   Put the KAW first.   
      
   We tested four of these (KaW) units against NBS traceable kWh standards   
   (0.1% max error..correctable to 0.02% CF) and they were right on the money,   
   surprisingly enough. They were checked at the usual kWH meter standards =   
   100% and 50% PF and 2/3  and 10% scale,  but harmonic response was not   
   testable, at that time.   
      
   Very impressive for a $20 gadget.

   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.
