ANUAL
MicroVario is a sensitive altimeter/variometer which uses the latest MEMS technology to achieve a high level of
accuracy, while preserving miniature dimensions. The sensor is able to detect tiny changes in atmospheric
pressure to indicate the climb/sink rate.

NSTALLATION
Connect the MicroVario directly to the receiver telemetry port. Please note that the sensor is very sensitive to
changes in atmospheric pressure and also to mechanical stress. To reach the most accurate altitude
measurements please pay attention to the receiver placement. Try to avoid any mechanical stress on the
sensor. The MicroVario should not be directly exposed to the airflow and any close contact with components
producing heat (such as engines or speed controllers) should be avoided.
