automatically. The “NFC” icon N is briey shown on the LC display
1
.
- After having called (RECALL) a storage location from the measured value memory of the
BENNING PV 2, rst press the
1
-key
K
to switch over the LC display
1
and write the
curve data to the NFC chip. The “NFC” icon N is briey shown on the LC display.
- As soon as the “NFC” icon N disappears, hold the NFC antenna of your Android device as
close and still as possible over the NFC logo
8
on the top of the BENNING PV 2 housing.
- The I-V characteristic will be transferred to the Android device and displayed.
Notes on data transfer:
- Protective pouches or covers of your Android device might affect data transfer. Remove
them before transferring data, if necessary.
- In the settings of your Android device, disable Android Beam, Samsung Beam or other
beams. The setting might affect NFC data transfer.
- Do not hold the Android device over the NFC logo
8
as long as the “NFC” icon N is shown
on the LC display
1
. Transfer might be impaired.
- If you do not know from the respective manual where the NFC antenna of your Android
device is located, slowly move the Android device over the surface of the BENNING PV 2
to establish a connection. Some Android device use the NFC logo on the housing surface
to locate the NFC antenna, whereas in other devices, the NFC antenna is located within the
battery area.

8.8 Radio connection to insolation / temperature measuring instrument BENNING SUN 2 –
wireless SUN link
The BENNING PV 2 is able to receive the measured values (insolation, PV module / ambient
temperature and date / time stamp) of the insolation and temperature measuring instrument
BENNING SUN 2 (optional) via radio connection.
For this purpose, the BENNING PV 2 has to be coupled with the BENNING SUN 2 once.
Typical radio range of the BENNING SUN 2 in open space: approx. 30 m
Buildings / metal structures or interfering signals can reduce the radio range.
8.8.1 Coupling with BENNING SUN 2
- Remove all electronic devices in direct vicinity.
- Switch the BENNING PV 2 and the BENNING SUN 2 off.
- Press and hold the two ON/OFF keys of the BENNING SUN 2.
- Press and hold simultaneously the
R
ISO
-key
4
and the
Mode
-key
5
of the BENNING PV 2.
- The BENNING PV 2 indicates the successful coupling by means of an acoustic signal and
by displaying the serial no. of the BENNING SUN 2.
- The "W/m
2
" symbol is shown on the LC display
1
of the BENNING PV 2.
8.8.2 Decoupling from the BENNING SUN 2
- Remove all electronic devices in direct vicinity.
- Switch the BENNING PV 2 off.
- Press and hold the
R
ISO
-key
4
and the
Mode
-key
5
of the BENNING PV 2 for approx. 10
seconds.
- The BENNING PV 2 indicates the decoupling from the BENNING SUN 2 by means of an
acoustic signal and by clearing the LC display.
- The "R
PE
/Ω" symbol is shown on the LC display
1
of the BENNING PV 2.
8.8.3 Activating / deactivating the radio transmission of the BENNING SUN 2
- Couple the BENNING PV 2 with the BENNING SUN 2.
- To activate / deactivate the radio transmission, press and hold the -key of the
BENNING SUN 2 and simultaneously press the -key. A flashing triangle above the
-key shows that the radio transmission has been activated.
- If the BENNING PV 2 is within the radio range of the BENNING SUN 2, the measured insola-
tion value (W/m²) is shown on the LC display
1
of the BENNING PV 2.
- Besides the electric variables (Vo/c, Is/c, R
ISO
), an AUTO measurement by means of the
BENNING PV 2 additionally measures the insolation, the module and ambient tempera ture
as well as the date / time stamp of the BENNING SUN 2.
- If the BENNING PV 2 is outside the radio range of the BENNING SUN 2, the "W/m²" sym bol
on the LC display
1
starts flashing. Moreover, "_ _ _ _" is shown on the LC display
1
, if the
measured insolation value is outside the measuring range.
See gure 11: Radio connection to the optional insolation and temperature measuring instru-
ment BENNING SUN 2
Note:
If the BENNING PV 2 does not receive any radio signal from the BENNING SUN 2, the display
indications are stored with the date / time stamp of the BENNING PV 2.
