To check that both inputs on an ATS are on the same phase, you'd use a
voltmeter on the Hot wire on both inputs and check that the voltage is
zero I imagine. But would you set the voltmeter to DC (because you're
looking for in-phase difference on an AC signal) or AC?
AC.
Yes, the voltage would be zero if they're on the same phase, otherwise
you'd see 208-240VAC if they're on different phases.
