What to do if I cannot switch off mru NOVAplus Measuring Instruments using the OFF key?
If the device does not react to any key presses, perform an emergency shut off by pressing ESC and ON simultaneously. Note that after doing this, you will need to set the date and time again.
Why mru Measuring Instruments has measurement without exact temperature values?
Call our after-sales service. Remove probe from the gas duct and condensate from the probe tube, because the thermo element is defective, balancing network interrupted or not connected.
