(A2LA Cert. No. 1560.01) 10/09/2025 Page 4 of 4 3 Field calibration service is available for this calibration. Please note the actual measurement uncertainties achievable on a customer's site can normally be expected to be larger than the CMC found on the A2LA Scope. Allowance must be made for aspects such as the environment at the place of calibration and for other possible adverse effects such as those caused by transportation of the calibration equipment. The usual allowance for the actual uncertainty introduced by the item being calibrated, (e.g. resolution) must also be considered and this, on its own, could result in the actual measurement uncertainty achievable on a customer’s site being larger than the CMC. 4 In the statement of CMC, L is the numerical value of the nominal length of the device measured in inches, T = torque measured value, and R is the numerical value of the resolution of the device under test in µin. 5 In the statement of CMC, percentages are to be read as percent of reading unless otherwise noted. 6 This scope meets A2LA’s P112 Flexible Scope Policy.
