The operation of the LB 147 is very easy by means of the touch panel on the graphical display and the clearly arranged menu structure. The monitor can be switched easily between different lead nuclides before the measurement. Each detector has its own calibration factor for each nuclide and a spillover factor for each alpha nuclide. The input of all parameters is password protected. Calibration factors for more than 50 nuclides in accordance with DIN ISO 7503-1 and A-100 (DIN 44801) are already existing in the software.
The background radiation is continuously monitored for each detector and used to compensate the measurement with the long-term average background value. Before the start of each measurement the background is checked for fluctuations.
The detection limits are calculated according to DIN ISO 11929 for each measured value and will be stored together with the measurement values.
The LB 147 complies with the requirements of the international standard IEC 61098. This is true in particular for the detector performance, the manufacturers’ calibration procedures and the determination of efficiencies.
Numerous service functions permit easily measurements for necessary periodical tests. These include automatic plateau measurement, calibration routines for all detectors and a fast system test.
Up to 10000 measuring data can be stored and transferred via USB, Ethernet, RS 232 or RS 485 to an external computer. A simple communication protocol permits the integration into a measuring network.
As an option, a alarm column, transponder, card reader or printer can be connected. If requested, a gate can be released if no contamination is detected.
The hand-foot monitor is also available as LB 147 narrow-version with a changed positioning of the hand probes.
