Ground Check Box

The ground check box is used to check the radiosonde sensor accuracy and to set the frequency of the radiosonde. The ground check box includes high precision humidity sensor and temperature sensor as humidity and temperature reference, when in checking the radiosonde sensors are compared with references. If the difference between radiosonde sensors and references is out of the acceptance, the Radiosonde is regarded to be defective.
