The following guidelines are intended to show an easy method for determining whether currently-reported data is acceptable. These guidelines represent the minimum you should do to verify the recorded measurement values are consistent with expected and historic values. Perform additional checks as necessary.

To check the acceptability of hourly data, verify the system clock was not changed during the measurement hour. If the system clock was changed, the Minutes field displays double asterisks (for example,11** ).

During a partial system reset (for example, 1 or 2 or Cold 1 or Cold 2) the measurement data is retained for the affected time interval. However, during a full system reset (for example, 3, 4, or 5) the measurement data is not retained for the affected time interval.
