Creating A Short Cut Data Logger Program - Campbell CR300 Series Getting Started Manual

4. Creating a Short Cut data
logger program
You must provide a program for the data logger in order for it to make measurements, store
data, or control external devices. There are several ways to write a program. The simplest is to use
the program generator called Short Cut. For more complex programming the CRBasic editor is
used. The program file may use the extension .CR300, .CRB or .DLD.
Data logger programs are executed on a precise schedule termed the scan interval, based on the
data logger internal clock.
Measurements are first stored in temporary memory called variables in the Public Table. Variables
are usually overwritten each scan. Periodically, generally on a time interval, the data logger stores
data in tables. The Data Tables are later copied to a computer using your data logger support
software.
Use the Short Cut software to generate a program for your data logger. Short Cut is included
with your data logger support software.
This section will guide you through programming a CR300 series data logger to measure the
voltage of the data logger power supply, the internal temperature of the data logger, and a
thermocouple. With minor changes, these steps can apply to other measurements. Use the
following instructions or watch the
1. Using data logger support software, launch Short Cut.
LoggerNet users, click Program then Short Cut
l
PC400 and PC200W users, click Short Cut
l
2. Click Create New Program.
3. Select CR300 Series and click Next.
NOTE:
The first time Short Cut is run, a prompt will ask for a noise rejection choice. Select 60
Hz Noise Rejection for North America and areas using 60 Hz ac voltage. Select 50 Hz
Noise Rejection for most of the Eastern Hemisphere and areas that operate at 50 Hz.
A second prompt lists sensor support options. Campbell Scientific, Inc. (US) is usually
the best fit outside of Europe.
