2.3.10 dist. adj.   

You can specify the distance correction constant by this parameter. This product determines its 

scanning distance using the number of rotations of the wheel. Thus, wear of the wheels causes error 
in determining the scanning distance. To remove erro in the scanning distance, this product 
compensates the detected distance by using the distance correction constant set to this parameter. 
If the scanning distance has error, enter the correct distance correction constant to this parameter by 
performing the following procedure. 

 

Example of the scanning distance compensation: 

a) Perform a 1m (actual value) scan and stop the scan. 
b) Press the  4  

SET

 key to show the parameter setting screen 

c) Select the  dist.. adj  by using the 

▲▼

 cursor keys and enter the setting field by using the 

 cursor keys. 

d) Adjust the distance correction constant by using the 

▲▼

 cursor keys so as the distance value   

displayed by [    ] to the right of the distance correction constant is as close as possible to 1 m. 

e) Exit from the setting field by using the 

 cursor keys and press the  4  

SET

 key to 

return to the scan screen. 

 

 

  The scanning distance of the last scanning is displayed at the right of the distance 

correction constant. When the distance correction constant is changed, the scanning 
distance is also changed. Adjust the distance correction constant by refering this 
scanning distance value. 

 The new distance correction constant becomes effective from the next scan. The 

new distance constant is not reflected to the existing test results. 

 When setting a value 

13 to the distance correction constant , scanning the 

distance longer than 10m, and printing the scan result at the wide display range 
setting ( DW :Deep Wide,  NW :Normal Wide,  SW :Shallow Wide), the printed 
result may show a part which is difficult to read. 

 

2.3.11  output  

You can specify the destination and format of the external data output by this parameter.  The 

available settings are    printer(I) ,    CF[text] , and    CF[binary] . Also a character showing the current 
setting is displayed at the lower right of the scan screen. The table below shows the relationship 
among the setting, destination and format, and character displayed at the lower right of the scan 
screen . See Section 3.6 External output methods for the operation method. Set a desired setting to 
this parameter in accordance with the procedure described in section 2.3.
