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.
