Check the USB connector and replace the cable if
necessary. Connect the equipment to a separate
USB port on the PC or supply the USB hub with a
separate power supply.
Software displays error message "Too little pressure
increase or too little pressure in the cooling system
detected!”
The engine cooling system or the measuring
system is leaking.
Stop the operation and the engine and let the
cooling system cool down. Check the engine and
measuring system for leaks. If necessary, contact
the AVL DiTEST service.
Software displays the error message "Calibration of
CO2 sensor necessary”
The CO2 sensor must be recalibrated.
Contact the AVL DiTEST service.
Software displays the error message "Overpressure
in cooling system detected!”
There is a defect in the engine cooling system (e.g.
a defective cylinder head gasket or the radiator fan
does not work).
Switch off the engine immediately and let the
system cool down before taking further steps.
Check the engine cooling system and correct any
malfunctions before starting a new measurement.
When the system stops responding, it is a fault in the CO2 coolant tester or the application running on it. Try to exit and restart the
software. If this is not possible, plug the equipment in again and again.
