Use the analyzer touch screen to turn on and off datarecording before beginning to drive.• If using the analyzer in a moving vehicle, make sure the exhaust hosesdischarge out the window. The analyzer’s exhaust contains poisonous exhaustgas that must be ventilated to a safe space.✓ Connect the long hose to the system exhaust and place it outside thevehicle. Do not pinch the hose.• If a significant amount of data is stored in a pocket PC, periodically deletecustomers and data.• Certain gases are produced only when driving a vehicle under certainconditions. NO x is typically generated only when a car is under load. Generally,when testing a car for emissions, many garages attempt to simulate the test thatis conducted in their local state.• The Analyzer must be oriented on a flat surface. Low flow may occur when theanalyzer is sitting on a severe incline. The float in the water trap / filter bowl mayshut down the unit if tipped excessively.• If the analyzer is used where a very high level of hydrocarbons and water exists,hydrocarbon (HC) hangup may result. HC hangup is present if you are samplingair and HC registers a value. Running the pump for an extended period of timeafter use in this type of environment causes the condition to clear.4-12
