Mark record


An electronic caliper with an optical encoder was developed for forest research studies. Connected to TRS-80®, model 100 portable computer, by "BCD" interface, this caliper permits the computerized errorfree dbh-date collection and storage in random access memory (32 K), by pressing of a simple button. Information such as species height and defects can be manually entered on the keyboard. The data can be reviewed, edited and analysed by application BASIC programs directly in the field, eliminating manual data transcription.
