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
2
. In this way the generated
energy per m
2
can be calculated and compared with the incoming radiation from the pyranometer. See
section Meteon connections how to make the physical connection to the pulse input.
13.3 Temperature sensor
This sets the Modbus address for the Mencke & Tegtmeyer temperature sensor. The Test sensor
option let you check the connection and Modbus setting.
13.4 Analog sensor
In this menu an analog sensor can be selected. Selecting the sensor sets the nominal sensitivity, but
this has to be adjusted to the value of the connected instrument. Testing this sensor will always pass,
but when nothing is connected will give a low or zero reading.
13.5 Smart sensor
Here a maximum of 5 Modbus sensors can be set. Once the Modbus address is set, the Meteon will
check what type of Radiometer is connected and show the correct name.
14 Measurement
3 types of measurements can be selected
14.1 Measurement without logging
This menu will show the data from the connected sensors. The Left/Right key will skip through the
different sensors if more than one is connected.
The display will show the actual value plus hourly, daily and weekly integrals.
14.2 Logging
During logging the same measurement information screens are displayed but there is one extra
Logging active screen that shows the status of the memory and the selected interval. Here also
Left/Right keys will skip through the different sensor screens.
14.3 Differential Measurement
This is a special measurement type to compare a reference sensor and a device under test (DUT)
The DUT is compared over a period of time with an identical or better known good sensor to verify the
operation and sensitivity (calibration) of the DUT. It is not a real calibration but this test can be used to
decide if a calibration is required.
Both the reference sensor and the DUT have to be set in the Configuration menu.
