UnknownMaxCounts=100000000

 

OnPeakCountTime=10.0

This option specifies the default on peak counting time for both standard and unknown quantitative samples. The allowable range is 0.01 to 1000 seconds. The default value is 10 seconds.

 

OffPeakCountTime=5.0

This option specifies the default high and low off-peak counting time for both standard and unknown quantitative samples. The allowable range is 0.01 to 1000 seconds. The default value is 5 seconds.

 

PeakingCountTime=8.0

This option specifies the default spectrometer peak counting time for the Probe for EPMA interval halving, parabolic or ROM based peak methods. If a spectrometer pre-scan is specified, then Probe for EPMA uses a count time of 1/4 of the PeakingCountTime for the spectrometer wavelength pre-scan acquisition. The allowable range is 0.01 to 1000 seconds. The default value is 8 seconds.

 

WavescanCountTime=6.0

This option specifies the default spectrometer wavelength scan counting time for the Probe for EPMA for normal wavescans. The allowable range is 0.01 to 1000 seconds. The default value is 6 seconds.

 

QuickscanCountTime=0.5

This option specifies the default spectrometer wavelength scan counting time for the Probe for EPMA for "quick" spectrometer wavescans. The allowable range is 0.01 to 1000 seconds. The default value is 0.5 seconds. Note the following parameters apply to non-ROM based and ROM based quick scan parameters:

Non-ROM scan based

1.  Wavescan: # of points, wave count time

2.  Quickscan: Spectro scan speed (%), quick count time

ROM scan based

1.  Wavescan: # of points, wave count time

2.  Quickscan: Spectro scan speed (%), quick count time

 

UnknownMaxCounts=100000000

This option specifies the default maximum counts for unknown samples (that is precision based counting). The allowable range is 1000 to 100000000 seconds. The default value is 100000000 counts.
