QuickStart

A video that describes data logger programming using Short Cut is available at: www.campbellsci.com/videos/cr1000x-data logger-getting-started-program-part-3 . Short Cut is an easy way to program your data logger to measure the sensor and assign data logger wiring terminals. Short Cut is available as a download on www.campbellsci.com . It is included in installations of LoggerNet, RTDAQ, and PC400.

The following procedure also shows using Short Cut to program the sensor.

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 HygroVUE5 or locate the sensor in the Sensors > Meteorological > Relative Humidity & Temperature folder. Double-click HygroVUE5/HygroVUE10 Temperature & Relative Humidity Sensor. Temperature units default to degrees Celsius. This can be changed by clicking the Deg C box and selecting Deg F, for degrees Fahrenheit, or K, for Kelvin. SDI-12 Address defaults to 0. Enter the correct SDI-12 Address for the HygroVue 5 if it has been changed from the factory-set default value.

   

4. Click the Wiring tab to see how the sensor is to be wired to the data logger. The default control terminal for SDI‑12 is C1. To change to another terminal, click the terminal name and select another terminal. Click OK after wiring the sensor.

   

5. Repeat steps three and four for other sensors you want to measure. Click Next.

6. In Output Setup, type the scan rate (5 seconds or longer), meaningful table names, and the Data Output Storage Interval. Click Next.

   NOTE:

   Making measurements from the HygroVue 5 more frequently than 5 seconds can result in small additional errors due to self-heating of the element. If the main scan rate needs to be faster than this, please read Sensor measurement and Measurements in programs with fast scan rates about alternate programming techniques.

   

7. Select the measurement and its associated output option.

   

8. Click Finish and save the program. Send the program just created to the data logger if the data logger is connected to the computer.

9. If the sensor is connected to the data logger, check the output of the sensor in the data display in LoggerNet, RTDAQ, or PC400 to make sure it is making reasonable measurements.
