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 uncerta inty 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. Field environmental conditions are limited to 15 °C to 30 °C and <80% relative humidity to 30 °C. 4 Fluke 5520A CMCs are based upon the temperature the standard was calibrated (tcal ± 5 oC) and assuming the instrument is zeroed at least every seven days or when the ambient temperature changes more than 5 oC. For Resistance, a zero calibration is performed at least every 12 hours within ± 1 oC of use. For AC Current, CMCs are determined with the LCOMP off and ON. CMCs are also based upon 1-year floor specifications. CMCs are expressed as either a specifi c value that covers the full range or as a fraction of the reading plus a fixed floor specification. 5 Agilent 3458A CMCs are based upon the temper ature the standard was calibrated (tcal ± 5 oC) and an auto calibration (ACAL) was performed within the previous 24 hours (± 1 oC of ambient temperature.) CMCs are also based upon 1-year floor specifications . CMCs are expressed as either a specific value that covers the full range or as a combination of a percent or the fraction of the reading/output plus a range specification. 6 In the statement of CMC, percentages are percentages of reading, unless otherwise indicated. 7 Applicable when the internal time base (oscillator) of the device under test is/can be measured directly by the frequency counter. 8 In the statement of CMC, L is the numerical value of the nominal length of the device measured in inches. 9 The type of instrument or material being calibrate d is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter. 10 This scope meets A2LA’s P112 Flexible Scope Policy.
