| Résumé : |
Hand held dry film thickness (DFT) gages are common inspection tools used by applicators and inspectors. With a little care and maintenance, mechanical and electronic instruments can be relied upon to give many years of accurate and dependable service.
Good operation begins with reading the manual. All instruments have subtle operational differences. Record the make, model, serial number and date of purchase inside the manual and highlight maintenance and calibration tips. |
| Note de contenu : |
- Can I calibrate ?
- It's vital to verify
- Influential effects
- Edge cases
- Roughly adjusting for profile
- Accumulations errors
- Inspect your probe
- Holding the probe
- One is seldom enough
- FIGURES : 1. A certificate of calibration - 2. A sample calculation - 3. Surface profile usually results in higher readings - 4. The accuracy of an adjusted gage changes from +1% to +5% as calculated using a root sum of the squares formula - 5. For best results and longest life, the sliding probe should not be gripped high, but instead with your fingers low to the surface |
