This video shows the basic operation of the Bella Geiger counter. This device probably comes from Ukraine, but maybe from Russia. The operation is very simple despite the Cyrillic lettering. On the right side there are 2 slide switches. With the lower one you switch on the device. With the upper one you switch on the acoustic signaling. On the upper side there is only the reset button. It can be used to start a new measuring process at any time. After switching on, the device starts immediately with a measuring process. One measuring process takes about 45 seconds. During the measurement 4 dots are shown in the display. When the measuring process is completed, only one point is shown in the display. The display is in the unit micro Sievert.
