CSAT3 Three Dimensional Sonic Anemometer CAUTION Command/Option 90, 91, 98, or 99 must not be used to collect data from a CSAT3 running a cold shifted calibration, see Section 11.2.1. Option 1, 2, 3, 5, 6, 10, 12, 15, 20, 30, and 60: "Set Execution Parameter" tells the CSAT3 which measurement parameters to use and what frequency to expect the measurement trigger from the datalogger. The datalogger Execution Interval and the appropriate CSAT3 Execution Parameter is summarized in TABLE 10-3 and TABLE 10-4. Option 61 and 62: "Set Execution Parameter" tells the CSAT3 to oversample (Section 8.1.2) the wind measurements at a rate of 60 Hz and expect a trigger at a rate of 10 Hz (option 61) or 20 Hz (option 62) from a CR3000, CR1000, CR5000, CR800/850, CR9000(X), CR23X or 21X datalogger. Option 51 and 52: "Set Execution Parameter" tells the CSAT3 to oversample (Section 8.1.2) the wind measurements at a rate of 48 Hz and expect a trigger at a rate of 8 Hz (option 51) or 16 Hz (option 52) from a CR10(X) datalogger.

CSAT3 Three Dimensional Sonic Anemometer
Command/Option 90, 91, 98, or 99 must not be used to
collect data from a CSAT3 running a cold shifted
calibration, see Section 11.2.1.
Option 1, 2, 3, 5, 6, 10, 12, 15, 20, 30, and 60:
“Set Execution Parameter”
tells the CSAT3 which measurement parameters to use and what frequency to
expect the measurement trigger from the datalogger.
The datalogger Execution
Interval and the appropriate CSAT3 Execution Parameter is summarized in
TABLE 10-3 and TABLE 10-4.
Option 61 and 62:
“Set Execution Parameter” tells the CSAT3 to oversample
(Section 8.1.2) the wind measurements at a rate of 60 Hz and expect a trigger
at a rate of 10 Hz (option 61) or 20 Hz (option 62) from a CR3000, CR1000,
CR5000, CR800/850, CR9000(X), CR23X or 21X datalogger.
Option 51 and 52:
“Set Execution Parameter” tells the CSAT3 to oversample
(Section 8.1.2) the wind measurements at a rate of 48 Hz and expect a trigger
at a rate of 8 Hz (option 51) or 16 Hz (option 52) from a CR10(X) datalogger.
