Common use of Meter Calibration Clause in Contracts

Meter Calibration. (A) Calibration must be carried out to the relevant product standard with tests at the load points specified in Table 1 of these TSRs, in accordance with the accuracy requirements set out in Table 2 and Table 3 of these TSRs. (B) The relevant product standards are BS EN 62053-22 (Active static Meters of Classes 0.2S and 0.5S), 62053-11 (Active electromechanical Meters of Classes 0.5, 1 and 2), 62053-21 (Active static Meters of Classes 1 and 2), or 62053-23 (Reactive static Meters of Classes 2 and 3)). (C) Calibration Certificates must include a measurement uncertainty evaluation which shall be determined to a confidence level of 95 per cent. or greater in accordance with the UKAS Directive M3003. Measurement uncertainties for Meters must be within the limits set out in Table 4 of these TSRs. (D) No compensation shall be applied to any Meter pursuant to these TSRs or the MOF. (E) Calibration will be conducted using the Meter’s metrological test output. However, for at least one load point, it shall also be confirmed that the physical display and the pulse output, where used for purposes of the CfD Settlement Activities, are registering to the necessary standards of accuracy (i.e., all outputs fitted give the same measurement result).

Meter Calibration. (A) 4.1.1 Calibration must be carried out to the relevant product standard with tests at the load points specified in Table 1 of these TSRs, in accordance with the accuracy requirements set out in Table 2 and Table 3 of these TSRs. (B) 4.1.2 The relevant product standards are BS EN 62053-22 (Active static Meters of Classes 0.2S and 0.5S), 62053-11 (Active electromechanical Meters of Classes 0.5, 1 and 2), 62053-21 (Active static Meters of Classes 1 and 2), or 62053-23 (Reactive static Meters of Classes 2 and 3)). (C) 4.1.3 Calibration Certificates must include a measurement uncertainty evaluation which shall be determined to a confidence level of 95 per cent. or greater in accordance with the UKAS Directive M3003. Measurement uncertainties for Meters must be within the limits set out in Table 4 3 of these TSRs. (D) 4.1.4 No compensation shall be applied to any Meter pursuant to these TSRs or the MOF. (E) 4.1.5 Calibration will be conducted using the Meter’s metrological test output. However, for at least one load point, it shall also be confirmed that the physical display and the pulse output, where used for purposes of the CfD Settlement Activities, are registering to the necessary standards of accuracy (i.e., all outputs fitted give the same measurement result).
