The following hardware errors are indicated by the software:
Symptoms Error message/description Solution
LED lashes red Pump overlow The hoses and/or the equipment
have illed with liquid or are blocked.
Stop operation and drain the liquid or remove the
blockage. If this is not possible, contact AVL DiTEST
service.
LED lashes red Operating temperature too high. The equipment is
used in a hot environment.
Stop the operation and let the equipment cool
down to 45 °C.
LED lashes red Operating temperature too low. The equipment is
used in a cold environment.
Operate the equipment in an environment of at
least 5 °C.
LED lashes red 5 V voltage supply outside of tolerance range.
Possible causes:
•The USB plug is dirty or corroded.
• The equipment is operated at the USB hub at the
same time as other equipment.
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.
This AVL DiTEST product is a high quality electrical and electronic device that should not be disposed of with household
