-2APPLICATION The 6150AD is a portable, battery operated dose rate meter to measure photon radiation (gamma and X-radiation). A built-in GM counting tube serves as the detector. As implied by the letters »AD« in its name, the 6150AD displays the current dose rate in both analog and digital form. Furthermore, it permanently measures dose rate mean value, dose rate maximum value, and accumulated dose. All models have alarm thresholds for dose rate, some models also for dose. Some models have programmable thresholds that allow you to set alarm thresholds to any value within the instrument’s range....

-3FUNCTIONS Dose Rate Indication and Dose Rate Warning Dose rate indication is provided in digital and analog form simultaneously. The analog scale covers two decades and consists of 32 bar graph segments arranged in the shape of an arc. Two adjacent ranges always overlap by one decade. The 6150AD automatically switches ranges, where a short sound calls the user’s attention every time the range was changed. The loudspeaker key switches audible single pulse detection alternately on and off. The loudspeaker symbol in the upper right corner indicates that it is currently on. In case of dose rate...

SUPPLEMENTARY DEVICES (see separate data sheets) The Gamma Alarm Station 859.x accommodates one 6150AD and makes alarms particularly well noticeable, for example through flashlights. computer command. This allows monitoring several locations with one 6150AD and several probes according to a time-slice method. The Probe Multiplexer 861.x connects up to ten probes to a single 6150AD and scans the probes either automatically, manually, or according to an external The TELDOS system radio-transmits the 6150AD’s dose rate indication to a PC over distances of up to 500 m.
