What to do if my Vaisala HUMICAP HMT360 displays 'ERROR'?
If your Vaisala Transmitter displays the word 'ERROR', it could be due to connection issues or moisture. First, check that the sensor is connected properly. If the sensor is connected properly, check if there is condensed water in the probe and allow the probe to dry.
Why is the LED on my Vaisala Transmitter lit when no calibration is in progress?
If the LED on your Vaisala Transmitter is lit when no calibration is in progress (for transmitters without a display), it may be due to connection issues or moisture. Check that the sensor is properly connected. Also, inspect the probe for any condensed water and allow it to dry completely.
What to do if the analog output current drops below 4 mA on my Vaisala HUMICAP HMT360?
If the analog output current on your Vaisala Transmitter drops below 4 mA, ensure that the sensor is properly connected. Additionally, check the probe for any condensed water and, if present, allow the probe to dry thoroughly.
