___________________________________________________________
1
This laboratory offers commercial and field calibration service.
2
Calibration and Measurement Capability Uncertainty (CMC) is the smallest uncertainty of measurement
that a laboratory can achieve within its scope of accreditation when performing more or less routine
calibrations of nearly ideal measurement standards or nearly ideal measuring equipment. CMC’s
represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually
using a coverage factor of k = 2. The actual measurement uncertainty of a specific calibration
performed by the laboratory may be greater than the CMC due to the behavior of the customer’s device
and to influences from the circumstances of the specific calibration.
3
Field calibration service is available for this calibration and this laboratory meets A2LA R104 – General
Requirements: Accreditation of Field Testing and Field Calibration Laboratories for these calibrations.
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
Based on using the standard at the temperature the Fluke 5520A with SC600 was calibrated (tcal ± 5 °C)
and assuming the instrument is zeroed at least every seven days or when the ambient temperature
changes more than 5 °C. For resistance, a zero calibration is performed at least every 12 hours within ±
1 oC of use.
5
Based on using the standard at the temperature the HP 3458A was calibrated (tcal ± 5 °C) and an autocalibration (ACAL) was performed within the previous 24 hours (± 1 °C of ambient).
6
In the statement of CMC, the value is defined as the percentage of reading unless otherwise noted.
