3 NOTES Reading this entire manual is recommended for a full understanding of this product. The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying the instrument. Kipp &...
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.
5.2 Top view All connection are done on the top The provided connectors have the possibility to tie the cable to the strain relief. 6 Meteon connections DC IN ANALOG PULSE MODBUS 12 VDC DATA 6.1 DC IN Beside batteries the Meteon can be operated on external DC power. When using the Mencke & Tegtmeyer temperature sensor this is a must, because it requires 12 VDC.

the Pulse input menu. If the energy is generated by a number of PV panels, the number of square meters of your panels can be set as well. In this way the total amount of kWh per m is calculated. Because only one connection per S0 output can be made, the Meteon also as an output to connect this to a second device, without blocking further use of the S0 port.
On the Modbus input multiple Modbus devices can be connected. Up to 5 Smart radiometers and a M&T temperature sensor. Of course they have to be configured with identical communication settings and different Modbus addresses. The Smart sensors can be powered by the Meteon 2.0 when this option is enabled in the Configuration menu.
6.5 Batteries Changing the batteries can be done by pressing the 2 buttons near the bottom on both sides of the housing (indicated with red arrows) At the same time the lid closing the battery compartment can be pulled off. The last battery becomes visible and the battery holder can be pulled out. Five AA alkaline batteries are required to supply the METEON with 7.5 Volt.

11 Keyboard functions The On/Off – Back key will turn on the Meteon after a short press and turn off after a long press (>1 second, and only when in top level menu). When on, a short press will go one level up. The backlight key will toggle the LCD backlight.
When the USB cable is connected at power on, or during operation and logging is off, the menu asks you to select between: 12.1 PC communication This sets normal operation with the possibility to use the Meteon 2.0 PC software. See chapter 16 for a detailed description. 12.2 Transparent This sets the Meteon to act just as an RS485 to USB interface.
13.2 Pulse input Here the number of pulses per kWh can be set. These pulses are normally generated by an inverter or kWh meter that is connected to a number of solar panels that covers x m . In this way the generated energy per m can be calculated and compared with the incoming radiation from the pyranometer.
Example of Comparison report A good comparison requires the two sensors to be mounted side by side, either horizontal or both the same orientation and angle. No obstructions are allowed and a clear sky is required. For a useful result it takes at least a few hours around noon, but better is to measure a full day. Keep in mind that an outdoor calibration of a pyranometer according to the ISO 9847 standard requires a 2 to 3 days period with clear sky, or longer for cloudy conditions.
16 PC software For connecting the Meteon 2.0 to the PC, a mini USB cable is supplied. The Software can be downloaded from the METEON 2.0 product page. When connecting it either finds the Meteon 2.0 directly or a COM port has to be selected where to Meteon is connected.
16.1 Start Screen The bottom line of the start screen shows if a Meteon is found on one of the available COM ports, if not, the sub-menu [Connect using..] offers the option to pick one of the available COM ports by hand. Sync METEON Date and Time with PC, transfers the PC Date and Time settings to the Meteon.
16.2 Data Explorer screen When downloading the data from the METEON it is visualized with the above Data Explorer screen. This graph with auto scaling shows the selected sensors as selected in the top left corner. When sensors are not required they can be deleted with by deleting the checkmarks in the top left section. In the registration menu (bottom left corner) one of the downloaded registrations can be selected.
16.4 Preferences screen Here the default folder for downloaded data can be set, as well as the colors used per sensor. The Calibrations tab to define a location to store calibrations is not used at this moment.
16.5 Sensor list The above list comes as standard with the METEON but can be edited by the user. When a new (analog) sensor needs to be added this can be done by pressing the + field and entering the relevant data for this sensor. By clicking in one of the cells, the present data can be altered. With [SAVE TO METEON] the new sensor list can be transferred to the METEON memory.
