How can I find absolute value of fata recorded from channel?

[mujo]

Hi, I am a fresh user of DIADEM. Can somebody help me to find absolute value of fata recorded from channel?

First channel is time and second is absolute vibration. I want to find abs(vibration).

That is a calculation which can easily be dine with the calculator tool (fount on the toolbar in the DIAdem modules VIEW, ANALYSIS, and SCRIPT.
Just open the calculator and enter Ch("Abs") = abs(ch(2)). This will create a new channel containing the absolute values of channel number two - you can use the original time channel for drawing this curve in a diagram.

Thanks for answer but I still have a problems.

I think calculator can not work with channels. I got a message that I am sending in attachment.

Hello Emir,
it seems you are not using the actual version of DIAdem. We changed the syntax of commands in the calculator to VBS lately.
To make it work in your environment you would have to replace the = with := (= is reserved for comparisons in the old AUT syntax).

That would make the command:  ch("Abs") := abs(ch(2))

regards
