5.2 Edlog Examples
Example 3 is a portion of a CR10(X) program, but our CR500, CR510, and
CR23X dataloggers are programmed similarly. Wiring used for the CR10(X)
program is included in Table 3.
Example 4 is an Edlog program written for a 21X Micrologger; wiring used for
the 21X program is included in Table 3. The 21X program turns on control
port 1 to power the CS210. Notice that the scan rate is set at 10 seconds. The
sensor won’t give a good reading until the second scan.
