   A quick Variac + KAW check on a small bench grinder (no load) gave   
   about half the current and VA readings at 80VAC as at 120VAC, without   
   audibly slowing it down much. It would take me a while to set up and   
   test a household appliance motor. They jump when started unless   
   clamped down.   
      
   The KAWez measured voltage down to 45VAC, where the LCD fades out.
