the equipment listed in table 2 is not available. the items selected must be verified to
perform satisfactorily prior to use and must bear evidence of current calibration. The
equipment must meet or exceed the minimum use specifications listed in table 2. The
accuracies listed in table 2 provide a four-to-one ratio between the standard and TI. Where
the four-to-one ratio cannot be met, the actual accuracy of the equipment selected is shown
in parenthesis.
