    verify the functionality of the power adapter by replacing it with a definitely functional unit; in case of doubt, measure the value of the supply voltage. If the power adapter is faulty, replace it. If the power adapter is functional with the correct supply voltage value and still no values are shown on the module’s LCD display, the module is most likely faulty.

  • Page 45: Sensor Failures

    replace the module according to the paragraph and perform the setting and check of overall functionality off the new module after that; if the module is not properly working even after its replacement for proven device and equipment, the trouble can be caused by local interference (jamming) from external source.
