. The tare weight remains saved until it is cleared. 2.4.2 Clearing the tare ➜ Unload scale and press T . The symbol NET goes out, the zero display appears. or ➜ Press C . The symbol NET goes out, the gross weight appears in the display. If A.
BBA422 / BBA425 / BBK422 2.5 Operation Dynamic weighing With the dynamic weighing function, it is possible to weigh restless weighing samples such as live animals. If this function is activated, the symbol appears in the display. With dynamic weighing, the scale calculates the mean value from 56 weighing operations within 4 seconds. With manual start Prerequisite AVErAGE -> MAnuAL is selected in the menu. The weighing sample must be heavier than 5 scale divisions. 1.
BBA422 / BBA425 / BBK422 Operation 2.7 Cleaning CAUTION! Electric shock hazard! ▲ Before cleaning with a damp cloth, pull out the mains plug to disconnect the unit from the power supply. CAUTION! When the weighing pan has been removed, never clean the area under the load plate holder with a solid object! This could damage the weighing cell. Other cleaning information: • Use damp cloths. • Do not use any acids, alkalis or strong solvents.
