Calibration, Verification and Adjustment
Calibration, Verification and Adjustment
Three steps ensure best accuracy...
1. Calibration - typically performed by the manufacturer. All probes
include a Certificate of Calibration.
2. Verification of Accuracy - typically performed by the user on
known reference standards such as the included test disk.
3. Adjustment - to a known hardness
Calibration
Calibration is the high-level, controlled and documented process of
measuring traceable calibration standards over the full operating
range of the probe, and verifying that the results are within the stated
accuracy of the probe. Calibrations are performed by the
manufacturer, their authorized agent, or by an accredited calibration
laboratory in a controlled environment using a documented process.
Verification
Verification is an accuracy check performed by the user on known
reference standards. A successful verification requires the Gage to
read within the combined accuracy of the probe and the Test Disks.
Instrument operation may be verified with the included Test Disks and
Leveling Plate. Position the Leveling Plate under the Leg and place the
Test Disks on a flat, hard surface (as shown). Take three to five
readings on each disk. The measurement points should be at least
6mm (0.24") apart. If the average of those readings is outside the
combined accuracy of the Test Disk and gage, service may be
required.
