Digital Counter For event counting, a fixed counting period can be programmed in a range from 0.1 ms to 99999 s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.
Nexpensive, compact counter for measuring milliseconds. Each count is started and stopped by a signal at the input sockets. The device is automatically reset to zero each time it is restarted.
