4.5 Sampling the Exhaust Gas
Once the zero calibration and test procedures have been completed and the
fuel has been selected the probe can be inserted into the desired vehicle
exhaust.
Ensure the probe is inserted into the exhaust pipe so as to not allow air into the
probe. The exhaust of a car can pulse, especially at low RPM, drawing air in
causing bad readings, ensure the flexible probe is fully inserted and the clip
attached to the exhaust pipe.
4.6 Turning the pump ON/OFF
The analyzer is fitted with a pump to draw gas from the vehicle exhaust. To
conserve battery power, switch off the pump when you are not taking a
measurement. Gas values will not be displayed when the pump is turned off .
Use the
key to turn ON and OFF the pump.
