Electronic time clock P

For measuring short time intervals, with quasi-analogue 0.01 second display consisting of 100 LEDs arranged in a circular array. Full seconds indicated on luminous digital display.
Timing started and stopped either dynamically, i.e. the inputs (START and STOP) respond to rising and failing edges (edge-sensitive), or statically, i.e. the input (START/STOP) responds to the state (state-sensitive). This enables timing of either intervals between two events of the duration of an event.
Timing can also be started and stopped manually using the integrated switch. Switches or electrical pulse generators can be used for external control, e.g. a light barrier at a DIN socket or a contact plate or microphone at the 4-mm sockets.
The electronic time clock can either be used as a bench-top unit or inserted in the demonstration experiment frame (301 300).
