AR100 Operation Manual

 

35 

Sxxxxx 

Sampling period 

1) 10 - 65535, (default: 5000) 
When laser is set to Time Sampling mode (TSx) this is the time 
interval (in increments of 1 μs)  
2) 10 - 65535, (default: 5000) 
When laser is set to Trigger Sampling mode (TSx) this is the 
division for the external synchronization input 

Note:

 See section 8.6 for further explanation 

Exxxx

 

Maximum integration time 

2 - 3200, (default: 3200) specifies the limiting time of integration 
by CMOS-

array (in increments of 1 μs)

 

Dxxx 

Time lock of result 

0 - 255, (default: 1) Specifies time interval the sensor will output 
last valid result in increments of 5 ms 

Zxxxxx 

Zero point 

0 - 

16383, (default: 0) specifies zero point within sensor’s 

measurement span
