When the instrument status dialog is expanded (
>>more
button is
pressed), a graph showing current particle concentration similar to the
instrument front panel is displayed. Control the data displayed in the graph
in the following ways:
Press the
Start Sampling
button to begin sampling. The graph will
begin updates of current particle concentration once per second.
Linear
or
Log

the two y-axis scales.
dN/dlogDp

Analog Out
The Analog Output Setup dialog displays the output voltage and the EEPS
Model 3090 Analog Out settings. If the dialog is active, it shows the current
3090 settings. If the current document is an old data file with Analog Data
included, the
Properties | Analog Out Tab
will display the Model 3090
EEPS Analog Out settings state at the time the EEPS data file was
created. If the Analog Out dialog is accessed from the Instrument Status
dialog, it will always be active and display/adjust the current Model 3090
settings. If the Model 3090 does
not
have the
Analog Out
option or the
data file was taken with a Model 3090 without the Analog Out feature, the
Analog Out dialog will not be available. The information entered is
immediately sent to the Model 3090 when data entry is completed. For
direct entry, this is after the
Enter
key,
Esc
key, or
Tab
key is pressed.
Invalid entries will leave the previous value for that field unchanged.
Note:
Cancel does
not
restore the Model 3090 EEPS spectrometer to any
previous state. The Model 3090 Instrument Analog Out settings
have already been updated by the time
Cancel
is pressed.
Save these Settings…
button. Brings up a file dialog box where all of
the values currently set will be saved in a Settings (*.set) file that can
be used later to restore the Model 3090 settings back to the current
settings.
Load Settings from a File…
button. Brings up a file dialog box where
previous Model 3090 settings can be used to restore the Model 3090
settings back to a previous saved state. File type is *.set.
