Measure the voltage of the device's power supply unit. The appropriate value is around 24V.
Measure the resistance in the channel of the I/O module, on which the pyranometer/thermometer is connected
If the resistance is around 50Ω, that means that there is no problem with the module's channel and the cabling must be checked.
If the resistance is over 50Ω, then there is a problem with the specific channel and the pyranometer/thermometer is most probably needed to be put in another spare channel of the I/O module, but this will not happen until it is ensured that the voltage that is returned to the channel from the device is safe and acceptable.
Measure the voltage in the channel of the I/O module, on which the pyranometer/thermometer is connected.
If the voltage is between 0,2 - 0,9 Volt, that means there is no problem with the module's channel and the cabling must be checked.
If the voltage is not between 0,2 - 0,9 Volt, follow the same procedure as in the resistance measurement (contact us in order to consult you about a spare channel in the I/O module).
If the pyranometer is completely shaded, the correct value is 0,2V.
If all the measurements are as expected, our support team must be informed in order to make the appropriate software changes.
