• 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.
