Andrzej: I use both Isodat 2.0 and 2.5 versions. I have sequence pre-scripts that do nothing but start a timer. I use it to start runs overnight so that it is just finishing my initial few priming samples when I get in in the morning. Also good for timing a carbonate flushing sequence to start overnight and finish just before arriving. It doesn't collect data, so there is no wasted data file. And no separate methods are required. The sequence simply starts after the set time. It is a simple script with the _Delay() function in the body. The number of milliseconds of delayed time is entered between the brackets. Milliseconds are a pain to use, but at least it works. --Alison ________________________________ Alison Pye . [log in to unmask] Stable Isotope Lab Coordinator CREAIT . TERRA Facility .

Dear Listmembers, using ISODAT 2.82, I would like to start a measurement sequence with a time shift meaning, that it would start at a given time, or alternatively, after a given period of time. Could somebody advise me on how to do it?
