2.2. Data Collection
Each Kaye ValProbe RT Logger collects and stores up to 100,000 data
samples per sensor in memory at a user-specified sample rate. If the
Loggers reaches 100,000 samples then the Logger stops collecting any
further data. Data stored in the Logger is stored in non volatile memory and
is retained until a new Qualification or Verification is loaded.
Loggers can be programmed to start data collection manually when the
Qualification is started or based on Time of Day and programmed to stop
collection manually or based on cycle time.

Cycle Time
Time of Day cannot be programmed for more than 72 hours after the Loggers
are programmed. After 72 hours, the Loggers are set to shelf mode if a study
is not started.
Cycle Time does not have any duration limit, cycle time duration depends on
the sampling rate and number of samples. The maximum number of samples
that can be collected is 100,000 per sensor.
