save counter input data against time

[suffyzull]

Hello, i would like to know about recording using a write to measurement file.
When i record a data like analog input, at the save file with display the analog data against time.
But when i tried to applied for the encoder, which is using counter input, in the .txt file dont display
the result as analog input. So can someone give me a guide on what to setting on write to measument
file to measure the revolution per minute rotation against time, thanks

There is no setting for the Write Measurement File. Your problem is that you are passing a scalar to the function and that scalar has no timestamp information. When you use an analog acquisition, the data type is either a waveform or dynamic data type. Below is one way to add the timestamp information. You also should have a delay or msec wait in your loop. This can be used for the dt information.
