EXHAUST GAS DIAGNOSTICS
As with all safety related products, there is a need to demonstrate the traceability of a product's calibration to National Standards and where appropriate to comply with IS09000 protocols. This can only be accomplished using 'live' traceable calibration gasses in accordance with manufacturing specifications and often requiring the use of bespoke test and calibration equipment.
It isn't the cold that affects the readings, it is a sudden change in temperature. We recommend that the Gas Analyzer is stored in a property rather than a vehicle during the colder months.
As a general rule of thumb, you should wait until all the readings are stable - approximately 1 minute after inserting the sampling probe into a vehicle that has reached full operating temperature.
The exhaust gas readings from diesel exhausts very widely depending on the type of engine management system. A five gas analyser will accurately measure the following gases: Oxygen, Carbon Dioxide, Carbon Monoxide and Oxides of Nitrogen (NOx). It will also measure Hydrocarbons (HC) but because the analyser's response is optimised for hexane, the HC readings from a diesel's exhaust will be inaccurate (very low maybe only 5% or so of true HC reading) and should be discounted. Note: To create representative levels of NOx, the engine must be under load.
Hydrocarbons are a family of compounds with a combination of hydrogen and carbon molecules Hx Cy. When using infra-red absorption as the measurement technique the particular calibration gas needs to be specified because different types of hydrocarbons are absorbed at different levels. The hydrocarbon sensor used in the KANE Automotive analysers is specifically set for the hydrocarbon compound known as hexane.
The gas concentrations that are measured in a car exhaust can be used to diagnose problems or faults within the engine or its management system. The difference in exhaust readings between cars with and without catalytic converters is huge. Note that NOx is only created when an engine is under load. To test for NOx the car must either be driven on the road or use be made of a dynamometer. When using a dynamometer for NOx testing the exhaust gases are extremely hot (the engine is under heavy load and there is no slipstream ventilation) so a high temperature exhaust probe must be used. NOx levels of 3000 to 4000 ppm are common even for new well tuned engines when under load.
Check filters are clean and the water trap is empty before use. Ensure the analyser is purged with fresh air after every use. Check that the batteries have enough charge to complete the test. When working on oil fired appliances always do a smoke test first. Please ensure you read the FAQs regarding: Cold Weather Water Damage
NOx is a general term pertaining to oxides of nitrogen, the most common being nitric oxide (NO) and nitrogen dioxide (NO2). Nitrogen oxides are typically created in the combustion process when burning fuels at high temperatures.
The reason the Gas Analyzer has failed may be because the sensors have become exhausted; the electro-chemical sensors have an operational life. The batteries may also be at a low voltage even if the unit has not been turned on, this is due to the internal memory and clock being powered all the time and most common batteries self discharge over time, lead acid batteries in particular.
Yes, it is vital that analysers are kept in a warm, dry place overnight. If an analyser is left in a vehicle on a cold night the next morning it may display "-----"O2 and not the expected 20.9% O2, (other readings taken by the analyser can also be affected). This happens because condensation can form on the oxygen sensor's inlet or even on the circuit board. This prevents correct operation and may cause damage to the analyser. If you experience this condition, it may be possible to rectify the problem yourself. Leave the instrument in a warm place for a few hours with the pump running. This may dry out the oxygen sensor enough to get a reading. If you still have problems please ring the service department.
Yes, if water is sucked into the analyser the inlet to the oxygen sensor can become blocked and it stops working. It will then display "-----" O2. Water can also damage the CO sensor. Where this happens, there will be a charge if the sensors need to be replaced. If you experience this condition, it may be possible to rectify the problem yourself. Leave the instrument in a warm place for a few hours with the pump running. This may dry out the oxygen sensor enough to get a reading. If you still have problems, please ring the Service Department.

- The ANSED Exhaust Gas Diagnostics Software is FREE with the purchase of the Gas Analyzer.
- The powerful algorithms in the software considers multiple factors and all gases simultaneously, not just the old two-dimensional fixed charts. The software uses a floating matrix formula for each gas that changes as the results change, taking into consideration several other variables of the vehicle tested to further enhance the accuracy of the formulas.
- Several possible solutions, in order of probability, are suggested by the software. The first suggestion is the likely cause in 75-80% of the situations, similar with the methodology of a scan tool.
The AUTOPLUS5 will log up to 100 tests these can be stored manually or automatically. These can then be transferred to a PC if required
You are able to print both live and stored readings using the optional InfraRed printer
It is advisable to check the filters regularly and ensure that any moisture is drained from the water trap. The compact design of the AUTOPLUS5 makes this very easy to do.
Compact design means a small pump which reduces the moisture content in the sample – Larger more expensive gas analyzers use larger pumps which improves response time but can cause issues with water ingress. This isn't a problem with AUTOPLUS5 Will AUTOPLUS5 require calibrating and servicingAs with all sensitive measuring instruments, it is recommended they are calibrated on a regular basis. Although sensor life is typically more than 18 months, the analyzer should be re-calibrated and serviced annually to stop any long-term sensor or electronics drift or accidental damage.

The two most important maintenance items for the user to perform: Drain the water trap as needed. Replace the filters when they are restricted – or on a monthly basis.
You can either purchase from your reseller, or direct online at www.ANSEDdiagnostics.com.
Items like the pump and water trap could easily last up to 4+ years, as long as the daily maintenance procedures of removing water from the water trap and changing the filters as needed. The Battery, Oxygen Sensor and NOX Sensor each have a more limited lifespan that is dependent upon usage. Most users can expect about 18 months use before a replacement is required. The typical life of a NOX Sensor is often about 2 years.
There are several things you can do that make a big difference in the life of the sensors: *Keep the water trap drained and never leave the probe on the garage floor where it may pick up water/antifreeze/oil/dirt or other debris. *Shut the pump off when not in use. *Use your analyzer frequently! The more you use the analyzer, the longer the life of the Oxygen sensor as it degrades over time in the presence of oxygen – and there should be little to no oxygen in the tailpipe sample of a running vehicle
