10.6.3 For microprocessor systems, follow the manufacturer's directions for removing values from memory when the decision to discard a tear value has been made. Otherwise, for some test instruments manual calculation of the average is required. 10.6.4 If, during the test, the scale reading does not reach 20%or reaches over 80%(60%when applicable, see Table A3.1) of full scale range, change to the next lower or higher full scale range, as applicable. See 8.6. 10.6.5 Record if the tear was cross-wise to the normal (parallel) direction of tear and report that specimen, or that sample, as applicable, as untearable. 10.7 Remove the torn specimen and continue until five tears have been recorded for each test direction and test condition, as required, from each laboratory sampling unit.11.
