Amp/HV
Amp/HV...enter the detector manufacturers recommended high voltage value, click on On/Off to desired position. Set
Course and Fine Gain by either entering number or by moving sliding scale. Click on desire Conversion Gain. Set LLD
and ULD by either entering number or by moving sliding scale. When all setting are entered click on OK, this will set the
adjustments and exit menu to spectrum screen.
Preset
Presets provides to establishing data acquisition termination criteria. Time or counts limits may be defined.
Preset Live Time provides automatic correction for counting losses caused by the system deadtime. Events which occur
during the pulse processing cycle are lost to the system so the timer is automatically updated to compensate for these
losses. When operating at excessively high count-rates the deadtime meter will indicate a high value and the real counting
time may be more than doubled. Increasing the LLD setting can help reduce some high deadtime effects.
Preset Real Time sets the counting timer to run for actual clocktime and makes no correction for losses due to deadtime
effects.
Preset Peak Count
Counting will terminate when the content of any channel in the entire spectrum reaches the preset value.
Preset Integral Count
To set an integral count it is necessary to first establish a ROI and then position the marker within the region. Counting
terminates when the desired counts is collected in the ROI.
Spectrum
Spectrum...Switches the display to Spectrum if the user has been in either Peak or Data Report mode.
Peak Report
Peak Report...If regions of interest have been set around peaks in a spectrum, the Peak Report provides a convenient
method of displaying peak information in tabular form. Readout will be in energy units if the energy calibration is active.
