(14) If the gap between the maximum and the minimum of exhaust emissions density
tested three times is larger than 5% or the final test result is over the acceptable
limits for exhaust emissions, an additional test will be done once more automatically
and up to maximum 5 times. In every test, if the calculated result of the last three
tests is within the range of 5% gap and the average result is within the acceptable
range, the test will be ended with the display of “PASS” and each time you press
[SET] KEY, the screen will be changed to show the test result of the first, the
second and the third test in their average(Avrg) and difference(Diff).
When you press [PRINT] KEY, you will get prints and you can print the same prints
until you press [ACCEL] KEY.
Even after the 5 times of repeated tests, if the gap between the maximum and the
minimum is larger than 5% or the average result is over the acceptable limits for
exhaust emissions, the final test result will be the average of the last three (3th, 4th,
5th) tests, you will see “FAIL” on the display and the test will be ended
automatically.
