Mounting the Transmitter with Optional
Rain Shield
If you mount HMT310 outdoors, use a shelter to protect the transmitter.
An HMT310 rain shield is available from Vaisala as an optional
accessory (order code ASM211103).
NOTE Vaisala does not recommend installing the transmitter outdoors with the
smaller mounting plate (without flanges). Use the larger mounting plate
with flanges for outdoor installations.
