6-6  SVP Controller Operation Manual   Part No.: 44200004 - Revision 2
 
When either optical switch is triggered on the downstream pass, the SVP 
controller will drop White to 0VDC for 25mS and the CIU will instruct the 
proving program to start or stop recording meter pulses. After the run is 
complete the CIU will return to idle conditions until the next run command 
is sent.
  6.2.3  Daniels 
Actual terminal locations for the Daniel flow computer is dependent upon 
the application software being used in the Daniel flow computer. See the 
appropriate Daniel manual and software information for more information. 
 
Warning
Due to scan speed, the 2500 has limitations in flow rate when used 
with small volume flow provers due to short time period between 
volume detectors.
