The EL-USB-5 constantly logs event and state changes such a rising edges (voltage going from low to high) or falling edge (a voltage going from high to low).
Pen-shaped, easy-to-use and fully configurable using a PC and the built-in USB connector, this datalogger can store information on events and state changes alongside date and time data. Up to 32510 events and state changes can be recorded and up to 32,510 timed intervals can also be stored in event counter mode.
This logger is capable of capturing events at a speed of two times per second and state changes at speeds of up to four times per second. The event counting function can operate at speeds of up to 100 times per second and adjustments can be made to logging rates by configuring the logger on PC.
A set of measurement leads terminated with crocodile clips and a long-life lithium battery (which will last for around a year) are included with this datalogger.
