PocketDataLog software turns a standard pocket PC into a handheld data recorder and digitizer. Users pre-specify names, units and order of instruments to be read, as well as "out-of-bounds" values and help files. Program provides multiple screens to allow for password entry, time stamp and individual data input. Each data entry is checked for abnormal values and if appropriate, a caution or warning will be displayed. Process and Mechanical Technologies, Inc. 14781 Memorial Dr. #300 Houston, TX, 77079-5210
