LLAC4 Four-Channel, Low-Level AC Conversion Module

5. Program Examples

Using the CR1000, let's measure four different wind speed sensors that produce

low-level AC signals. These will include the RM Young 05103, 05106, 05305,

propeller type anemometers, and RM Young 03101 cup anemometer. Program

examples are provided for both the CR1000 and the CR200(X).
