Issue Details

I'm acquiring a Counter Input frequency task on VeriStand and I am trying to read the frequency value on a User Interface with an indicator, but it is updating to slowly with respect to the frequency changment of the input signal, why? 

Solution

Once you ensure that the signal is effectively changing faster than the User Interface you have to check the Minimum Frequency Value on the Channel Properties of the Counter Input task:
That value set the minimum time you have to wait before the frequency value can update (expressed by the period of the frequency): increasing the Minimum Value, the frequency value on the User Interface will update faster.
