VU01 manual v1614 6/25
VU01 is designed, using high-quality materials, in agreement with the recommendations
of ISO/TR 9901 and BSRN. The footprint of VU01 is small, which prevents accumulation
of snow. The ventilator power is relatively high in order to increase the airflow. The
heaters should be activated using external relays. A fan status signal (high / low) may be
used by the user to monitor rotation of the fan.
For specifications of pyranometers and pyrgeometers and general considerations
concerning site selection and maintenance fur such instruments, please consult the
SR20, SR20-D2, SR22, SR25, SR25-D1 and IR20 manuals.
