385 to 2105 nm. The CS320 provides onboard storage of digital calibration data and has a digital SDI-12 output that can be read by most Campbell Scientific data loggers. A detachable cable allows easier field servicing.

1. Open Short Cut and click Create New Program. 2. Double-click the data logger model. 3. In the Available Sensors and Devices box, type CS320 or find the sensor in the Sensors > Meteorological > Solar Radiation folder, and double-click CS320 Digital Thermopile Pyranometer.

5. Repeat steps three and four for other sensors you want to measure. Click Next. 6. In Output Setup, type the scan rate, a Table Name, and Data Output Storage Interval. Click Next. NOTE: Because of the delays using SDI-12, Campbell Scientific recommends measurement scans of 10 seconds or more. CS320 Digital Thermopile Pyranometer...
Ideally, the X, Y, and Z measurements should be zero. Tilt in any direction changes the Z-axis measurement. If the Z-axis measurement is greater than 1.0 or less than -1.0, the CS320 needs to be leveled. With the appropriate data logger CS320 Digital Thermopile Pyranometer...
CS320 is no longer level, which can affect the accuracy of the global radiation measurements. The CS320 has an SDI-12 output, where shortwave radiation is returned in digital format.
(p. 1), for a Short Cut tutorial. 7.1 Siting The CS320 should be mounted such that no shadows or reflections are cast on it by the tripod/tower or other sensors. Mounting the CS320 on a crossarm can help avoid reflections from the tripod or tower mast.
NOTE: You can also use a CM225 or 015ARM to mount the CS320 to a tripod or tower. However, a leveling base is required. The installation procedure for using the CM225 and 015ARM mounts is available in an older manual at www.campbellsci.com/old-manuals.

6. Route the sensor cable along the underside of the crossarm to the tripod/tower, and to the instrument enclosure. 7. Secure the cable to the crossarm and mast using cable ties. 8. Remove the green cap after installing the sensor. Save this cap for shipping or storing the sensor. CS320 Digital Thermopile Pyranometer...
For the CR6 and CR1000X data loggers, triggering conflicts may occur when a companion terminal is used for a triggering instruction such as TimerInput(), PulseCount(), or WaitDigTrig(). For example, if the CS320 is connected to C3 on a CR1000X, C4 cannot be used in the TimerInput(), PulseCount(), or WaitDigTrig() instructions.
(p. 16) for more information. 8. Operation The CS320 is a thermopile pyranometer.Thermopile pyranometers use a series of thermoelectric junctions to provide a signal of several μV/W/m proportional to the temperature difference between a black absorbing surface and a reference. The reference may be either a white reflective surface or the internal portion of the sensor base.
CS320 thermopile uniformly absorbs solar radiation across the shortwave solar spectrum from 385 to 2105 nm. 8.1 SDI-12 measurements The CS320 responds to the M!, M1!, M2!, M3!, M4!, C!, C1!, C2!, C3!, C4!, and ?! SDI-12 commands. CS320 SDI-12 commands (p.
Use the XHON! SDI-12 command to turn the heater on and the XHOFF! SDI-12 command to turn the heater off. Campbell Scientific recommends only powering the heater when frost or condensation is likely to occur. The most convenient method for doing this is to have the data logger program turn the heater on and off based on air temperature measurements and dewpoint calculations.

(by more than 6%), the sensor should be cleaned and re-leveled. If measurements are still different after a second test, contact Campbell Scientific to discuss test results and possible return of sensor(s). Refer to the Assistance (p.

SDI-12, Serial Data Interface at 1200 baud, is a protocol developed to simplify sensor and data logger compatibility. Only three wires are necessary — serial data, ground, and 12 V. With unique addresses, multiple SDI-12 sensors can connect to a single SDI-12 terminal on a Campbell Scientific data logger.
For example, to change an address from 0 to 2, the command is 0A2!. The sensor responds with the new address b, which in this case is 2. NOTE: Only one sensor should be connected to a particular terminal at a time when changing addresses. CS320 Digital Thermopile Pyranometer...
