CMP3 Pyranometer 

Cross check this serial number against the serial number on your 

pyranometer to ensure that the given sensitivity value corresponds 

to your sensor.  

4. QuickStart

A video that describes data logger programming using 

Short Cut 

is available 

at: 

www.campbellsci.

part-3

Short Cut 

is an easy way to program your data logger to measure this 

sensor and assign data logger wiring terminals. 

Short Cut

 is available as a 

download on 

www.campbellsci.

eu

. It is included in installations of 

LoggerNet

RTDAQ

PC400

, or 

PC200W

The following procedure also describes programming with 

Short Cut

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 CMP3 or find the sensor

in the 

Sensors

 > 

Meteorological

 > 

Solar Radiation

 folder. Double-click

CMP3/CMP6/CMP11

 

Pyranometer

. Default units are kW/m

2

 for flux

density units and kJ/m

2

 for total flux. These can be changed by clicking

the 

Flux Density

 and 

Total Flux

 boxes and selecting different values. A

sensitivity value needs to be entered. This value is unique to each sensor

and is listed on the calibration sheet that is included with the sensor.
