2.2. Data Collection
Each Kaye ValProbe RT Logger collects and stores up to 100,000 data samples per sensor in
onboard Logger 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 may be programmed to start data collection manually when the Qualification is
started and programmed to stop collection manually or based on cycle time.

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