Introduction
The METEON 2.0 is a compact handheld data logger specialized for PV related Solar Radiation
measurement. It is supplied in a small carrying case that has also room for a pyranometer with cable. It
accepts simultaneously up to 5 Smart and one analog Kipp & Zonen pyranometers plus a Mencke &
Tegtmeyer PV panel temperature sensor. An S0 input / output for kWh meter or Inverter pulses and an
USB port are present. The large 8 x 22 character display is readable in full sunlight and has back light
for low light conditions. The keypad with 7 keys can be used to navigate through the different menus.
When using the UBS connection the METEON 2.0 can be set in transparent mode to act as a universal
RS-485 interface for the connected Modbus sensors. The Internal batteries (5 x AA) provide the
METEON and the Smart radiometers with power. For a M&T temperature sensor an external power
supply (12 VDC) has to be connected. The Meteon can measure, display and log up to 8 devices.
Depending on the log interval it logs up to weeks of data. Comparison of pyranometers is possible with
one as reference instrument. Log files are transferred to the PC via the USB interface. Log data can be
visualized and/or exported to a csv file with the free available software. Instruments, time and settings
are copied in the header of each file.
