SCADAR data loggers are intentionally designed with simplicity of operation and long battery life in mind, they therefore do not feature complex cable interconnects or a complex user interface.  Logger software is intuitive and therefore requires no operator intervention.  Instead, once a data logger is armed (completion of the Base to Logger step using your SCADAR Base station) it's working!  So how do you know if its actually doing something...

An explanation of condition feedback follows...
