Log and analyze data from your Radio Shack serial multimeter (model 22-812). Data is logged and time-stamped to a text file in your pocketPC. Select the interval to collect data, from once every 300ms to once a day. Export the comma delimited text file to a desktop PC, or send it via email. Connect your pocketPC to the meter with a serial cable and null-modem adapter, or use a Bluetooth adapter on the meter if your pocketPC supports BT. http://www.geocities.com/prestonsystems/ for details and instructions.
