FP-CTR-500 and Frequency Measurement: How to modify it to report the frequency (0-10 Hz) every one minute?

[JeffLi]

How to modify "Frequency Measurement" to report the frequency every one minute?  

The signal frequencies vary from 0 to 10 Hz (see the analog output plot and attached sample data file), so I want record the average frequency every one minute. 

Software: Labview 8.5 

Hardware: FP-CTR-500

Program: "Frequency Measurement"  --build in and under "NI example finder", It was attached with this message. 

Physical wiring: (1) The signal I want to measure to count input 1 (pins 2 and 18).  it is a pulse signal (range from 0 to 1 V, see the plot and attached data file). 

 (2) Wire Output 0 (pin 130 to gate 0 (pin 9).   Do com pins 26 and 30 need to wire together? 

FP-CTR-5000 was set up in Max based on the program instructions. I have tried different gating pulse frequency, my readings are always "0".

CTR-500 high pulse is >=10V. Hence, it always read your pulse as low. With this low voltage pulse, you must use analog input module, and write a program to read pulse from analog level. You must also make sure that you pulse is not so narrow that cFP loop is not fast enough to capture voltage change.
