About the Measurement Tips
Unlike standard optical tips, 3D PhaseProbe
measurement tips are factory-calibrated for use with specific probes and will not measure
accurately with other probes. These tips are matched to probes by the serial numbers
identified on each optical tip and each probe label. Calibration data is stored in memory in
the probe.
To ensure measurement accuracy, check each tip's calibration every twelve months.
To display the calibration data, press
or Stereo or Shadow > Cal Info.
To ensure that no mechanical damage has degraded their accuracy, verify measurement
tips each time you use them. See
To learn which tips are available for which probes, see
About the MTD Number
The 3D Phase Measurement system will display a number on-screen after a
measurement is complete. While taking the measurement, an MTD number will appear
(see the lower left corner of the figure below). MTD stands for Maximum Target Distance
and is the distance from the 3D Phase Measurement tip to the surface at the point of the
active cursor. 3D Phase Measurement systems do not use Accuracy Index.
