[Novalug] anyone have any experience with home power usage measurement

[James (Jim) Darlack]

I recently looked at an online catalog... JAMECO?  And it had several RS-232 capable meters.  
   
  Maybe search google for meter serial or meter rs-232.
   
  The Radio SHack one, has improved ranges and can read diodes and transistors.  I used it to test the amp hours on a battery.  For my previous company.  I lauhged when they thought it would be an expensive undertaking.  Radio Shack meter, old PC with Microshaft Windows, and a few wires.  Hardware minus PC and Microshaft, < 100.
   
  Here is a sourceforge article on the Rad Shack meters:

  Hmm... I just searched Rad Shack and didnt see the digital multimeter with a serial interface.  I know Fluke makes one, and a higher price.  But I also know there are  cheepies out there for hobbyist usage.

  now there's an idea. i did look on radio shack before mailing this
list, but i couldn't find that device. i'll clearly look again now
that i know someone else remembers such a device there. what would
you search on? "ammeter" or "clamp-on" are definitely not it.
