By means of the meter’s primary key you can choose from and switch between the four display loops. When
delivered the meter is in transport state, which means that USER, TECH and ”SETUP loop”s are available. Depending
on country code, the access to ”SETUP loop” can be blocked in transport state and is thereby not available on
delivery. ”TEST loop” can only be accessed if the test seal (verification seal) is broken.
Keeping the primary key activated for 5, 7 and 9 seconds respectively you can change between the meter’s display
loops. ”TECH loop”, ”SETUP loop” and ”TEST loop” use index numbers as the readings in these display loops are
allocated to a specific index number. The index numbers facilitate navigation to the required reading. Index numbers
are not used in the configurable ”USER loop”. The below figure illustrates, how it is possible to navigate in the
meter’s display by means of the primary key.
In order to facilitate the diagnostics work, lines are shown in the display readings (current values) which are
influenced by any errors, and at the same time counting stops in the registers, which are influenced by the error. In
case of interrupted or short-circuited temperature sensor the corresponding display reading will include lines. No
lines are shown for flow measurement in case of flow sensor error “wrong flow direction” as this error does not
prevent the meter from measuring. If the flow sensor is prevented from measuring, e.g. due to air in the flow sensor,
the reading includes lines. The meter registers these errors and sets an info code, which can easily be read from the
meter’s display. Read more about the meter's info codes in paragraph 7.7.
