I have inherited a smart gas meter (Landis & Gyr model G370) which is supposed to wake up when a button on its front is pressed, to take a reading manually. However, its display remains frustratingly blank despite my using buttons as instructed. Does this indicate that (1) the meter battery needs replacing, (2) the meter is faulty, or (3) the meter is configured for remote reading only and manual reading is not possible ? (The gas supplier's Help-line staff have so far been unable to provide a convincing answer).
Is it a legal requirement that the customer should be able to take readings manually, to check that billing is correct?
