Beskrivning
It stores the data together with time and date in accordance with the set memory cycle.
In addition, measuring data of an LNM (5.4110.xx.xxx) can be acquired and stored.
The read-out of the stored data is carried out directly via the serial interface, USB,
or by means of an SD-card. Date, time, station name, and memory cycle can be set via 3 keys.
The instrument can be operated in battery-supplied mode (mains-independent).
The pulses of the precipitation transmitter can be processed potential-free via opto-coupler
