Time Measurement
Speed and Travel Measurement
Opening (closing) time: The opening (closing) time refers to the time from when the switch receives the opening (closing) control signal (coil energized) to when the moving contact and static contact first separate (close).
Intra-phase simultaneity: The difference between the maximum and minimum opening and closing times among contacts of the same phase.
Inter-phase simultaneity: Among phases A, B, and C, the difference between the maximum closing times of each phase is the closing inter-phase simultaneity, and the difference between the minimum opening times is the opening inter-phase simultaneity.
Bounce count: The bounce count refers to the number of times the moving and static contacts separate (close) during the opening (closing) operation.
Bounce time: The bounce time refers to the time from the first separation (or closing) of the moving and static contacts to the final stable separation (or closing).
Contact curve: The opening and closing state of the contacts, and plot the "state-time" curve;
Speed and Travel Measurement
Just opening (closing) speed: The just opening (closing) speed refers to the average speed within a specified time or distance when the moving and static contacts contact. This tester provides many definitions of just opening (closing) speed for various switches.
