Reading The Landis & Gyr 370

If you have an in-home display, then you will either not be required to supply a meter reading, or you can take a reading from the display.  However, if you do require to get a meter reading from the meter itself then it is very simple.

On the front of the gas meter, there is a digital LCD screen.  Your gas meter is powered by a battery, so in order to save the battery life, the screen will automatically turn itself off.  You can turn on the screen by simply pressing the red button (just press and release the button).

When you have done this the screen will light up and say "please wait", it may take up to a minute, but the screen will eventually change to "credit on".  Once you see the screen say "credit on" press the red button again and the screen will change to say "meter index" followed by some numbers such as "00325.345", this is your meter reading, you only need the first five digits, in this case "00325".

That is your meter reading done, just leave the meter as it is, and the display will switch itself off in time.
