    4 支計數器, #1,#2,#3,#4, 分成三組,  分隔的距離如上圖所示. 各支的工作狀態如下表.   

 

  #1 #2  #3  #4 
工作電壓 0.880 0.810  0.692  0.882 
單一通量值(cnts/sec) 24  25  25  22 

 

 

以指令 WC 00 N1N2 取得數據可以分成3組, 是因為計數器之間的三種距離, 5cm,35cm, 70cm:

 

N1N2 (5cm) 13           
計數值 (cnts/sec) 8.1  
   
   
N1N2 (35cm) 15  16  1C  27     
計數值 (cnts/sec)  2.5  3.0  2.9  2.5     
N1N2 (70cm) 19  1A  2B 2D 2E  3F
計數值 (cnts/sec)  1.0  1.1  0.9  1.0  1.0  0.9
