Page 10: Product Description
5 Product description 5.1 Design and function The CNR 4 is a 4 component net radiometer that measures the energy balance between incoming short-wave and long-wave Far Infrared (FIR) radiation versus surface-reflected short-wave and outgoing long-wave radiation. The CNR 4 net radiometer consists of a pyranometer pair, one facing upward, the other facing downward, and a pyrgeometer pair in a similar configuration. - Page 11 CNF4 ventilation unit (optional) Cable feed-through for temperature connection Cable feed-through for sensor connection Ventilation unit connector Filter Mounting rod feed-through <11>...

9 Troubleshooting 9.1 Error elimination If the instrument does not work properly and the problem is not clear, perform an "upside-down test" as follows: ü Indoor: A lamp is available as a source of solar and far infrared radiation. ü Outdoor: – ... -
Page 21: Testing The Pyrgeometer
The range can be estimated on theoretical considerations. When the maximum expected radiation is 1500 Watts per square metre, which is roughly equal to normal outdoor daylight conditions, and the sensitivity of the pyranometer is 15 μV per Watt per square metre, the expected output range of the pyranometer is 1500 times 15 which is equal to 22 500 μV, or 0.0225 Volts. -
Page 22: Testing The Ventilator
9.7 Testing the ventilator Test the ventilator of the optional CNF4 ventilation unit as follows: 4 Check the impedance of the ventilator motor. ð The value should be around 30 Ohms. The cable resistance should measure about 0.1 Ohms per metre cable. In this case a correct value is measured this does not guarantee proper operation. -
