Background Measurement
• Automatic background substraction
• Background updated every second
for each detector
• Measurement algorithm using two median filters
to follow any background change in real time
• Quickly fluctuating background does not lead
to measurement abort
• After background change automatic return
to status «ready»
Measurement
• Automatic calculation of shortest possible
measurement time
• P² accelerator to shorten measurement time for
non-contaminated personnel by up to 30 %
• Using preset fixed measurement time possible
• Positioning by voice prompts
results
• Results announced by voice prompts
• Graphic display helps to identify the contaminated
parts of the body
• Individual results of all detectors available via push
button
• Measurement results are stored in a database and
can be exported
• Full intranet access to database using CeMoSys™
(option)
servIce
Maintenance
• Standardised components for quick & easy service
• All parameters and maintenance tools available via
graphic user interface
• Information on current detector and measurement
status availbale
• Check of all binary inputs and outputs
• Light leak test to identify damaged detectors
• Quick test for single detectors with calibration sources
(option)
• Detector replacement in less than 60 sec due to
hardware simplification and «ready» in 7 min (required
for reestablishing background)
self Diagnostic
• Background count rate with minimum and maximum
alarm thresholds, special algorithm to early identify
light leakage
• Monitoring of communication between electronics
and PC, reporting error information
calibration Tool
• Single and multiple source calibration
• Calibration of one, several or all channels
• Simple recalibration after detector change
• Database for calibration sources, automatic
calculation of current activity
• Reference calibrations automatically transferred
to measurement software
• Comparision of detector efficiencies with reference
database for monitoring calibration results possible
• Results can be printed and exported to USB device
