ABSTRACT:
A digital tester includes structure for: automatically effecting AC/DC determination of an input signal and subsequent AC/DC switch-over of a measurement system, enabling high-response measurement; measuring a pulse width using a simple construction and having high reliability, by handling changes in an input potential as changes in potential zones; and storing the probes and test leads so that the digital tester is easier to handle for a higher degree of convenience in use. The storing of the probes enables each probe to be securely stored with the grooves; to enable the probes to be used in their stored positions; and to facilitate removal of the probes by a user.
