VOLTCRAFT SEM5000 DUAL Energy-Logger Bedienungsanleitung Seite 66

9 Operation
A Supercap condenser is integrated into the energy logger, which
is used to operate/program the device without having to plug it
into a mains socket (for around 10 minutes).
The capacitor is usually in an uncharged state upon delivery/
start-up. Therefore, the energy logger can only be operated/pro-
grammed when it is plugged directly into a mains socket upon
start-up.
You can unplug the energy logger from the mains socket and
program it, e.g. in sufficient light in the living room or office, only
when the capacitor is sufficiently charged (after around 50 min-
utes).
For energy saving reasons, the display backlight only works when
the energy logger is plugged into a mains socket.
If the energy logger is operated without plugging it into a mains
socket and the super-cap capacitor becomes empty, the time is
lost. You must then set these again.
The energy logger shows the current consumption even without
an SD card inserted. This is indicated by a green light on the
LED ring (8).
Unplug the energy logger from the power socket
To insert the SD card, pull out the cover (10), insert the card and
push it back into the housing and plug the energy logger into a
power socket. Then the blue light flashes. You have to set the
time so that the data can be stored on SD card. Make sure the
SD card (not included) is inserted before using the energy logger
to log the measured data. Now the blue light on the LED ring (8)
flashes. You must set the time so that the data can be saved on
