I'd imagine it is a 32 bit signed int, with a maximum value of 65535.
I understand that you can get the current sample time for a particular
mode using I1_GetOption("2009") [Should be around "0.010" for Rev A, and
about half that for Rev B or Rev D), and the total measurement time should be
be that number times the I1_TriggerCountedScan() parameter.

I think sip* is for a different instrument (one of the Sequel Chroma
colorimeters ?).
