(Gas sampling and multi-position valves only)

GSV: Specify the default valve position as defined in the Valves submenu of the GC configuration. Available values: 0 (= 'Load') or 1 (= 'Inject').

Multipos: Specify the number of positions of the multi-position valve. The accepted range is from 2 to 255.

If the GC is shared between two timebases, the first four valves are assigned to the 'left' timebase, while the remaining valves are assigned to the 'right' timebase.
