.
- Press the key
4
again to store the "+SET" value.

8.2 Data logger (measured value memory) with real-time clock
The BENNING SUN 2 can store up to 5000 data records consisting of the values for insola-
tion (solar irradiance), module temperature and ambient temperature. Each data record will be
provided with a time / date stamp. The measuring data can be read out via the integrated USB
interface and by means of a download software. The measuring interval (time between two
measurements) of the BENNING SUN 2 can be set from 1 minute to 60 minutes in increments
of one minute.
8.2.1 Data logger set-up
The set-up allows the user to set the measuring interval, the memory mode and to delete all
data records.
- Press the key
7
for > 5 seconds to call the data logger. "LOG" appears on the digital display
2
.
- Alternately, the display shows the occupied / free memory space as well as the battery
voltage / the measuring interval in minutes.
- To set the measuring interval (1 minute to 60 minutes), press the key
7
again for > 5
seconds. Display: "Int". Press the key
4
or key
5
to increase or decrease the value in
increments of one minute.
- Press the key
3
to display the memory mode. Display: "dAtA". Press the key
4
or key
