ABSTRACT:
An instrument having a continuity test feature wherein a change in continuity state from open-to-short or short-to-open is captured and displayed. A comparator provides continuity state information for a circuit under test. A storage device receives the state information and provides logic indicative of the continuity state which is read by a controller that executes a continuity capture program initiated by keypad or function selector input. A first transition between different continuity states is captured during a present capture cycle and is displayed in a form indicative of the type of transition captured. Subsequent transitions during the present capture cycle are ignored.
