CMP6-L, CMP10-L, CMP11-L, and CMP21-L Pyranometers In CRBasic, the conversion to resistance is entered as a mathematical expression. In Edlog, Instruction P59 (Bridge Transform) does the conversion. The Steinhart-Hart equation is used to convert resistance to temperature. The Steinhart-Hart equation for converting resistance to degree Celsius is as follows: Temperature = 1/[A + B*LN(resistance) + C*(LN(resistance))^3] - 273.15... -

Page 31: Changing The Desiccant
Changing the Desiccant A desiccant-filled drying cartridge prevents dew from forming on the inner sides of the domes; Campbell Scientific part number 27052 is the replacement desiccant for this cartridge. The optional CVF3 or CVF4 Heater/Ventilator Unit is also available to keep the pyranometer dome free from ice and dew (see Appendix A, CVF3, CVF4 Heater/Ventilator). -
Page 32: Recalibration
The calibration of the pyranometer may drift with time and exposure to radiation. Recalibration every two years is recommended. The sensor should be returned to Campbell Scientific for recalibration. A Returned Materials Authorization (RMA) is required (refer to the Assistance page for more information). - Page 33 CMP6-L, CMP10-L, CMP11-L, and CMP21-L Pyranometers...

Fit the pyranometer in the upper plate of the CVF3 (see Figure A-4). Use the counter sink screws, nylon rings, and nuts to secure the upper plate of the CVF3 with the lower portion of the unit (see Figure A-4). - Page 37 CVF3, CVF4 Heater Ventilator A-5 CVF3 installed onsite Tighten the mounting screws to secure the assembly in its final position. Check that the pyranometer is still correctly leveled and adjust as necessary. Use the cover’s screws to fasten the white cover to the pyranometer (see Figure A-6).
