Data management

About stored data

The following types of data are stored in the data log:
• Sample measurements: stored automatically each time a sample is measured in the Press to
Read or Interval Mode. When the continuous measurement mode is used, data is stored only
when Store is selected.
• Calibrations: stored only when Store is selected at the end of a calibration. Calibration data is also
stored in the IntelliCAL (R) probe.
• Check standard measurements: stored automatically each time a check standard is measured (in
the Press to Read or Interval Mode).
When the data log becomes full (500 data points), the oldest data point is deleted when a new data
point is added. The entire data log can be deleted to remove data that has already been sent to a
printer or PC ( key > Delete Data Log). To prevent deletion of the data log by a user, use the
Security Options menu.

View stored data

The data log contains sample, calibration and check standard data. The most recent data point in the
