Why is the temperature reading shown by my Vaisala Transmitter too high?
The temperature reading may be too high because the transmitter is installed in an unsuitable location, such as near a heat source or in sunlight. Use a portable reference meter to check this. For HMW82 and HMW83 models, ensure that the transmitter is installed in the proper orientation, with the arrow on the mounting base pointing up.
What to do if my Vaisala INTERCAP HMDW80 outputs an incorrect humidity reading?
If your transmitter outputs an incorrect humidity reading: * For models with probes: check if the yellow transport protection cap has been left over the probe. Remove it if present. * For models with a configurable output parameter: check that the desired output parameter has been selected using the DIP switches.
What does ERROR HUM mean on my Vaisala INTERCAP HMDW80 Transmitter?
The ERROR HUM message indicates a problem with the humidity sensor. Check if the humidity sensor is damaged or missing.
What does ERROR T mean on my Vaisala INTERCAP HMDW80 Transmitter?
The ERROR T message indicates a problem with the temperature sensor. Check if the temperature sensor is damaged or missing.
Why is the current output on the temperature channel ~24 mA on my Vaisala INTERCAP HMDW80?
If the current output on the temperature channel is approximately 24 mA, check that the humidity output channel is powered. For loop-powered HMDW80 series models that measure humidity, the humidity output channel must be connected, even when only measuring temperature.
What does INTERNAL 1 INTERNAL 2 INTERNAL 3 mean on my Vaisala Transmitter?
If you see 'INTERNAL 1 INTERNAL 2 INTERNAL 3', it indicates an internal problem with the transmitter. Restart the transmitter to see if the problem remains.
