What to do if limit value exceeded in HC residue test on MAHA Test Equipment?
If a limit value is exceeded in the HC residue test on your MAHA Test Equipment, ensure that the sampling probe is positioned to avoid drawing in hydrocarbons from sources like exhaust gas or brake cleaner, and then restart the test. You can also rinse out the unit by running it in measurement mode for 2-3 minutes, making sure the probe doesn't take in any hydrocarbons. Additionally, try changing both F1 filters.
Why does my MAHA Test Equipment show "**.*" instead of measurement value?
If the MAHA Test Equipment displays "**.*" instead of a measurement value, this could be due to the ambient temperature being too high. Ensure that the environmental conditions are within the permitted range and allow the unit to cool down before switching it on. If the issue persists, contact service. Another possible cause is low gas flow. Check if the exhaust gas probe or sample gas outlet is blocked. Clean the probe with compressed air, replace the F1 filters, and ensure the flexible probe tubing is not buckled or obstructed. After checking these, turn the master switch off, wait 10 seconds, and then turn it back on. If the problem continues, contact service.
