Set up test parameters:
Press the “MODE” button until the “PEAK” option is displayed and press
“ENTER”. Follow the screen prompts.
If the AUTO600 has performed a peak
smoke test since it was switched on the
handset will start a zeroing sequence.
Follow the on screen prompts until the
handset displays the current vehicle
category. This may be changed by
using the “UP”, “DOWN” and “ENTER”
keys.
Select the measurement units required
using the “UNITS” key and press
“ENTER” to confirm.
Select the number of smoke tests to average using the “UP” “DOWN”
and “ENTER” keys. The choice is three or five peaks.
At this stage the AUTO600 summarises the test parameters on the
screen.
The screen then displays the key actions needed to stop and start the
smoke test sequence. It is very important that the probe is fitted into the
running vehicle’s exhaust before the “ENTER” key is pressed to start
testing. The AUTO600 monitors the vehicle’s idle smoke emission and
uses this to detect when the engine is accelerated. If this sequence is not
followed false smoke triggers and unreliable readings will result.
Starting the test sequence:
CAUTION:
Ensure the vehicle is at normal operating temperature,
particularly its oil temperature, and the engine is running!
Insert the probe into the exhaust.
Press the “ENTER” key to start the test and press the “UP” and “DOWN”
keys at the same time to end the test. A test can only be terminated at
the end of the “5 4 3 2 1” countdown. It is only at this point that the full
smoke information is available.
