Damn good meter
Just a very good, featureful and reliable multimeter. It works great with or without a PC. Auto ranging is great and if you leave the dial turned on without doing anything it'll eventually shut off to save the battery. You can also plug it in and it has a nice compartment in the side to hold the test leads, power cord etc.

It's a little bulky if you're primary intention is to use it for portable on-the-go stuff. But it works well either on the bench or as a portable unit otherwise.

Excellent for the price. You'd generally have to pay more for something comparable.

As advertised
This multimeter does everything as advertised, it also operates plugged to the 120 VAC outlet or use 6 AA batteries, and or a single 9 Volt batt (has space and connection for both at the same time) .
The software runs on Windows 98/NT/ME/2000/XP but I have Vista and have no problem. RS232 output is a serial port, so I use a KEYSPAN adapter to connect to a USB port and run seamless (sold by Amazon too).
The software is to record the actual reading at interval time from 1 second to 3600 seconds. I use to monitors the RMS voltage of my power generator for 6 hours and gave me a graphics too. Exporting to Excel is in csv format, that is why I didn't give a 5 star.
Solid construction, accurate for the bench work, and also portable. I use a strap that came with it to hang in front of me, and leave both hands free to test vertical electric control panels on the field.

A serious meter with RS232
Thanks Kaito ! This meter works great with all features. I use the protocol to write my code and load the data from the port, works well.
Highly recommend it.

Thanks!
