The ET-41 Electronic Stop clock has a 4 digit LCD display and records times in either milliseconds (ms) or seconds (s) to 0.001 s. The display changes from MS to S automatically during the execution of an experiment. One or two photogates can control the clock, providing the option of timing the interruption of the gate or the time of passage between the two gates. The clock has two input jack connectors on the front of the panel (P1 and P2), providing power for two photogates as well as receiving signals from them. The front panel incorporates a reset button, recall button and on/off toggle power switch. The memory feature of the stop clock is provided for use with a single gate. In this mode, timing begins with interruption of the gate.
