Coating Data Loggers: Check Clock Alignment Before Correlating Events

A logger clock that differs from the job record can make an environmental event appear to occur before or after the wrong application stage. Check time alignment before drawing a causal conclusion.

Updated · NANOLAB Knowledge

The key distinction

Preserve the original timestamps and document any justified correction separately. Time zone, clock drift and manual clock changes can all affect the comparison between records.

Practical checks

  1. Record the logger's time basis.
  2. Compare it with a reliable reference and the job timeline.
  3. Document any offset used in analysis.

Example

Illustrative example: a humidity rise appears to coincide with coating application, but the logger clock is thirty minutes ahead of the workshop record. Correct alignment changes the event sequence that the team needs to investigate.

Scope and limits

Do not shift timestamps to fit a preferred explanation. This guide does not establish causation; it helps ensure that the evidence describes the actual chronology accurately.
