3.9.15  Optional setting  
 
Operation environments are set on the Optional Setup dialog window.   
To open the Optional Setup dialog window, select the Optional Setup command from the 
Option menu or click the Opt Setup button 
  on the tool button area of the operation panel. 
.The dialog window has 5 tabs. Each has functions as follows. 
 
(1) General tab : general setting 
 
(a) RASTER ROTATION area 
WD-Rotation selection specifies if the image rotation 
caused by the objective lens magnetic field is 
compensated automatically or not. For normal 
operation, it is strongly recommended to enable the 
automatic compensation function. 
(b) LOW MAG MODE area 
Select the highest magnification in the Low Mag 
Mode. Use [x2k] for usual operation. [x10k] is only 
for special requirements. Image distortion caused by 
field magnetic disturbance may appear at 
magnification higher than x2k. 
(c) MICRON MARKER area 
When Sizable is selected, the length of the micron 
marker will be adjusted so as the length indication do not have fraction. 
If Fixed is selected, the length is fixed to 30mm on 4x5 inches photograph. In this case, 
the length value indication some times has fraction, especially by coarse focusing. 
(d) DATA ENTRY / MEASUREMENT area 
Select font and size to be used in Data Entry and CD Measurement. 
(e) PRINT SIZE 
Set the size of images when placed on a page using Windows application software. The 
setting is effective only on application programs those support the X and Y-Resolution 
tags of Tiff files or equivalent header of DIB files. The Aldus Page Maker supports TIFF 
files and MS Word also DIB files.   
4x5 Photo Size button sets the value just same as photograph size. 
(f) SIGNAL SELECT 
When the U/L SED Ratio Variable box is checked, in Mix mode the gain ratio of upper 
and lower SE detector is kept to which upper and lower detectors are used 
independently. It is effective to control ratio of signals detected by both detectors.   
If it is not checked, ratio of both two detectors is even. In this case upper detector signal 
will be dominant at short working distance and lower detector signal at long working 
distance. The latter may be easier to usual operation.
