Counter very low frequency using PCI-MIO-16E-4

[Conky]

Hi,

I am trying to use a PCI-MIO-16E-4 board with BNC-2090 to CI Freq. Because the frequency of our counts sometimes lower than 1Hz, even zero in the setting measure time,  the vi program always shows "Error-200527" and tells me the min frequency must be greater than 1.192Hz. Whether this board cannot measure very low frequency(even zero) in the setting measure time? If it can, how? Could you show me some examples? Thank you very much.

What measurement method are you using for your frequency measurement?  Are you able to set the minimum to 0 (it defaults to 2 which would be the rounded version of 1.192).  You may also want to try using one of the other measurement methods and see if that helps.  All of these values can be set with the Create Channel VI.
