I agree with John's concern and suggest that a decision to retest should be made only after determining how far the equipment was out of cal and if that error could have changed the results.

Is this applied 'with mind engaged'? If a piece of equipment is found to be 1 dB out of calibration, do you have to re-test everything, even if its results were, say, 10 dB or more under the limit? -- OOO - Own Opinions Only.
