DAQmx Frequency measurement and pulse count

Hi all,

 

I want to measure frequency with my DAQ card, and it doesn´t work.

I have attached two screenshots of my VIenerate a 1kHz signal on ctr1, and...

... if I count the pulses, it wors, the READ vi gives me the number of pulses since start of the task Smiley Very Happy

... if I measure the frequency of this signal, the READ vi runs always in timeout. Smiley Sad

 

The idea how I build my application is from an example VI from NI.

My question is, how to ge measurement values when I measure frequency?

...of course there is a bridge between ctr1_out and ctr0_in.
