Dear Andrzej:

We also use a dummy method of, say, 3600 seconds (1 hour), and run
however many times we need. If you want to reduce the size of the
resulting file, change the sampling rate to 10 seconds or more (rather
than the many default which is many times per second.)

You can also make use of the waiting time to monitor mass 18 or mass 40,
if either of those is of interest.
