Page 13: Sampling The Exhaust Gas
4.4 Sampling the Exhaust Gas Once the zero calibration and test procedures have been completed and the fuel has been selected (See Section 5.2.2) 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. -

Page 27: Problem Solving
The following is a list of problems that may occur on the instrument through its operating life. If the cause of the fault is not easy to identify then we advise you contact UEI International Technical Support or an International Distributor for expert advice. -
Page 28: Zero Checks And Re-Calibration
If you suspect the internal filter is blocked perform the following: • Remove the probe connection from the water trap. • Empty and clean the water trap with a dry cloth. • Fit a new external particle filter. • Run the instrument in fresh air (pump ON) for at least one hour. If the problem does not clear contact a service agent. -
Page 29: Hc Residue Check (Certain Analyzers Only)
10.2 HC residue check (Certain analyzers only) Hydrocarbon is a very ‘sticky’ gas and can cling to tubing in the analyzer or probe. If HC % vol reading does not go below 20 ppm when in fresh air following a test then a residue check will be requested. Repeat tests will be carried out until the reading is below 20 ppm. -
Page 30: Leak Check
10.3 Leak Check To ensure the gas sampling system is sealed correctly and not letting in air, the analyzer will perform a leak check. This requires the user to block the probe inlet and perform the test. This check is done every time the analyzer is switched on or as requested by the user. -

Page 33: User Re-Calibration
Once the analyzer has detected a stable gas supply it will check that all the gas readings are within the allowable deviation from the factory calibration. If the readings are within these limits it will proceed to the next section 10.4.3 User Re-calibration. Note! Disconnect gas at this time. -
Page 34: Printed Calibration Report
Before the new calibration can be accepted an authorization code is required. Enter each number of the code 5128. ENTER SERVICE CODE 5 1 2 8 Once the last digit has been entered the analyzer will store the new settings into its memory, this may take a few seconds and you will be asked to PLEASE WAIT. -
Page 35: Reset Instrument Calibration
Information contained on the calibration report is as follows: • VERSION: Analyzer software version • CO, CO2, HC, O2, NO: Gas readings as measured during check. • MAX / MIN: Upper and lower limits at which calibration check fails and re- calibration is advised. -
Page 36: Product Specification
Enter each digit of the code as explained in Set Up Menu (Section 5.2.5). Once the last digit has been entered the factory settings will be restored and the analyzer will return to the main display. A calibration check should now be performed. If the wrong code is entered the analyzer will exit to the previous menu without restoring the factory settings. - Page 37 PRODUCT SPECIFICATION FOR HANDHELD AUTO4-2 AND AGA5000 Parameter Resolution Accuracy Range Carbon Monoxide 0.01 % +/- 5 % of reading 0-10 % (Infrared) +/- 0.5 % volume Over-range: 20 % Oxygen 0.01% +/- 5 % of reading 0-21% (fuel cell) +/- 0.1 % of reading Over-range: 48% Hydrocarbon...

Page 40: Procedure For Changing Oxygen Fuel Cell
A simplified formula, derived from the basic formula, and based upon the assumption that the water content of the fuel and air and the NOx content in the exhaust gases are negligible, allows the computation of Lambda when certain components of the exhaust are measured. Oxygen balance formula For Lambda calculation, based upon measurements of CO, CO2, HC and O2, the following formula is standardized: Displayed on the instrument as LAMBDA (O) - Page 41 UEi shall not be liable for loss of use of the instrument or other incidental or consequential damages, expenses, or economic loss, or for any claim or claims for such damage, expenses or economic loss.
