Appendix E. Verifying Measurement Tips

Verify measurement tips each time you use them to ensure that no mechanical
damage has degraded their accuracy. Visual iQ systems are shipped with
a measurement verification block. This tool lets you verify the accuracy of
measurement tips. It contains optical measurement targets whose accuracy is
traceable to the United States National Institute of Standards and Technology (NIST)
measurement standards.
These are the part numbers for the verification blocks used with the Visual iQ:
VER2400C For 4.0 mm systems
VER2600D For 6.1 mm systems
To Verify a Stereo or 3DPM Measurement Tip:
Step 1
– A stereo tip must be securely connected and identified (using the Global
Menu). A 3DPM tip need only be securely connected, then select Verify as shown here.
Step 2
– Insert the tip into the appropriate verification block. For 3DPM tips, continue
to follow the on-screen prompts until verification is complete. Note that the results of
this automatic verification are logged in a file for troubleshooting (if required).
Step 3
– For stereo tips, measure the test target that matches the units you use:
inches or mm (click here to learn more about making Stereo Measurements).
Step 4
– Evaluate your results
An experienced user can achieve a measurement of 0.100 ± 0.005 inches (1.00 ± 0.05
mm). If your measurement does not fall within these limits, try the suggestions under
Troubleshooting Measurements.
Each measurement verification block comes with a calibration schedule and a
certificate of calibration (C of C), which notes the calibration date and due date.
