Many VOMs will measure AC and DC Current up to 20 amps. And you hook it in series with the load.
AC clamp meters can measure without disconnecting the wiring.
"What does "Full Load Amps 7.6/3.7-3.8" mean?" --- That is the 120 and 240 Volt rating.
FLA is the Max power the motor will pull under full load when running.
Start current will be a bit higher, until the motor comes up to speed.

Theory only works perfect in a vacuum.
