4. Auxiliary Instrument(s)

- Specialized cleaning solution and towel

5. Conditions for Calibration

- Temperature: (23 ± 5) °C

- Humidity: no higher than (50 ± 15) %RH

6. Prepare for Calibration

Prior to the calibration, the following preparations must be done:

- Prepare the standard instrument

- Select the suitable standard instrument to calibrate the caliper.

- Use the cleaning solution and specialized wipes to clean the surface of the standard instrument.

- Place standard instruments in the calibration room for temperature stabilization for at least two hours.

Prepare the caliper to be calibrated:

- Clean the caliper and its jaws with industrial gasoline or equivalent solvents.

- Place the caliper near the standard instrument in the calibration room for at least two hours to stabilize the temperature before performing the calibration.

7. Begin the calibration

7.1 Outside Check

7.2 Technical Check

7.3 Measurement Check

7.3.1 Identify the accuracy of the caliper

- Outside measurement

- Inside Measurement

7.3.2 Check the deviation of the jaw

- Outside jaws

- Inside Jaws

8. Reliability Evaluation

9. General handling

a. The calibrated caliper is stamped, certified in paper along with calibration results, and measurement uncertainty.

b. The recommended calibration cycle of digimatic caliper is 12 months.
