Counter timer problems

‎03-23-2005 03:22 PM

Can anybody tell me how I can get around a problem I have with double counts. I am using a counter that is connected to a photocell to count objects as they past the photocell. However, I am getting several false counts that I want to eliminate, is there a way I can specify the minimum time that the counter must be high before it counts?

DrMarty,

Some DAQ boards (660x family, M-series) support digital filtering for counter tasks. Do you have one of these? If so, check the online help and search for examples to try to get started.

On the other hand, do you have something more like an E-series multifunction board? That may be trickier... I don't have a specific solution in mind (yet), but there might be a way... Post back with the type of DAQ board you have.
