           16 Press again the AUTO key to start the actual test.
           17 Actual test procedure:
              •  Note  down  the  value1  appears  on  the  digital  display  indicating  that  the  unites  ready  for  the  first  free
                 acceleration test during the next 5 sec the gate to the micro processor or memory is open and scans for the
                 peak opacity and stores it.
              •  Depress the accelerator pedal smoothly and completely and keep it there.
              •  The engine will be accelerated from low idle to high idle (govern or cut off speed).
              •  Keep the engine at high idle for about 5 sec and then release the accelerator pedal. The gate to the
                 memory of the micro processor is closed for 3 sec after the initial 5 sec have elapsed. The peak value of
                 this test is indicated at the digital display.The flashing of the LED at AUTO key indicates the next cycle can
                 start.
              •  Press AUTO-key. The value 2 indicates the readiness of the unit for the second free acceleration test.
              •  Continue as pre scribed above.
              •  Repeat procedure until 3 valid free acceleration tests have been performed.
              •  Press AUTO again For 3 sec (“....”) appears then the mean value of the 3 valid test peak values is indicated
                 and the test report is printed.
           Be interrupted by not pressing the indication test for minimum 30 sec sand thus gives a protocol printout indicating
           the results of the tests taken.
           18 As the test completes you will again get the printout of the actual readings. Eg.
