ADS FlowShark HV O&M Manual

Modifying the Parameter Settings 

The lower level screens provide access to parameter settings that may be modified to 
provide additional information, compensate for flow conditions, support associated 
hardware, and address other relevant issues involved in velocity measurement 
activities.  The default parameters are set for the FlowShark HV at the factory.  Under 
normal conditions, it should not be necessary to access or modify the parameter 
settings on the control unit. 

Warning!

  Making changes to the parameter settings requires a 

comprehensive understanding of the equipment and settings because it can 
have a significant impact on the outcome and accuracy of  the velocity 
measurements.  Therefore, please contact a regional ADS representative for 
assistance before setting or modifying any parameters on the FlowShark HV.
