Remove the battery if storing the Cyclops 7 Logger for extended periods 1 2 A Few Details The previous section gives instructions for sampling at 10 minute intervals However there are a few additional details that will enhance use of the Cyclops 7 Logger Sensor cover The sensor guard is the long tube having slots in the end that covers the Turner C7 sensor This guard not only protects the sensor but also establishes a consistent field of view for the sensor The guard must be used when the sensor is calibrated and also when it is used for measurements in the field Sampling rate The Cyclops 7 Logger records measurements at equal time intervals The default time interval is 10 minutes If a formatted SD card is placed in the Cyclops 7 Logger and the power is turned on then the logger will record every 10 minutes However it is also possible to instruct the Cyclops 7 Logger to record at different intervals This is accomplished by connecting a Windows computer to the logger and using software supplied for this purpose See Chapter 2 Sample intervals of less than 1 minute or longer than 1 hour are not allowed and will be rejected by the Cyclops 7 Logger software The Cyclops 7 Logger will flash its LED repeatedly if it encounters a sample interval request outside this range Sample Time The Cyclops 7 Logger records the time that each is made It does this based on an internal clock When your Cyclops 7 Logger arrives it is se
