Notes from the A2LA scope:
- 2 CMC (Calibration & Measurement Capability) is the smallest uncertainty the lab can achieve within its scope for routine calibrations of nearly ideal equipment, expressed at approximately 95 % confidence (k = 2). The actual uncertainty of a specific calibration may be larger depending on the customer’s device and conditions.
- 3 Field (on-site) calibration service is available for this calibration. Uncertainties achievable at a customer’s site are normally expected to be larger than the CMC listed.
- 4 Percentages are percentage of reading unless otherwise indicated. L = nominal length in inches, D = nominal diameter in inches, I.V. = Indicated Value.
